Hello.
We've assisted a customer whose experienced any manner of issues with his Ducato motorhome, washer pump, headlights, windscreen wipers and headlights all acting of their own accord. The fault was isolated to a failed BCM, which is now discontinued and we were guided to a chap that specialises in data transfers between BCM's amongst other modules.
We removed the old module, and there were no water ingress issues on the connections that could have led to the problem. With the part number of the BCM confirmed to what's on Fiat's system, our customer sourced a used one and the third party successfully completed a data transfer without any issues noted and the unit returned.
We fitted the replacement unit and all of the customers issues we're resolved. I must add at this point that there was an ABS warning light present which our MES picked up as faults C1881 (Line (CAN) between ABS and injection control unit: no communication, C1103 (Factory/service final self check/calibration) and C1100( No end of line configuration). The customer had made arrangements with his MOT centre to investigate the ABS light and perform the MOT. This remained though the Odo was flashing indicating a Proxi Realignment was required. Their diagnostics software picked up saying that the BCM was not coded correctly and that there was an incorrect module for variant.
We've checked our MES scan to check that the ISO codes and software revisions all marry up between the pre and post BCM swap and they do. We're now a little lost what could be wrong, i.e. could the replacement used BCM be faulty, could there be an issue in the ABS system that isn't allowing the Proxi Alignment to take place and can we turn off the ABS system with MES and could that allow the alignment to take place.
Any thoughts would be welcomed, as given these BCM's are NLA if problems can't be resolved then the vehicle is no longer road worthy. We've been approached by another customer whose got issues with his headlights whose garage is indicating that they've checked everything and all that's left is the BCM, plus they have had other issues that would relate back to a BCM fault. They spoke to Fiat who didn't seem all that surprised to hear of the issue.
Thanks.
