COMPLAINT

Seat Moves to Incorrect Position When Using Easy Entry/Exit Feature

CAUSE

If you receive customer reports in the above model vehicles with the below symptoms, this may be due to a software error in the Electronic Ignition Switch (EIS). The EIS may be sending the incorrect key memory block number, which would move the driver side seat to the incorrect position.

After entering the vehicle and inserting the key in the ignition, the driver side seat adjustment during Easy Entry/ Exit activation does not move to the location stored in memory.
No stored or present fault codes in control units used in executing the Easy Entry/Exit feature.

REMEDY

To resolve, replace the EIS as per WIS document AR46.10-P-0810P with one of the part numbers listed below (or its successor).

NOTE: For vehicles listed above as of model year 2006 (with code 806), the Easy Entry/Exit feature has been modified in the instrument cluster. In this modified feature, only the steering column will move. The seat will not move during Easy Entry/Exit activation. Also, the user can only select Easy Entry/Exit either "On" or "Off" in the instrument cluster display. New spare parts are also affected by this change. Please ensure the instrument cluster installed in the vehicle has the capabilities of moving the seat in the Easy Entry/Exit mode.

NOTE: The following allowable labor operations should be used when submitting a warranty claim for this repair. This information has been generated on May 9, 2007. Please refer to Netstar -> Star TekInfo -> Star Time for the most current labor time allowance.
