document ID 1914921.  Addresses three separate issues:

(1) Wiring harness under driver seat.  Remove seat,
inspect harness for binding/pinching tie wrap harness
out of harms way.  Don't attempt yourself, an airbag
module is nearby.  Only applies to vehicles with power/memory
driver's seat.

(2)  Open/close rear lift gate 3 times in succession
using the switches on the liftgate.  If no problem,
nothing further is required.  If problem, replace
switch(s).
 
(3)  Lubricate the I-shaft bearing/boot with GM
Superlube®, or equivalent, to relieve the friction
between the boot and the carrier.  This is a simple
procedure to lubricate the intermediate steering shaft
boot/carrier contact points and is done from the
interior of the vehicle.

Models:
2008 Buick Enclave
2007 GMC Acadia
2007 Saturn Outlook
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some customers may comment of a hum or moan noise when driving 66 - 70 mph on a smooth road. It may sound
like a bearing noise, but actually may be tires. A slight roughness may also be felt. A small number of P255/65R18
Goodyear Fortera tires may set up this humming noise, due to slight variations in the manufacture of the tire. It will
be noticed only when the offending tires are on the front positions of the vehicle.
Recommendation/Instructions:
If this condition is encountered, Do Not Replace Wheel Bearings. First, swap the tires front to back, and road test
again. If the noise goes away, tires are the cause. If the noise is still there, replace with a known good set of tires from
another vehicle and retest.
Tires built the 19th week of 2007 (Dot date 1907, this is the Last four digits of the DOT) and later will have a slight
manufacturing modification to correct this condition.
Note: Goodyear will start production of the modified tire the week of May 6th, 19th (Dot date 1907) week of the year.
Therefore it may be some time before these tires are available for service in the field. Replacing the tires with ones
produced the 18th (Dot date 1807) week of the year or earlier may not resolve the concern. This PI will be updated
once more information is available. The intent of this information is to prevent wheel bearing misdiagnosis.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

seal thermal TXV valve warm #PIT4379 - (05/03/2007)
Models:
2008 Buick Enclave
2007 GMC Acadia
2007 Saturn Outlook
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
The Air Conditioner (AC) is inoperative or blows warm air. This can be caused by a low state of refrigerant charge. If
a low state of charge is found, check for leaks at the front Thermal Expansion Valve (TXV).
Recommendation/Instructions:
If a leak is found at the front Thermal Expansion Valve (TXV), do not replace the Thermal Expansion Valve (TXV).
It will be necessary to replace the 4 seals at the TXV (2 on back side of TXV at evaporator core fittings and 2 on front
side at condenser tube and evaporator hose connections). Follow the instructions in SI for Thermal Expansion Valve
Replacement.
Note: It is very important to make sure the TXV mounting surface is clean and free of any debris and lint prior to
reinstalling the TXV. It is also very important to make sure to properly torque the bolts for the TXV. The torque
specifications are as follows.
The 2 bolts that attach the TXV to the evaporator 5 N·m (44 lb in).
The nut the attaches the lines to the TXV 20 N·m (15 lb ft).
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

#PIT4374 - (05/02/2007)
Models:
2008 Buick Enclave
2007 GMC Acadia
2007 Saturn Outlook
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
A customer and/or technician may comment that when using the Power Liftgate, it will open fully, drop a few inches,
then power close. There will likely be a loud noise as the clutch engages during this event.
Recommendation/Instructions:
Turn off the Power Liftgate, using the Disable Switch in the bottom of the center stack. Manually open the liftgate to
the full open position using the Release Switch on the exterior liftgate pull handle. Verify that the liftgate will remain
at or near the full open position for several minutes. If the liftgate will not remain open, replace the liftgate strut(s)
that are weak. Though both struts should be inspected for weakness, it is often only the LH strut that requires
replacement. It is important to note that the LH and RH Assist Struts have two different part numbers and each should
be installed in its proper location.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

Models:
2008 Buick Enclave
2007 GMC Acadia
2007 Saturn Outlook
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
A clunk, thud or pop noise may be heard or felt in the LF area of the vehicle during the Anti-Lock Brake System
(ABS) initialization self test. Some customers or technicians may describe the noise by saying it is similar to driving
over a manhole cover. This will happen one time per ignition cycle. This test will start when the vehicle is driven at a
speed greater than 12 km/h (7.5 mph) and the EBCM has not detected any traction control module (TCS)/vehicle
stability enhancement system (VSES) related malfunctions, and the brakes are not applied. The EBCM isolates all of
the wheels by closing the 4 isolation valves. Due to the fact that all of the wheels are isolated during the second phase
of the test, the test must be aborted if the brake is applied while the test is being performed. Occasionally, the driver
may detect this by experiencing a clunk, thud or pop noise or a momentary hard pedal.
Recommendation/Instructions:
This clunk, thud or pop noise is a normal characteristic of the Anti-Lock Brake System (ABS) initialization self test,
and no repairs should be made.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

