codes & wiring for mokka

[G1zm0]

hi .
there wasn't a section for opel/vauxhall

I have a 2023 mokka ultimate automatic.

It's an accident damaged one im fixing up.
I removed the dashboard and there was a few wires that I think are not connected (I checked around)

one was clipped on to the top windscreen part of the dash .and the other is down at the fusebox , attached to the side panel .

so after doing code read im getting following codes (unknown if related )

U121881 (built in systems interface)
U120581 (steering wheel angle sensor)

both below are special secured functions
B100355 (telematrix unit rtx or audio navigation)
B100355 (air-conditioning)

anyone have a wiring diagram of dashboard or know what these codes mean and how to clear?

I used a topscan to read codes

We do not support Vauxhall vehicles here, this is a French car Forum supporting mainly Citroen, Peugeot and DS Autos. Just because Vauxhall is part of the Stellantis group along with 12 other vehicle marques, that doesn't mean we support them and cannot provide parts or diagrams for them.

But generally speaking, your U codes are communication / network faults on the CAN network most likely. U1205 81 means there's a comms issue with the steering wheel angle sensor in the steering wheel control unit. The data is invalid and this will deactivate most safety features and functions of the ESP system. Suspects will be calibration, Steering wheel angle sensor itself, Suspension and wheels CAN or Intersystems CAN.

The U1218 81 fault is again referring to an issue with invalid data received by the BSI. Suspects areas include: Configuration of the Engine Management ECU, Configuration of the BSI, CAN, Electrical harness, Connectors.

Both the B1003 errors concern misconfiguration or invalid configuration or incorrect values of the Head Unit and A/C ECU. This may be because of the invalid data received caused by the previous faults already mentioned. That's about all I can help you with. Any ECU that is locked down will need dealer access to change or an account / paid access with Diagbox via purchased tokens.
