Condition/Concern
Some customers may comment that the power driver seat is inoperative. They may also comment that the power
outside mirror and power passenger seat (XTS only) is inoperative.
Recommendation/Instructions
Important: Do not replace the memory seat module for this concern.
Confirm the power driver seat or power passenger seat (XTS only) does not move in any direction using the seat
adjustment switch. If the seat(s) are inoperative in all directions, determine the following information:
1. Using the GDS2, request DTC information from the memory seat module (MSM). Does it report "no
communication" with the MSM?
2. Did other modules set a U0208 (Loss of Communication with Memory Seat Module) DTC?
• If both steps are yes, proceed to step 3.
• If either step is no, this bulletin does not apply. Refer to published diagnostics in SI.
3. Engineering is aware of this concern and working on a long term resolution. In the meantime, the memory seat
module logic fuse can be removed for at least 10 seconds. This action will remove power from the memory seat
module and reset the module. After the module has been reset, power seat and mirror functionality will return.
Customer Information
Please communicate to the customer that we apologize for this inconvenience and that General Motors is working
on a solution for this concern. Once a solution is available, this PI will be updated with additional details - allowing
dealership personnel to contact the customer to schedule a service appointment and repair the vehicle.
