Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer Dodge. The error code 400.1 means that the battery was disconnected with the key in the run position. It should not be a cause for your problem. If your van has factory alarm, (which is in the BCM). then installing a BCM without factory alarm enabled (even though it is the same part #) will prevent a no start. Now you should be able to start the van by putting in the original BCM, opening the hood, and turning the lift gate lock to the unlock position. This should enable the alarm in the BCM. This is all under the assumption that your van has factory alarm, and that the original BCM is still good. If you are not sure if it is factory alarm, then send me your VIN # XXXXX I will look it up for you.
That's great! You can go ahead and ask me another question on this thread, but I may not be able to get back to you until I get home from work this evening,