2007 GMC Acadia
2007 Saturn Outlook
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
The Remote Vehicle Start (RVS) is inoperative after adding this option.
Recommendation/Instructions:
It is very important to follow all the steps on the instruction sheet that comes with the accessories transmitter kit.
Below are some of the key points for installing the remote vehicle start option.
This will require reprogramming the Theft Deterrent Module (TDM) using TIS2WEB. Select the calibration with
remote start.
This will require a call to TCSC (1-800-828-6860) so the calibration for the BCM can be reconfigured.
Reprogram the BCM using TIS2WEB.
Important: After programming the BCM, perform the following to avoid future misdiagnosis:
• Turn the ignition OFF for 1 minute.
• Turn the ignition ON with the engine OFF.
• Setup the BCM using the scan tool.
• Navigate to the following on the scan tool: Vehicle Control Systems > Module Setup > Body
Control Module
• Recalibrate the brake pedal position (BPP) sensor by selecting "BPP Sensor Calibration" and
• Relearn the restraints ID by selecting "Setup SDM Primary Key in BCM"
Program the new transmitters to the remote control door lock receiver using the scan tool.
Important: Program the new transmitters into key fob slots 1 and 2. This will enable diagnostics on the transmitters.
Any other transmitters should be programmed into slots 3 and 4.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some customers may comment that excessive noise is heard from the under hood area while driving off road and
turning sharply in either direction. This noise is caused by a Vehicle Stability Enhancement System activation and is
considered to be normal under these operating conditions.
Recommendation/Instructions:
No repair attempt should be made for this condition.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.


