PINPOINT TEST U: THE TRACTION CONTROL AND ADVANCE TRACTION CONTROL INDICATORS ARE NEVER/ALWAYS ON

Test U1-U3:

Normal Operation
The traction control status is monitored by the anti-lock brake system/traction control/integrated vehicle dynamics (ABS/TC/IVD) or ABS/TC module. When the traction control is in active mode, a traction active status message is sent to the instrument cluster from the ABS/TC/IVD or ABS/TC module over the standard corporate protocol (SCP) network, circuits 4-EG8 (GY/VT) and 5-EG8 (BU/WH).

Possible Causes
- ABS/TC/IVD or ABS/TC module
- instrument cluster
