Memory Function of Memory Seats Inoperative After Air Bag Deployment (Reprogram Memory Seat Module)

TECHNICAL SERVICE BULLETIN

Reference Number(s): 09-08-50-014, Date of Issue: August 28, 2009

Affected Model(s):

2008-2009 Cadillac Escalade, Escalade ESV, Escalade EXT; 2008-2009 Chevrolet Avalanche, Silverado, Suburban, Tahoe; 2008-2009 GMC Sierra, Yukon, Yukon XL; 2008-2009 HUMMER H2, H2 SUT; Built Between April, 2008 and May, 2009

Condition

Some customers may comment that the memory function of the memory seats becomes inoperative after an air bag deployment. Vehicles built between of April 2008 and May, 2009 that have incurred an air bag deployment will no longer have seat memory functionality. The memory set and recall features will exhibit no automatic recalls, and no set or recall through the memory switches, along with no audible feedback. The driver seat/column/pedal can still be moved with the appropriate switches. The heat/cool functionality is not affected.

Cause

This condition may be caused by the air bag deployed flag getting permanently stored in the memory seat module.

Correction

Reprogram the Memory Seat Module (MSM) with the latest software calibration.

IMPORTANT: Select the correct calibration files for the appropriate vehicle configuration (body style) and RPO codes.

A revised calibration has been developed to address this condition. Technicians are to reprogram the MSM using the Service Programming System (SPS) with the latest software available on TIS2WEB. Refer to Memory Seat Control Module Programming and Setup in SI. As always, make sure your Tech 2® is updated with the latest software version.
