System Operation Check

Procedure

1. Place the front wheels on a chassis roller or jack up the front of the vehicle on level ground and support it on safety stands.

2. Start the engine, and verify that the TCS OFF light is out.

NOTE:
^ In order to protect the engine, if engine coolant temperature is extremely low, TCS control is temporarily interrupted until the engine coolant temperature rises. In such cases, the TCS OFF light illuminates.

3. If the TCS OFF light and TCS indicator light stay on after the engine is started, the TCS/ABS control module detects a failure. In that case, turn off the engine and follow the troubleshooting procedures.

4. Select D position.

5. Depress the accelerator pedal for 5 seconds, and verify that the engine speed is held low and that the TCS indicator light flashes.

NOTE:
^ If the front wheels rotate for 60 seconds or more, the ABS and TCS OFF lights illuminate, and the engine speed increases. In that case, the Warning light will not illuminate a second time when the ignition switch is at OFF then back to ON, and there will be no diagnostic trouble code entry made to the control module memory.

6. If not as described, follow the troubleshooting procedures.
