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
1.1.3.2.1.13. Check power supply at control unit Y3/8n4 (Fully integrated transmission control (VGS) control unit).
Operation number of operation texts and work units or standard texts and flat rates:27-0641Test prerequisite
- Battery voltage is OK.
- Fuse N10/1f46 (Fuse 46) in component N10/1 (Driver-side SAM control unit with fuse and relay module) is o.k.
Test sequence
- Switch off ignition.
- Separate plug connection at transmission.
- Measure voltage in transmission wiring harness using a multimeter.