Document ID# 1963820
Subject: Platform Battery Drain Diagnosis Process - keywords accessory
aftermarket generator low operation regulator volt voltage
#PIC3589B - (04/20/2007)
Models: 1996-2007 Passenger Cars and Light Duty Trucks that use Class
2 communications
This PI Supercedes To Include 2007 Model Year. Please Discard PIC3589A.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Platform Battery Drain Diagnosis Process - Battery is discharged for no apparent reason while vehicle is parked and
locked - Intermittent draw and/or possible continuous draw(s) that slowly renders the battery below its serviceable
voltage amperage level.
Please follow this process entirely:
Define the conditions which trigger the discharged battery:
• How long does it take for the battery to discharge? This step will help determine if the draw is
large or small. Normally a draw, which takes the battery level down overnight after operating
the vehicle the day before, is rather large and is related to a switch, relay or other
electric/mechanical device. Small amounts of drain which take several days to take the battery
from a good state of charge to below the level required to start the engine can be small single
bulbs or modules which are either not going to sleep when they should, or waking up
intermittently for some unknown reason.
• How many times has it happened to the customer? This step will determine if this is a
Random occurrence and/or intermittent.
• Does it always happen in the same location? Is there some outside influence that surrounds the
vehicle that needs to be taken into account? This is most unlikely, but worth checking-out.
• Describe the customer's driving habits. Does the battery get to a state of being fully charged
on a regular basis or is this vehicle unable to crank due to a generally low state of charge?
• Is the vehicle equipped with any non-original equipment including cell phone, remote starter,
extra lighting, radio, CD player, LOJAK, etc. or OnStar (either dealer or factory installed)? All
of these items can be wired in such a way to either constantly draw amperage, which they
shouldn't, or in some way affect the class 2 modules on this vehicle and/or the battery and
charging system.
• Does the customer leave the key in the ignition? Leaving the key in the ignition does not
generally cause a problem, but if the customer does not come back to the locked ignition
position after shutting the engine off however, many draws will be induced. This draw will not
be reduced and/or eliminated, this type of draw is due to the fact that the system is designed to
keep certain modules awake with the key in this position.
• What is the previous history on this car, what parts have been replaced, what repairs have been
performed either in an attempt to correct this situation or that might impact it? Are there any
other reported problems with the vehicle which may relate to a discharged battery concern -
items which were previously reported/corrected and/or currently exist that the customer (car
recently bought used) does not recognize as a problem or the used car manager reporting the
discharged battery is unaware of? Recent repairs may or may not relate to draw diagnosis; i.e.
the IPC was replaced recently.
Perform a good visual and physical inspection of the battery cables. CHECK TORQUE OF BATTERY CABLE
BOLTS. If loose, check for signs of arcing and corrosion etc., grounds and power leads to and from each of
these, or BOLT MATERIAL IN BATTERY THREADS, THERMISTOR (if equipped) CONNECTOR FOR
PROPER SEATING AND TIGHTNESS. What are the results of a battery/CHARGING SYSTEM test?
• Perform a generator output test and a terminal drag test on generator terminal L.
• Fuses related to this concern: check for loose fuses in trunk and engine compartment bussed
electrical center by rocking each fuse with one finger, which may help identify the fuse. The
only repairs that may be made to the electrical center are replacement of plug-in devices and
mounting hardware, as follows: fuses, relays, circuit breakers, electrical center cover, battery
stud cover, and other snap-on covers, cover attachment thumb screw, labels for fuse/relay
identification, splash shields, and mounting brackets
What DTCs are currently present or have been recorded on previous visits to the dealer? Correct as per the
appropriate service manual.
Road test vehicle for 30-40 minutes, activate all accessories. Open and close all doors, windows, deck lid, etc.
CYCLE LUMBAR AND SEAT SWITCHES along with all other manually operated switches including the
trunk release, fuel door release, garage door opener, and valet that have power to them all the time while the
car is sitting. Don't forget to look FOR A STUCK SWITCH/RELAY
What is the parasitic draw on the vehicle after a 25-minute power down cycle? Using parasitic draw test switch
tool J38758 and a DVOM J39200, perform a parasitic draw test as per the procedure in Section 6 Engine
Electrical of the most current Service Manual. Record the draw and read the reserve capacity of the battery in
the vehicle. Divide the reserve capacity by four (4) and the draw present should not exceed this number.
Example: If the battery has a reserve capacity of 100 amperes, the current draw should not exceed 25 mA on
the DVOM. See section 6 of the appropriate service manual for acceptable draw limits for each module the
vehicle may be equipped with. Keep in mind the draw created by the OnStar system for the first 48 hours from
ignition off. The system will cycle every 10 minutes and cause a spike to approximately 250 mA for about ten
seconds, taper down to 75 mA for another 45 seconds and go to less than one mA for the nine minutes until
the next cycle begins. This is normal. The Class 2 data line should not wake up during this sequence. This
cycle stops if power is removed from the OnStar system for a short period and will resume once the GPS
signal is reacquired.
If the draw above is determined to be above the appropriate amount for the vehicle involved, are any modules on
the class 2 data line staying "active" past the 25-minute time out mentioned above or waking up periodically
after this time-out has passed? If one or more module is waking up, how many times and which module(s)?
Use the Tech 2 and use the message monitor screen with an external power source to the Tech 2 if performing
an amp draw test while using message monitor.
Recommendation/Instructions:
Here is a suggested procedure for performing a combination parasitic draw test while monitoring the class 2 devices
on the vehicle:
Remove terminal 16 from data link connector (DLC).
Install tool #J38758 on battery.
Connect Fluke 87 to J38758 as described in section 6 of the appropriate Service Manual and set to appropriate
amp scale
Connect Tech 2 to DLC
Connect 110-volt power supply to DLC end of Tech 2 cable.
Turn Tech 2 on
• Main, enter
• Diagnostics enter.
• Year
• Vehicle type
• Diagnostic circuit check
• Class 2 message monitor - remember; only modules which are currently communicating on
the Class 2 data line will show up on the message monitor screen. If the ignition is in the
accessory position as an example, the PCM and ABS controller will not be listed. If a module,
which the vehicle is known to be equipped with, does not show up on message monitor when
in the run position, this indicates a problem that needs correction prior to proceeding.
Allow vehicle to sit with all doors closed and without activating any switches etc. until class 2 system has had
enough time to power down, less than 25 minutes, or use the sleep mode to put all the modules to sleep. Once
