Traction Control System (TCS) (NW7)

WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

When drive wheel slip is noted while the brake is not applied, the EBCM will enter traction control mode.

The EBCM requests the PCM to reduce the amount of torque to the drive wheels via serial data messages. The PCM reduces torque to the drive wheels by retarding spark timing and turning off fuel injectors. The PCM reports the amount torque delivered to the drive wheels via serial data messages.
