U0122 and ABS sensor
Had a fault on the way home which caused the following:
No ABS/DSC
No HDC
No Suspension
No Terrain Response
No Speedo
Had U0122 (Lost Communication With Vehicle Dynamics Control Module) and an ABSSensor on LHR (passenger rear) either open or short circuit, can't remember which.
So I guess I need to check continuity between the connectors at the front under the wheel arch and at the rear where it splits....but has anyone got any more info than this?
Wire colours/numbers, connector locations or anything else I can check?

Have tried moving sensors from side to side and the fault stays on the left hand side, have inspected the looms at either end and can't find and corrosion on the wires or connectors.....
Anyone else got any ideas on this one?

Allan sent me the diagrams and pictures, which was helpful in seeing where everything was but with limited time I haven't been able to find anything today so it's off to the Indi on Monday.
Unfortunately I don't have the time or the inclination (when its been 3*c outside all day) to spend hours around with it
Thanks for the diagram Robbie 2014 D4 XS

Had that all to bits, cleaned the wiring looms/connectors up as they were covered in mud.
No signs of corrosion or rubbing on either end of the connectors where it comes out of the copex to the connector block.

Normally, you will find the damaged wire about 3-4 inches from the connector, on the chassis side. More often than not, it will be hidden under the plastic conduitMy D3 Build Thread
