J: the Traction Control Switch Indicator Is Never/Always on

Pinpoint Test J: The Traction Control Switch Indicator is

Test J1-J3:

Test J3-J5:

Test J5-J6:

Never/Always On

Normal Operation
The instrument cluster circuit 1412 (WH/PK) monitors for a ground (change of state). When the traction control switch is pressed momentary ground occurs through circuit 1205 (BK). The instrument cluster then sends a voltage to the traction control switch through circuit 939 (VT) illuminating the traction control switch and disabling the system.

Possible Causes
^ circuit 939 (VT) open or short to ground
^ circuit 1412 (WH/PK) open or short to ground
^ traction control switch
^ instrument cluster

CAUTION: Use the flex probe kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.
