Hello,

I replaced the BCM in my 1998 Plymouth Grand Voyager with a used one from a salvage yard. As soon as we re-connected the battery, the alarm starting going off ( we did not even know the van had a security system as the alarm has never gone off and we do not have the keyless remote ) We have tried removing the IOD fuse for 3 minutes - also we have tried to turn the alarm off by locking and unlocking the drivers door with the key, and finally we tried placing the key in the lift gate in the unlock position and then in the ignition to off and on etc.. All things we have read on the internet. The van does start but will not stay started ( of course the alarm is constantly sounding), and as we were told by the salvage yard - the mileage did change when we replaced the BCm. Any ideas for us?

Thanks very much

Julie
