Test K: The Traction Control System Cannot Be Disabled
Pinpoint Test K: The Traction Control System Cannot Be DisabledRefer to Vehicle/Diagrams, Instrument Cluster for schematic and connector information.
Normal Operation
The traction control switch is hard wired to the instrument cluster, traction control system status is indicated by an indicator in the instrument cluster. When the driver deactivates the traction assist system, the instrument cluster sends a message to the PCM and the ABS module over the high-speed controller area network (HS-CAN) bus. The traction assist system will remain deactivated until the driver pushes the switch again or until the ignition switch is cycled.
The instrument cluster sends a reference voltage to the stability/traction control switch along circuit CCA15 (YE/GY). When the switch is pressed, the reference voltage is momentarily grounded through the switch along circuit GD116 (BK/VT).
^ DTC C1093 Traction Control Disable Switch Circuit Failure - DTC C1093 will be set if the stability/traction control switch is pressed for more than 2 minutes during normal operation, is pressed at all during the instrument cluster on-demand self test or if there is an open circuit, a short to voltage or a short.
This pinpoint test is intended to diagnose the following:
^ Wiring, terminals or connectors
^ Traction control switch
^ Instrument cluster module
