Just had an issue on my 2007 Acadia SLT2 that I couldn't find any info on anywhere, so I thought I would post here for the next guy in my situation. Both my Tire Pressure Monitor System and my Remote Keyless Entry would not allow me to enter the relearn protocol through the DIC or by holding lock and unlock on the remotes. When I pressed the check mark on the DIC, the display just flashed the same message at me, ot wouldn't actually enter the relearn mode. It turns out that the fix for my issue was to pull the "DISPLAY" fuse and reinstall. Apparently the Remote Control Door Lock Receiver (RCDLR) is on the DISPLAY circuit. The TIre Pressure Monitor System (TPMS) and the Remote Keyless Entry (RKE) use this wireless receiver. Problem solved, and thanks to JustAnswer.com for helping me figure it out.
tynee
so I was looking at this info-- and it seems its on the left.????
Found this write up regarding an issue with some 2007-2008 vehicles. Unless someone has been in the area where these wires are located you shouldn't have this problem. Good information on how to get to the module in the writeup.
Condition
Some customers may comment on limited or poor transmitter range when using the remote keyless entry (RKE) and/or remote vehicle start (RVS).
Cause
This condition may be caused by radio frequency interference (RFI) with OnStar® because a section of the remote control door lock receiver (RCDLR) wire harness is missing the foil wrap shielding tape.
Correction
Notice: DAMAGE to the left rear quarter trim panel may result if the procedure for the Rear Quarter Lower Trim Panel Replacement is not followed in SI. Prior to removing the left rear quarter trim panel, make sure that the two hidden screws are removed and the speaker connector is disconnected from the panel.
Disconnect the OnStar® VCIM fuse and test the range for the RVS and RKE. If there is no change in range continue to diagnose the condition using SI. If the range improves, separate RCDLR circuits 1840, 560 and 650 from left rear body harness; then add shielding 3M™ Aluminum Foil Tape 425 Silver, or equivalent, to the RCDLR wire harness using the steps below.
Open the rear liftgate and the rear doors.
Position the second and third row seats to the flip up forward positions.
Remove the rear storage compartment. Refer to Rear Storage Compartment Replacement in SI.
Remove the rear liftgate door sill plate. Refer to Liftgate Door Sill Plate Replacement in SI.
Remove the left rear door sill plate. Refer to Rear Carpet Retainer Replacement in SI.
Remove the left body upper trim panel. Refer to Body Lock Pillar Upper Trim Panel Replacement in SI.
Remove the left and right rear quarter upper trim panel. Refer to Quarter Upper Trim Panel Replacement in SI.
Important: There are two hidden screws, one screw (1) is behind the cargo screen retainer and the second screw (2) is under the armrest. The cargo retainer will need to be removed by turning, twisting and pulling outward to release the retainer. The electrical connector for the rear speaker and outlet will also need to be disconnected prior to removing the panel.
Remove the left rear lower quarter trim panel. Refer to Rear Quarter Lower Trim Panel Replacement in SI. If the vehicle is equipped with a power liftgate, unbolt and reposition the liftgate actuator assembly to the side. Refer to Liftgate Actuator Replacement in SI.
Tip: A small block may be placed between the headliner and the roof panel to gain access to the RCDLR module. Be careful not to crease the headliner panel.
Lower the rear of the headliner panel to gain access to the RCDLR module (Rear center of roof, above the cargo lamp and headliner).
Disconnect the RCDLR connector (Green in Color) from the RCDLR module.
Unclip the left rear body harness retainers from the vehicle, starting at the roof panel working down to the left rear corner of the vehicle.
Cut the RCDLR connector off, leaving enough wire to reattach the connector later in Step 14.
