End of test

NO

The measurement values are not OK.Possible cause and remedy

- Check lines between components N73 (EIS [EZS] control unit) and N10/1 (Driver-side SAM control unit with fuse and relay module) and

repair or replace if necessary.

- Fuse and component F34 (Interior fuse box)

Continue with button F2

Possible cause and remedy

- Check component N10/1 (Driver-side SAM control unit with fuse and relay module).

Question

- Continue troubleshooting in control unit N10/1 (Driver-side SAM control unit with fuse and relay module)?

1.1.3.2.1.11. No further information available.

1.1.3.2.1.12. Check power supply at control unit N80 (Steering column module).

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

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
