Special tool

- Adapter cable220 589 00 99 37
Test prerequisite

- The actual value is not o.k.
Test sequence

- Switch on ignition.
- Detach coupling at component S43x1 (Oil level indicator switch connector).
- Connect adapter cable no. 220 589 00 99 37 to engine wiring harness S43 (Oil level indicator switch).
- Measure direct voltage with multimeter between ground socket and socket (S43x1) 2
Specified value

- Voltage[11...14] V
Question

- Is the measurement value OK?







YES
The measurement value is OK.Check oil level with dipstick with engine switched off, adjust to correct level if necessary.Continue with button F2

Test 1.1: The oil level was too low.

Test 1.2: The oil level was too high.

Test 1.3: The oil level was OK.

1.1. The oil level was too low.
Refill engine oil. End of test

1.2. The oil level was too high.
Drain engine oil.End of test

1.3. The oil level was OK.
Test signal line between components S43 (Oil level indicator switch) and N3/9 (CDI control unit) for Open circuit in wiring.

Test prerequisite

- The engine oil level is OK.
Important note

- The value INSUFFICIENT is displayed in the event of open circuit in the wiring.
Test sequence

- Switch off ignition.
- Connect socket box (126-pin) to component N3/9 (CDI control unit).
- Detach coupling at component S43 (Oil level indicator switch).
- Connect adapter cable no. 220 589 00 99 37 to engine wiring harness S43 (Oil level indicator switch).
- Measure resistance with multimeter between socket (M.40) 40 of the 126-pole socket box tester and socket (S43x1) 2
Specified value

- Resistor< 1.0ohms
Question

- Is the measurement value OK?







YES
The measurement value is OK.Further procedure

- Test component S43 (Oil level indicator switch) for open circuit.
End of test

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

- Check lines and plug connection on components S43 (Oil level indicator switch) and N3/9 (CDI control unit) for loose contacts, damages, interruptions, etc. and if necessary, repair or replace parts.
End of test

NO
The measurement value is not OK.Check lines and plug connection on components S43 (Oil level indicator switch) and N3/9 (CDI control unit) for loose contacts, damages, interruptions, etc. and if necessary, repair or replace parts.End of test