the sleep mode is enabled, the first module to "wake up" will be listed first on the message monitor screen
with others listed in order of "wake up". The time from being put to sleep until the first "wake up" sequence
will also be displayed. If a combination of three or four modules has come active, putting all of the modules
back to sleep and pulling the fuse to one module at a time will help to narrow down which module may be
waking up inadvertently. Remember that module "wake up" can be caused by several factors. They include,
but are not limited to:
• nput changing states - door switch going open and closed (hi/lo)
• power or ground coming and going to module
• module internal function incorrect
• Or in the case of the power master, amperage draws in excess of low power requirements or
another module which has these or other related concerns. These all can be checked with the
Fluke set to 1 millisecond record speed on min/max setting.
Open gate on J tool, and let vehicle sit for another ten (10) minutes and/or use sleep mode.
Review the amperage reading.
As the amperage draw tapers down below 10 amps, close the J38758 and switch Fluke 87 to milliamp scale and
record min/max on 100-millisecond scale. Open the J38758 again when done. This step will allow the Fluke
meter to record any spikes and keep the meter working during the entire sequence. IF MIN/MAX IS NOT
SELECTED, THE METER WILL TIME OUT AND SHUT OFF.
After the vehicle has been sitting for the necessary time, check the number of counts as per message monitor for
each control module, i.e. each time a unit goes from inactive, to active and inactive again. The module(s) with
the highest number of counts may indicate a suspect area. Modules may be waking up on their own, (which is
most unlikely) or activated by a switch input, power fluctuation, poor ground or input from other modules
which are being activated.
Once it has been determined that the draw is either a component - relay, switch etc., which is stuck or in some
way reduces/contributes to the draw, determine which circuits are specifically involved. Touching and/or
removing fuses, relays, and connectors to suspect components after reviewing the current wiring diagram until
the draw is reduced to acceptable levels will lead to the correct circuit. When exiting the message monitor
screen and then re-entering the message monitor screen, the Tech 2 will also wake up modules. DON'T BE
FOOLED. Wait for the module(s) to again go to sleep or use the sleep mode function.
Back-to-basics:
• Checking ground credibility requires a voltage drop test under load
• ALWAYS TEST FROM THE NEGATIVE SIDE OF THE CIRCUIT - A voltage drop test is
performed at various points along the circuit from the ground side toward the positive side of
the circuit until the point of high resistance is located.
• ALWAYS MAKE CERTAIN THAT THE CIRCUIT LOAD IS "ON"
• ALWAYS USE A HIGH IMPEDANCE METER LIKE A FLUKE 87
• THE HIGHER THE VOLTAGE READING, THE HIGHER THE RESISTANCE IN THAT
CIRCUIT
• WHEN TESTING, TRY TO ACHIEVE A READING AS CLOSE TO ZERO AS POSSIBLE
(USUALLY LESS THAN 25 MILLIVOLTS)
• ALWAYS START WITH A FULLY CHARGED BATTERY!
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
An owner may report that the OnStar system is attempting and/or completing phone calls which the operator of the
vehicle did not initiate.
It is important to know which type of reported "Phantom Phone Call" the operator is reporting. Some phone calls of
this nature are considered normal and cannot be addressed other than through education while others may require
some remedial action to resolve.
Below are the areas which we have found to contribute to this type of reported calls.
Generation 1 = Dealer installed handset system
Generation 2 = Three button kit/factory installed system - formally referred to as 2.0 system
Generation 3 = Three button factory installed system capable of OnStar Hands Free Calling (HFC) - formally referred
to as 2.6 system
Generation 4 = Three button factory installed system capable of HFC and Memo Record - formally referred to as F1
system
Generation 5 = Three button factory installed system capable of HFC, Memo Record and Dual Tone Multi-funcition
Tones (DTMF) - Analog system
Generation 6 = Three button factory installed system capable of HFC, Memo Record and DTMF - Digital/Analog
system
Generation 7 = Three button factory installed system capable of HFC, Memo Record and DTMF - Digital/Analog
system
Geo MIN = the phone number, geographically assigned, to each OnStar system
Scenario number one:
The vehicle/owner may be receiving calls (apparently HFC) at any time. When the customer attempts to answer there
is no one there. In this case (with a Geo MIN) someone is actually dialing the phone number assigned to the OnStar
system within the vehicle and hanging up when they hear someone answer the phone unexpectedly. A typical wrong
number was dialed. Keep scenario number three below in mind also.
Scenario number two:
This may involve a phantom call made to the OnStar call center. We believe the majority of these are due to the
addition of the words "OnStar" and "Emergency" to the voice recognition capability on Gen 5 and above systems. The
customer may press the White dot button or the steering wheel control button and the system misinterprets a sound or
the spoken word as either OnStar or emergency and places a call. This may be caused by either background noise or a
cough etc. as well.
Scenario number three:
This third area has to do with the behavior of the Gen 4 and Gen 5 OnStar hardware. If the OnStar call center makes
an outbound call to the car it will only ring once in the vehicle before the call is automatically answered by the
hardware - called auto-answer (Gen 3 rings indefinitely or until a white dot button press). If the customer presses the
white dot button the system will disconnect the OnStar advisor from the vehicle. In this scenario the call center would
only be calling back if they were disconnected at some point in time.
Scenario number four:
Because the button assembly and associated wiring feeds voltage back to the OnStar system based on the amount of
voltage drop through each of the buttons, should the return line be partially shorted to voltage the system could
interpret this voltage as a key press. If one of the buttons voltage is simulated, such as the Blue button, the system will
make a phone call just as if the button had been pressed by the operator of the vehicle.
Scenario number five (Gen 2 and 3 only):
An outbound call is being made and will likely not complete and result in modem tone screech or fast busy beeping.
The button assembly LED may or may not flash. The operator will not be able to end call by pressing the Call
Answer/Call End (DOT) button. "Connecting to OnStar" jingle is not heard. This condition may result in a dead
battery. If "Connecting to OnStar" jingle is NOT heard, replace VCU with appropriate part. If jingle is heard, follow
normal diagnostics checking for unintentional call initiation and integrity of circuits between OnStar VIU module and
OnStar Button Assembly.
When attempting resolution it is very important to determine under which circumstances the reported Phantom Phone
call resulted.
Recommendation/Instructions:
Most of these type calls have been found to be operator error and/or phone calls being incoming placed to the
assigned phone number for the vehicle involved.
Some education and/or duplication of the concern may be required to further analyze and determine the type of calls
the system is transmitting and/or receiving prior to any actual repair.
Repair/education as required after a thorough diagnosis.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

