Body Control Module

[slash]

The BCM seems to be faulty on our 2003 CRD Grand Voyager. The rear doors won't open remotely, the switches on the B posts don't work. The overhead console functions are all not working either. Can the BCM be reprogrammed? Is this a Chrysler dealer job?

First off it's worth a try at removing the "IOD" fuse in the fuse box in the engine bay, left side wing (drivers side on LHD - of yours is of course!).

 

Leave it out for 20 to 30 minutes and it might just reset things for you!

 

Or disconnect the battery instead, or afterwards if the first doesn't work!

Yeah reset BCM by unpluging battery for 30min like @@bignev said.

1. Plug in Diagnostic tool. and read any codes.
