Test Z: The Traction Control Indicator Is Never/Always On
PINPOINT TEST Z: THE TRACTION CONTROL INDICATOR IS NEVER/ALWAYS ONNormal Operation
The traction control indicator informs the driver that a traction control event is taking place, by flashing the indicator. It is also used to indicate a traction control system concern by illuminating the indicator constantly (not flashing). The instrument cluster (IC) receives the traction control signal from the ABS module through the communication network. When a traction control event is taking place, the ABS module sends a message to the instrument cluster (IC) over the communication network to flash the traction control indicator. When a traction control system concern exists, the ABS module sends a message to the instrument cluster (IC) to turn on the traction control indicator.
This pinpoint test is intended to diagnose the following:
- ABS module
- Instrument cluster (IC)
