B1376

Fault Symptom
TCS OFF lamp on, TCS system inoperative
Condition
Wheel speed signal incorrect or absent, or indicates a speed higher than 280 km/h.
NOTE: See under diagnostic trouble code B1371. B1371

Diagnostic Procedure
1. If the ANTI LOCK lamp also lights up, obtain readings of any trouble codes in the ADS system and take the necessary remedial action
2. Connect the ISAT (scan tool). Drive the car slowly (but at least 3 km/h) and select WHEEL SPEED FR in the "OBTAIN READINGS" menu to check whether wheel speed is displayed.
If it is not, connect a BOB and check whether a wheel speed signal is present on pin 7 when the RH front wheel is rotated at a speed of about 1/2 revolution per second. The correct reading is about 15 Hz.
If the reading is not correct, check the cable between pin 7 of the TCS control module and pin 7 of the ABS control module for continuity/ shorting.
3. Remedy any defective cable.
4. 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.
