- Inspect connector A at control unit N80 (Steering column module) for damage, correct connection, loose contact and corrosion and repair, if
necessary.
- Otherwise select further tests.
End of test
NO
The measurement value is not OK.Possible cause and remedy
- Line between component N80 (Steering column module) and component N10/1 (Driver-side SAM control unit with fuse and relay module)
- Z7/58 (Circuit 30 connector sleeve)
- Line between component N80 (Steering column module) and component W15/1 (Ground (right footwell))
- Z6 (Ground connector sleeve)
- N10/1 (Driver-side SAM control unit with fuse and relay module)
End of test
