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(R) is updated with the latest software version.