2007 GMC Acadia
2007 Saturn Outlook
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
SERVICE VME
Some customers may comment about a helicopter type noise when a rear window is lowered. This is a common
occurrence especially on vehicles with an SUV styled or boxy rear end. This is known as buffeting and it is a low
frequency, high level wind noise perceived in a moving vehicle at certain speeds with a window open.
On a customer vehicle, buffeting with a rear window down can be minimized by dropping a front door glass by 1 to 2
inches. Accessory weather deflectors along the front door glass can also be effective in deflecting the airflow
sufficiently from an open window to alleviate buffeting.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

This PI was superseded to update models and model years. Please discard PIT4209.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
With the launch of the all new Buick Enclave, GMC Acadia and Saturn Outlook, it is
important that our customers experience the highest quality with their vehicle upon delivery. With that said, an all
new "Smart Slide" seat feature is utilized for the second row seating. This seat feature allows easy access to the third
row seating by allowing the second row seat to slide forward with minimal effort. When incorporating the "Smart
Slide" seats along with the OEM floor mats, the seat may seem difficult to operate or bind on the floor mat. It is
important that during the PDI process, the floor mat is folded per the directions below to prevent any difficulty when
using the "Smart Slide" seat feature.
Recommendation/Instructions:
Simply fold the mat as shown below and hold for a few seconds, setting the fold memory.
The mat will return to its flat position when the seat is returned to its operational position.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

This PI was superseded to update models and years. Please discard PIT4189.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some Buick Enclave, GMC Acadia and Saturn Outlook vehicles may be equipped with the optional Navigation Radio,
RPO UZR. There have been questions and concerns that the Navigation DVD is inoperative. Further questioning
and/or inspection revealed that the Navigation DVD was being installed in the CD media slot. This new radio has one
media slot CD/MP3 discs and a second media slot for Navigation DVD. The CD media slot resides above the
Navigation display and the Navigation DVD media slot resides behind the Navigation display.
Recommendation/Instructions:
It is recommended that during the PDI process that the Navigation DVD is installed prior to delivery. This disc is
inserted behind the Navigation display. Press and hold the eject button next to the CD media slot for approximately 15
seconds. The radio will then eject/tilt the Navigation display. Behind the Navigation display resides a media slot
specifically for the Navigation DVD. Install the DVD. To close the display, it will require two hands (one on each
side of the display) and push the display in evenly toward the Navigation radio until it is secured.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
There have been a number of returned SDMs and calls to TAC for problems that occurred when reprogramming the
SDM. Here are some tips regarding SDM reprogramming.
Recommendation/Instructions:
The battery voltage needs to be in the normal operating range during the entire programming process. If the
battery is weak, make sure to fully charge the battery prior programming.
Do not try to reprogram the SDM with current codes (DTCs) (history DTCs are OK), address the codes using the
appropriate SI document. If an SDM is reprogrammed with current faults, other DTCs in addition to the
original DTC will be set.
If the airbag light is blinking and there are current DTCs; address the codes using the appropriate SI document.
The SDM setup can not be completed until all the current SDM DTCs are cleared.
If the airbag light is blinking continuously with no codes, the SDM is ready to be set up. Complete the setup
procedure in the Tech 2. If after successfully completing the SDM setup procedure and the airbag lamp is still
blinking, complete the Rollover Sensor setup procedure on the Tech 2.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

