PINPOINT TEST AH: THE TRACTION CONTROL DISPLAY IS NEVER/ALWAYS ON

Test AH1-AH2:

Normal Operation
The traction control display is an output signal that is controlled by the anti-lock brake system/traction control/stability assist (ABS/TC/stability assist) module. The ABS/TC/stability assist module communicates the traction control status to the instrument cluster over the SCP network. The message center uses that information to display the traction control message.

Possible Causes
- ABS/TC/stability assist system module
- instrument cluster
