Please discard Corporate Bulletin Number 03-08-44-002 (Section 08 - Body and Accessories).
Condition
Some customers may comment that the radio and HVAC settings change while driving down the road. However the seat does not move.
Cause
Due to the position of the memory buttons on the driver's door pad, a customer may inadvertently depress a memory button.
Correction
A new software package has been developed. The new software will not allow the radio and HVAC settings to change when the transmission shift lever
is in any gear other than Park.
Reprogram the Body Control Module using the normal SPS reprogramming procedure (TIS version 1.0 released January 2003, or newer).
Warranty Information
For vehicles repaired under warranty, use the table.
