[NEW] designates changes to this revision
SUBJECT
Doors Will Not Unlock with the Remote or Central Locking Switch
MODEL
E83 (X3) equipped with the Ambient Light Package (SA 563) and produced from 9/9/2007 [NEW] - 6/6/08
SITUATION
Intermittently, the doors will not unlock when pressing the unlock button on the remote, or when pressing the central locking switch.
[NEW] In some cases, the vehicle can be unlocked by pressing the unlock button a second time.
[NEW] In other cases, the servomotor in the latch has failed and as such, the unlock function is not restored. When this occurs, the vehicle can still be entered by using the key in the lock cylinder, or exited by pulling the interior door handle twice.
No relevant fault codes are stored in the General Module (GM5).
CAUSE
Software error in the GM5
[NEW] PROCEDURE
- If the problem is intermittent, do not replace any parts or program and/or code the vehicle, as this will not provide a solution.
- If any of the door latches are permanently inoperative, those latches must be replaced before proceeding.
- Refer to SI B61 17 08, "Service Action: Reprogram General Module", for complete details on how to update the GM5 software and permanently correct the problem.
