Electrical Diagrams

[ARModen]

Does anyone have the electrical diagrams for a 2004 Turbo?  Specifically the steering column?  I have a faulty switch in the column, but I'm not at home with my tools.  I'd like to see if I can defeat the security switch in the column so I can drive home and replace the whole assembly.

Hope this helps.

Sorry, that's actually for the power adjustments.  This is a module under the column that locks the steering wheel in place when the car is turned off.  I found a good diagram for it, but I'm not seeing power on the supply side of the connector.  It seems to be powered from the driver identification control unit.  I need to locate this and see if there is power on the output to the column.  The motor and gearing that actually lock the wheel are good.  So it is either a fault on the board in the locking module, the control unit, or the wiring is broken somewhere.  Sadly there is pretty much no information out there on this part of the car.  The usual answer is replace it all at the dealership.  However, I'm not even sure which really expensive part needs replacing.  My local dealership is incompetent.  I'd end up paying them to easter egg around the car replacing anything they can get their hands on.

 

Does anyone know how to get at this driver control unit?  Is it the same as the keyless entry module?

This one shows the lock circuit.  Looks like power is supplied to the lock module by the KESSY unit (which you already know).  The unit itself apparently is located under the dash in the location shown and appears to be just to the left of the steering column (as you're looking forward).  Probably a b*itch to get to.

Yeah, the first one is the one I've been using.  The ELV A2 (supply) to A3 (ground) is reading 0VDC.  I think it should be ~12VDC when the key is in the ignition.  A1 (data) to ground is ~12VDC.  SO far I haven't actually found the kessy module.  The picture doesn't convey how many other things are in that general area.

 

I have a replacement column and the kessy modules are fairly cheap.  Perhaps I'll replace both and see if the dealer can get them programmed together.  But I'd feel a lot better if I can narrow it down to what specifically is wrong before I have it towed to the dealership.
