2.2 turbo diesel 6sp lost communications with body control central junction box trying to find out info on control module hardware
car has got no ignition feed as keypad is locked in and no ignition lights
car also came up with a crash sensor fault which was able to be cleared and car restarted
after this we tried to install new firmware into body controller and since then the system shut down
trying to confirm if the module has failed and if it is a known problem fault code number:u2014

i would like some info on wiring diagrams
