Asking for a friend who has just got a 2001 diesel, the door was dead when he purchased it just a week ago, the seller mentioned it's the out station maybe? Anywho...I'm helping him to fix up some of the minor issues it has, balljoints,exhaust, diesel leak etc but I'm no electrical genius and neither is he!
CDL doesn't work on this driver's door but will lock with the key, window and mirror also dead, nanocom won't work them either, all other doors are ok.
I've suggested we omit all 4 white kick panel plugs to at least take them out of the equation like I've done to mine. All fuses are good. Is there an obvious place to look that maybe feeds power to this door?
Door outstation. Everything on the door goes via that so if it dies, nothing on the door will work. Both are fed from the same fuses and don't go via the connections behind the kick panel. Easiest check is to swap it for the one on the passenger door and if the fault moves that is definitely the problem.
Cheers Richard, I knew you'd know!
I'll pass on your message and get him to sign up too.
Finally got around to swopping the door outstations, and the good front passenger door one swopped for the suspected driver's door one didn't work, everything still dead. It worked everything when fitted to the passenger door so both outstations are good.
To add.. interior light doesn't come on on the dead door either, fine on all the other doors. Is that a clue I wonder?
All that tells you is that the BeCM isn't seeing the signal from the door ajar switch in the latch. But as there is no communication between the BeCM and anything else in the door it makes sense that it doesn't work. If swapping the outstations hasn't proved a fault, then you need to check for power to the outstation on the Purple/Black wire on pin 10 at C1406 (16 way connector at the outstation furthest from the door hinges). There are two more connectors in the door jamb, which you'll need to pull the rubber conduit away from the door frame to get to which this power, along with all other wires between the outstation and BeCM, go through.
Champion, thanks again.
Knocked it on the head for now, cold, hungry and it's started to rain, his DMM is naffed too so I'll return tomorrow with mine.
Still not got round to this due to unforeseen issues. Just updating this thread so I don't appear rude 😉
OK, we've been fiddling and,again, run out of time to fully investigate the dead door but we have fixed the exhaust, abs sensor and dull message center.
What we have done also is swopped out his switch pack with my fully working one which has confirmed its not that causing his dead door but has confirmed that his sunroof switch needs sorting.
On the door, we got as far as checking voltages on the good door and comparing them at the plug for the electric window. All voltages checked out the same except for the yellow/red which was dead on the dead door but live on the good door. I'm not sure if it was a yellow with red trace or red with a yellow trace as the findings aren't here but in his glovebox. I found what I think is the other end into the becm but he was waiting to desperately leave to pick his daughter up.
So that's where we are at thus far.
