Tests AI: The Traction Control Reconfigurable Telltale Indicator Is Never/Always On

PINPOINT TEST AI: THE TRACTION CONTROL RECONFIGURABLE TELLTALE INDICATOR IS NEVER/ALWAYS ON

Normal Operation
The instrument cluster (IC) receives the traction control data from the ABS module over the high speed controller area network (HS-CAN) communication bus. The traction control reconfigurable telltale indicator flashes when the vehicle traction control is in active mode or is being controlled by the ABS module. The instrument cluster (IC) monitors the traction control message and when the ABS module detects a traction control concern, the instrument cluster (IC) illuminates the traction control reconfigurable telltale indicator. If the traction control message is missing for greater than 5 seconds, the instrument cluster (IC) sets DTC U0121 and defaults the traction control reconfigurable telltale indicator on.

This pinpoint test is intended to diagnose the following:
- Traction control concern
- Instrument cluster (IC)
