Are there any TSBs specific to the BPM (body processor module)?
Or are there any How-To write-ups on diagnosing faults wit the BPM?
Is the BPM a semi common problem with these cars?
Found a previous forum thread with good BPM diag info
BTW, I found the following thread from 2018 where several knowledgeable folks from this forum were trying to help a guy with a similar issue before. Body processing module - 1996 XJ6
The info in this helped me work towards a solution to my problem.
I swapped out the BPM in my cart and after that I popped the top off of the original one. This turned out to be much more complex inside than I would have guessed.
TSBs or How-To articles on diagnosing the BPM?
