Manual check of supply voltage
Test prerequisite
- The fuses are OK.
- One of the fault codes 9010/9011 is present, or the associated actual value is not OK.
Test sequence
- Remove component N80 (Steering column module).
- Disconnect connector A at component N80 (Steering column module).
- Switch on ignition.
- Measure direct voltage with multimeter between sockets [N80] A.8 and [N80] A.9
Specified value
- Voltage [11.0...14.5] V
Question
- Is the measurement value OK?
YES
The measurement value is OK.Possible cause and remedy
- Inspect connector A at control unit N80 (Steering column module) for damage, correct connection, loose contact and corrosion and repair, if
