Special tools

- Test cable 271 589 00 63 00
- Socket box 129 589 00 21 00
Test prerequisite

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

- Switch off ignition.
- Connect 126-pole socket box at engine wiring harness.
- A4Observe oscilloscope pattern between sockets (1.88) 88 and (1.87) 87 of the 126-pole socket box testerA7
- Connect STAR DIAGNOSIS with special tool.
- Start measuring system.
Specified value:

- Resistance at 20° C coolant temperature
- [612...1255]ohms
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..
End of test

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

- Test cable from control module N3/9 (CDI control unit) (socket 1, pin 88) to component L5 (Crankshaft position sensor) (pin 2) for Open circuit.
- Test cable from control module N3/9 (CDI control unit) (socket 1, pin 87) to component L5 (Crankshaft position sensor) (pin 1) for Open circuit.
- Replace component L5 (Crankshaft position sensor).
