Hi,
I have a 2013 Custom, i recently had the engine out to replace the head and have since refitted. Nothing changed other than a new head. When we done this we obviously disconnected the battery.. however.. i didn't know at the time the van has two batteries connected in series. The second battery was not disconnected.
Anyway, moving on..... before the work the van worked great, no dashboard lights at all. Since replacing the engine the van all started and ran perfectly however i now have an airbag light on the dash... i have checked all cables under the driver seat and they are all fine just in case i caught one when disconnecting the battery, it also comes up with a parking assistance issue when you turn the van on and the emergency service function is no longer available.
I have an Autel scanner and have scanned the van, various issues, ABS, BCM, Parking etc. When looking deeper into the BCM issues there are around a dozen faults, brake switch, crash data, restraints, ABD to name but a few, also a few that say ground Earth fault. Its also worth mentioning the key fobs no longer lock / unlock the van but the Immobiliser is working fine as the van starts and runs.
I have tried clearing the crash data but the Autel comes up with a communication error.
Having googled the issues A LOT.. i am starting to think the issue is with the BCM itself and may need replacing.. however before i go down that rabbit hole i want to ask the community if they have any thoughts.
Anyone with the right experience in using a scanner ( i use mine to just clear faults, more than that i have no idea ) would be helpful, i'm based on the outskirts of Leicester, obviously happy to pay. Unfortunately i cant drive to you as the van is SORN and needs an MOT... hence the Airbag light being an issue.
