Test X: The Traction Assist Indicator Is Never/Always On
2007 Ford Edge FWD V6-3.5LSECTION Test X: The Traction Assist Indicator Is Never/Always On
PINPOINT TEST X: THE TRACTION ASSIST INDICATOR IS NEVER/ALWAYS ON
Normal Operation
The traction assist indicator flashes when the vehicle traction control is in active mode or is being controlled by the ABS module. The instrument cluster receives the traction control data from the ABS module over the high speed controller area network (HS-CAN) communication bus. The instrument cluster monitors the traction control message and when the ABS module detects a traction control concern, the instrument cluster illuminates the traction control reconfigurable telltale indicator. If the traction control message is missing for more than 5 seconds, the instrument cluster sets DTC U0121 in continuous memory and defaults the traction control reconfigurable telltale indicator on.
Possible Causes
- Traction assist system
- ABS module
- Instrument cluster
