1995 ACURA TL Service Repair Manual

Diagnostic Trouble Code (DTC)

DTC Erasure

1. Pull the parking brake lever up.

2. Push and hold the TCS switch, then turn the ignition switch ON (II).

3. Hold the TCS switch pushed for four seconds (do not release the TCS switch), then release the TCS switch for less than

six seconds.

4. After three seconds, the TCS indicator light go off three times, then turn it on. It means that the DTC is erased.

NOTE:

• Follow these steps exactly. If you connect the SCS service connector and/or release the parking brake lever during

these steps, the DTC will not be erased.

• If the TCS indicator light blinks repeatedly, replace the TCS control unit.
