Dodge Caravan BCM problem
1997 dodge caravan body control module shorting out
windshield wipers didn't work/changed bcm/wipers work/but led odometer reading not working/abs light stays on
Expert Troubleshooting Suggestion For This problem:
Remove the new BCM out and try fitting old BCM back in to see if the instrument cluster functions all come back. May be replacement BCM is bad and causing the cluster problems, but what you have going on with it is usually an internal cluster problem.
If the gauges and odometer don't work with the old BCM then the problem is most likely in the cluster.
On most of such cases its seen that solder joints will crack in the row of joints where the electrical connector terminals solder to the circuit board. Carefully resoldering these joints will usually take care of that problem without having to replace the circuit board.
The ABS light may be ON because of a communication issue. The cluster can take down the CCD bus communication network when it tries to find ground because of the cracked solder joints.
This will help.
Thanks.
