Is there anyway to test the CCM?

Really only a fault code scan, have you checked fuse 14 in the dash side fuse board.

Tested all fuses for continuity and voltages, all are good

Hi Crasher, just wondering, the red/yellow wire from the CCM to the ESCL, is that supposed to have 12V or is that a ground.

Tested the wiring and it doesn't seem to have 12 V but if I do a volt test with battery positive and the red/yellow wire, the red/yellow wire is a ground.

Tested with both CCM and ESCL connected, disconnected, 1 module connected and a time and same results.

Sorry I am totally hopeless reading the wiring diagrams

Hi Mickeybo, engine code CFGB. My reg no. Probably will not help as the vehicle is registered in South Africa

Hi Crasher

Need help with voltages, from the CCM to the steering column lock there are 2 wires, red/yellow and green/brown.

Do you know what voltages these wires carry?

I'm assuming that the red/yellow is +12v and the green/brown is a ground?
