It looks like I may have a bad Body Processor Module (BPM) on my 2002 XJR and I’m in the process of getting one to replace it. For this -I’m told- I must get the device’s last three digits which are not found on the unit label’s part number, but rather it’s supposed to be located on the VCATS label inside the trunk by the spare tire. Well, unfortunately I can’t find any such label even with the spare removed. So, questions:
Was the label location changed for 2002?
Did Jaguar quit placing those labels for 2002?
Is this 3-digit information found in a different form or somewhere else in the 2002 car?
Could other 2002 California-sold XJR’s (exactly like mine) have different 3-digits?
Ultimately, do I necessarily need those three digits
I would much appreciate any help with this issue.
Just in case you wonder why am I doing this, well, the starter won’t crank, I have no interior lights, no trunk lock or trunk lights operation, etc. The starter relay coil needs a ground signal from the BPM to operate the contacts that will power the starter motor, but it’s not getting it and the opposite side of the coil has verified 12v, plus, the contacts do have power ready to go. Examining the Batt power diagram (ignition OFF) I can easily trace that all the failing circuits somehow depend on signal/status from the BPM. And, circuits that ARE working, such as the “puddle” red lamps at the doors’ bottom corners are ON because they do not depend on anything related to the BPM. Besides, several other people report the same symptoms and a BPM replacement took care of it.
Sorry for the length here.
I’d much appreciate any help with this, thank you.
