Traction Control Indicator

During initialization, the instrument cluster receives the traction control system state status message from the traction control module to determine if the vehicle is equipped with traction control. If the vehicle is equipped with traction control, this information is stored in random access memory (RAM) and the indicator proves out for 3 seconds during each ignition cycle. If this message is not received, the instrument cluster assumes that the vehicle is not traction control equipped and the indicator remains off. When the traction control is active, the traction control module sends the instrument cluster a traction control active signal and the instrument cluster illuminates the traction control indicator. When the traction control is inactive, the traction control module removes the traction control active signal and the instrument cluster turns off the indicator.

In the event of a traction control failure, the traction control indicator remains off and the ABS indicator illuminates.