Models:
2007 GMC Acadia
2007 Saturn Outlook
This PI was superseded to correct the connector numbers from J202 to X202, and added the J251 and J215
splices. Please discard PIT4247B.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
The dome lamps are inoperative or the dome lamps stay on at all times and never time out. The Tech 2 will not be
able to command the lamps on or off. This will not be an intermittent concern. This can be caused by an open in
ground circuit 1551 to the BCM. If circuit 1551 is open, it is possible for the main BCM ground to internally back
feed through the BCM dome lamp circuits and cause internal damage to the BCM.
Recommendation/Instructions:
If SI diagnostics leads to replace the BCM, Check the ground circuit 1551 for an open. Circuit 1551 passes through
the J251 splice to the J215 splice to the X202 connector and then grounds at G301. Check ground G301 (near the base
of the left A-pillar) and in-line connector X202 (In the instrument panel harness, right top of the instrument panel,
behind the instrument panel air bag) for a loose or poor connection. Please repair any concerns with the ground circuit
1551 before installing the new BCM. Only replace the BCM if SI diagnostics leads to it.
Note: When doing any diagnostic checks related to the X202 connector or the G301 ground, it is very important to
either (Disconnect the negative side of the battery) or (Disconnect the X3 connector on the BCM) prior to
disconnecting the X202 connector or removing the G301 ground.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is

Models:
2007 GMC Acadia
2007 Saturn Outlook
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
GM Engineering has investigated reports of rusty or corroded appearance of undercarriage components, including
uncoated suspension fasteners, exhaust pipe and ball joint housings. This condition may be present on new vehicles
being received at the dealer off the transport truck. During certain times of the year, vehicles being produced in
Michigan may be subjected to salt used to maintain roads in the winter months. This salt may be present on the plant
premises, city streets around the plant or on the transport truck during transit between the plant and the dealer. Some
of the undercarriage components may have some corrosion upon arrival at the dealer as a result of this salt exposure.
Over time these components will have a uniform discoloration which looks like rust. With this said, these components
have been tested and would last 10+ years in normal service. Additionally, these components should be limited to
those not in the clear vision of the customer. The Vehicle Technical Specifications specify that cosmetic corrosion on
these parts that are out of the clear vision of the final customer is acceptable. These components have minimal
protective coatings and surface corrosion can form on these parts that will not represent a safety or durability concern.
Recommendation/Instructions:
These components should not be replaced for this surface or cosmetic corrosion.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

2007 Saturn Outlook
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
The Rear HVAC system may come on unexpectedly. This condition may occur on vehicles with either a Front
Manual or Front Automatic HVAC controlled system combined with a Rear Manual HVAC control (non-RSA). This
concern is most likely to occur when the Rear HVAC control knobs are placed "in-between detents".
Recommendation/Instructions:
Do not make any repair for this concern at this time. Engineering is aware of the concern and is working on a fix.
Until a fix becomes available, advise the customer of the following.
The system is completely functional. Advise the customer if the system turns on unexpectedly, they just need to turn
Rear HVAC system off (via AUX button on front control head or Fan knob to OFF on rear control). Since this
concern is most likely to occur when the Rear HVAC control knobs are placed "in-between detents", advise the
customer to make sure the rear control knobs are fully in the detents. This should minimize/eliminate the potential of
this occurring.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.

I removed the Recalls and Campaigns from this thread and put them in their own.  This will hopefully make them easier to locate for those that are interested.  This thread now only lists TSBs, and even then not all of them will be here as the list published by GM is quite extensive and not all necessarily apply to the Acadia and Lambda siblings.

If anyone has a site where the TSB lists can be displayed, I'd be happy to add a link to it. 

Here's one you can try:
