- Switch off ignition.
- Disconnect connector at component N15/5 (Electronic selector lever module control unit).
- Switch on ignition.
- [A.2] Measure direct voltage with multimeter between 2 and 1 [A.1]
Status of relevant actual value:
- Supply voltage (tml. 15):Warning! Communication with ECU required.
Specified value
- Voltage[7.0...16.0] V
Question
- Is the measurement value OK?
YES
The measurement value is OK.Possible cause and remedy
- Replace component Floor-mounted shift.
End of test
NO
The measurement value is not OK.Possible cause and remedy
- Check fuse f55 (voltage supply from control unit ESM) in component N10/1 (Front SAM control unit with fuse and relay module).
- Check all affected plugs, connectors and electrical components for damage, loose contact, corrosion etc. and repair if necessary.
End of test
