because so much has been affected it should in theory make it something like a maxi fuse or relay that controls many circuits, and in theory easier to find........
You would think so - but I'm having a 'mare wit this. None of the maxi fuses look to be a a problem - the earths I've managed to locate seem fine,
"Alternator voltage regulator . check the charge rate i had the same problem .
all sorted after i changed the regulator."
The alternator is charging at 14.12volts that sounds OK to me.
While trying to find relevant info in eLearn I found this:
"The following nodes are connected to the Body Computer M1 via the B-CAN:
climate control sytem control unit M70;
instrument panel E50;
radio or built-in radio-telephone-navigator P20 ;
controls unit on the driver''s door H44 ."
Other stuff (ABS, Steering sensor, engine management) all of which are working go throught the C-CAN.
That sounds like pretty much a list of most of the affected stuff - so the Body Control Module really has to stay near the top of the list of suspects.
But how do I isolate and test or work on the B-CAN? I can see what it does - but I don't really understand what it is!. Is it connected to the Body Computer? Is it part of the Body Computer? Does it exist physically or is it a "software thing" that organises those modules? If anyone can help me to understand this I'd be very thankful,
