PINPOINT TEST U: THE TRACTION ASSIST INDICATOR IS NEVER/ALWAYS ON


U1-U4:






U5:






Normal Operation
When the powertrain control module (PCM) senses a traction assist event is taking place, it sends the instrument cluster a message over the communication network to illuminate the traction assist indicator or to flash the traction assist indicator. The traction assist indicator informs the driver that a traction assist event is taking place, by flashing the indicator. It is also used to indicate a malfunction in the traction assist system, or if the traction assist control has been disabled by the operator, by illuminating the indicator constantly (not flashing).

Possible Causes
- traction assist system
- PCM
- instrument cluster
