Warning Light That Door is Open

stemc · 05-21-2015, 03:35 AM

Hi guys, wondering if anyone can help me diagnose a problem.

I'm getting a warning light that the back passenger door is open and the overhead lights are coming on. The door is not open at all. The door locks ok with the fob. Seems to be the same door every time. I don't get the beeping on the motorway but as soon as I come into traffic it starts. Also the alarm will periodically go off when I'm in the house. Any suggestions? New lock needed or is it just some sensor issue in the lock itself?

Thanks in advance.

situation
The customer complains that while driving, a CCM (check control message) indicates the doors are open, even though they are closed. Also, sometimes the gong will sound and the interior lights will go on and off.

cause
Unspecified FRM door lock status due to voltage variations

correction
Program the vehicle with ISTA/P 3.55.3 or higher.

procedure
Perform diagnosis using ISTA/D and work through the corresponding test modules. Program and code the vehicle using ISTA/P 3.55.3 or higher.

New integration level: E89x-15-03-501 or higher

ONLY APPLIES TO E9x LCI
