1.3. Guided test
Signal wire Open circuit
Special tools

- Test cable 266 589 01 63 00
- Socket box 129 589 00 21 00
Test sequence

- Switch off ignition.
- Connect 35-pole socket box at engine wiring harness.
- Remove relay N10/1kM (Starter circuit 50 relay).
- Measurement is performed at the contact slot of component N10/1kM (Starter circuit 50 relay).
- Measure resistance with multimeter between socket (F.32) 2 of the 35-pole socket box tester and socket (N10/1kM) 2
Specified value

- Resistor< 1,5ohms
Question

- Is the measurement value OK?


YES
The measurement value is OK.Possible cause and remedy

- In the event of stored faults with a high fault frequency count or in the event of customer complaints, check lines and connectors for loose contact and corrosion..
- Test relay N10/1kM (Starter circuit 50 relay), replace if necessary.
End of test

NO
The measurement value is not OK.Possible cause and remedy

- Test wiring/ plug connection.
End of test

1.4. Test relay N10/1kM (Starter circuit 50 relay).
Test prerequisite

- Power supply (circuit 30) is OK.
Note

- The terminal diagram can be opened using button F7.
Test sequence

- Unplug component N10/1kM (Starter circuit 50 relay) from component N10/1 (Front SAM control unit with fuse and relay module).
- Measure resistance with multimeter between pins (N10/2kM)30 and (N10/2kM) 87
Specified value

- Resistor: > 30kohms
Question

- Is the measurement value OK?

















YES
The measurement value is OK.Note

- The terminal diagram can be opened using button F7.
Test sequence

- Measure resistance with multimeter between pins (N10/2kM)30 and (N10/2kM) 87
- Connect terminal 85 of relay N10/1kM (Starter circuit 50 relay) with ground.
- Connect terminal 86 of relay N10/1kM (Starter circuit 50 relay) with plus.
Specified value

- Resistor: < 3ohms
Question

- Is the measurement value OK?













YES
The measurement value is OK.Possible cause and remedy

- Check all affected plugs, connectors and electrical components for damage, loose contact, corrosion etc. and repair if necessary.
- Component N10/1 (Front SAM control unit with fuse and relay module) is defective.
End of test

NO
The measurement value is not OK.Possible cause and remedy
