B1710

Fault Symptom
TCS OFF lamp on, TCS system inoperative.

Condition
No engine rpm signal and car driven at speeds above 60 km/h.

Diagnostic Procedure

NOTE: If the tachometer does not work, the problem is probably a short circuit in one of the systems where the rpm signal is used.

1. With the engine running, check that engine speed is correct when ENGINE RPM is selected in the "OBTAIN READINGS" menu on the ISAT (scan tool).
If it is not, check the cable between pin 6 of the control menu and pin 43 of the MOTRONIC control module.
2. Clear the trouble code. Start the car and drive it to check whether the code is generated afresh.
- If it is then see preliminary diagnostic information.
