C5 X7, door sidepocket and doorhandle lights

[torneol]

Is it possible, that there is an issue with door harness in drivers side and that effects problems on the other side of a car?

[torneol]

When drivers door is open and I grap the harness, cetral locking gets activated. So there might be a bit problem with wires.

Does this cause passenger side mulfunctions?

[GiveMeABreak]

Yes it can as there are functions from the Driver's control pad that cross over to the passenger side like the mirrors and the windows, locking etc.

[torneol]

Ok, thanks for that info. I'll check that side too.

Here's the full diagram:

Is it so, that 6410 and 6415 are mirrors?

6410: driver's mirror (electric mirror / heated mirror)
6415: passenger mirror (electric mirror / heated mirror)

Is there any diagram available, where I can see, that which pin is which in door harness connector?

So I can open that connector between hinges and check, if there is any missing power there. Then I can be absolutely sure, that its not door harness fault.

Or what I should check next?

[GiveMeABreak]

Not really, because the loom enters via the bulkhead and through the door aperture before splitting off to the various modules - and which modules you have depends on your trim level and fitted options such as wing mirrors (Electrochrome, Heated, Indexable / Folded), seat / mirror / heating memorisation etc.) as the harness will differ depending on these options and build date.

The driver's door control panel (Front / Rear Window adjustment / child lock activation and mirror controls are on a different control unit to the memorisation / wing mirror circuit. So which one do you want?

As you've mentioned the door locking controls I'll put that one up shortly.

6202 : front left-hand door lock assembly
6207 : front right-hand door lock assembly

Wires
6203: Left-hand front lock locking + command
6205A: Left-hand front lock deadlocking + command (Note, you don't have Deadlocking on this vehicle - only Simple Locking)
M6202: EARTH m6202
6916: front left lock position information
6914: front left door open switch

I have no idea, what I want about those; all I want, that mirror and lights in the door works .

If door harness is ok, where I suppose to find fault next? If BSI or BSM doesn't suply power, where is this fault hiding? What I can check next?

[torneol]

Could it be a BSI fault? How can I ensure, that it's not?

[torneol]

Does the CANbus go through the mirror? So if the cable (CANbus) is broken inside the mirror, does it block other things to work at same bus?

[GiveMeABreak]

The mirror circuit (for your specific type of Memory Mirrors fitted) is on a separate diagram, (see below): The CAN Comfort High & Low and the LIN Data Bus are on the (6036) driver's door electric window/mirror control pad, which go to the BSI, with the LIN Data Bus (9046B) going over to the passenger side Mirror Memory unit (6404) which connects the 2 units.



The Central locking circuit is separate.

[torneol]

Ok, thanks for pains.

I think, that I don't have anymore recourses for this, so I let it be broken.

[torneol]

This problem is solved! Car was at repairshop and they invastigate it quite properly.

Faulty part, which arrenged these problems, was a tiny box inside the door. It's near the mirror, in upper corner of the door. Bitron BEM X7 CEM 00 in my case.

They changed it and now the mirror and all the lights at door works fine.

Really glad you got this sorted, and thanks for the feedback sharing how it was resolved
