Look on your rear bumper for 4 small (about 3/4") round disks. If they are not there then you do not have.

Yes, if you have the 4 discs in the bumper, you should have it. The vehicle needs to be in park for the "Park Assist" menu to come up on the DIC. Put the vehicle in park and press the trip button until you see "Park Assist". From there you should be able to turn it on.

If it is on (and working), back up to a wall or car, and it should beep as you get close.

Tried all this to no avail. Nothing shows up in the DIC even when in park. Very strange indeed.

 

There are 3 indicator lamps over the rear seat in the center of the headliner. Do you see any lights in the rear indicator when you shift to reverse?

 

for 2010- they removed the little lights in the rear.
(at least my 2010 Traverse does not have them)

Might be the case. The indicator appears on parts lists for vehicles with sunroofs, though. Couldn't find much info in the owner's manual. Seems that there is no discreet fuse for this, either. Would believe that some malfunction indicator lamp (light) MIL, or message would show on the instrument panel if there was a problem with the system.

 

should say SERVICE PARK ASSIST.

 

Look in the glove box for the RPO sticker then look for UD7 code - Sensor indicator - Rear Parking Assist.

You tried this?? (from the 2010 manual)

PARK ASSIST
To access this display, the vehicle
must be in P (Park). If your vehicle
has the Ultrasonic Rear Parking
Assist (URPA) system, press the
trip odometer reset stem until
PARK ASSIST displays. This
display allows the system to be
turned on or off. Once in this
display, press and hold the trip
odometer reset stem to select
between ON or OFF. If you choose
ON, the system will be turned on.
If you choose OFF, the system will
be turned off. The URPA system
automatically turns back on after
each vehicle start. When the URPA
system is turned off and the vehicle
is shifted out of P (Park), the DIC
will display the PARK ASSIST OFF
message as a reminder that the
system has been turned off. See
Object Detection System Messages
on page 5‑40 and Ultrasonic
Parking Assist on page 9‑35 for
more information.

The exception to this is if you have the V92 tow package and are hooked up using the 7 pin connector.
When the vehicle is started the "Park Assist off" appears everytime. You have to push a DIC button and then it will go away until the
next restart, as long as a trailer or the 7 pin plug has a connector in it. ;D

Trailers?? Did someone mention trailers?? :facepalm: It's covered later in the book anyway.

The UD7 code is indeed there.

Like Rbarrio I don't seem to have those lights.

Yes, I did see that in the manual. There is nothing in the DIC.

I have an aftermarket 7 pin connector and transmission cooler installed about two weeks after purchase. Once again nothing appears in the DIC.

There is a module in the rear that controls this. Maybe it's simply not sending a signal through the system. Something that would keep the vehicle from recognizing anything. :shrug:

 

Hmm....this guy has the same problem:

Unfortunately the OP never wrote anything about a resolution to his problem. :thumbdown:

 

Total guess is I have not looked at the wiring schematics (and haven't tried myself), but perhaps the aftermarket 7 pin connector is the cause. We see from that other thread, plugging something into the factory 7 pin disables rear park assist, so perhaps it is detecting a load and disabling it in both cases.

 

I bought here in Canada some time back a 2010 Acadia SLE AWD. Until now I wasn't aware that deep in my glove compartment was the original dealer sticker for my vehicle. It's a SLE with what called Preferred Group SLE 2. From the attached scan you can see I have something called "Rear Parking Assist". Is this the Ultrasonic parking assist?

If so I have never seen it work and cycling through the options in the Information Centre above the dash does not bring up anything that refers to it. I don't have the DIC buttons. Searching google for GMC Acadia parking sensors will bring up a bumper that looks like mine with fours sensors and there seems to be a non-sensor bumper also.

Is this just not turned on for some reason or "rear parking assist" is not what I think it is?

???

What I don't understand is the comment that you don't have DIC buttons. And in your signature you claim "Considering DIC"

If you don't have buttons how are you scrolling through the options?
Maybe the Canada models are different?

If you really want to dive into this project - then I think if you can find the wires going to the sensors you should be able to check them for voltage.
Of course you would need someone to put the vehicle in reverse with the brakes on close to a wall or something that should set off the sensors.
If there is no voltage going to the sensors then you know something North of there is wrong.
Like the previous poster said - the after market 7 pin might be the problem or part of the problem. Unplug it if you can and try it again.

Is there any possibility that this vehicle was a rental at one time? Even if the code is in the glovebox is there any possibility that a rental vehicle would have
that feature disabled? IDK.

IS there any possibility that you bought an extended warranty? I would think this would be covered under the bumper to bumper warranty.

OK I looked in my service manual and there is a Rear Object Alarm Module Scan Tool Information section.
There appears to be a Loudspeaker feed voltage output listed so maybe the system could be working but you can't hear it. ???
They also mention and "Inhibit" in the system status - so if that was tripped that could be the problem.
I'm going to assume that the dealer has this tool and could "look" to see if any history of why it's not working exists.

So It might come down to how bad you want this feature to work.
I don't know what else to tell you. Good luck.

The 2012 and earlier SLE and SLE-2 models did not have the (four) Enhanced DIC buttons (check mark, info, settings, ?) and only had the push button stalk in the instrument cluster. The stalk allowed drivers to reset messages and scroll through a very basic version of the DIC. It did not permit various settings to be changed (lights, sounds, ect) and did not display info such as individual tire pressure, fuel range, timer, fuel used.

Some of us have added those buttons to our SLE trim level Acadias and got all the functions unlocked.

I wish... my 2012 with the V92 does not disable the Park Assist just because the trailer wiring is plugged in. My 2010 didn't either, and I always wished it had that very simple circuit installed... maybe it's a Canada thing :shrug:

 

mine will turn it off-- when I put my hitch cargo rack-- or bike rack.
the cargo rack has the plug for the lights..
the bike rack has not lights.

It appears the sensors pick up that there is an item very close and 'knows' the hitch is in use.
and turns it off.

 

I have an aftermarket 7 pin connector and transmission cooler installed about two weeks after purchase. Once again nothing appears in the DIC.

Good question ... ... Have you checked condition of all the fuses related to the trailer ... not just a visual inspection ... checked with an ohm meter?

Mine will do that too, if the carrier stays on the hitch and blocks the sensors (just like snow will) during forward and reverse it will turn off the park assist, with or without the plug installed. I just wish it would automatically disable the system just by plugging-in.
