- N10/1 (Driver-side SAM control unit with fuse and relay module)
- N10/1kL (Starter relay)
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 N10/1kL (Starter relay).
- Measurement is performed at the contact slot of component N10/1kL (Starter relay).
- Measure resistance with multimeter between socket (F.44) 14 of the 35-pole socket box tester and socket (N10/1kL) 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 N10/1kL (Starter 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
