Pinpoint Test G: The Traction Control System Cannot Be Disabled: Notes
The traction control system can be disabled by pressing the traction control switch located on the instrument panel. When the system is disabled, the traction control system indicator in the instrument cluster will illuminate solidly.
The instrument cluster sends 5 volts to the traction control switch along circuit CCA15 (YE/GY). When the traction control switch is pressed, this voltage is sent through the switch and to ground along circuit GD116 (BK/VT).
When the instrument cluster receives input from the traction control switch, it will send a message over the high-speed controller area network (HS-CAN) bus to the ABS module disabling the traction control. The traction assist system will reset and return to normal operation when the ignition switch is cycled or when the switch is pressed and released a second time during the same ignition cycle.
- DTC C1093 Traction Control Disable Switch Circuit Failure - If the traction control switch closed for more than 2 minutes or if there is a short to ground on circuit CCA15 (YE/GY) during normal operation, DTC C1093 will be set. If the traction control switch closed during the instrument cluster self-test and for more than 2 minutes in during normal operation, DTC C1093 will be set.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Hazard/PAD/traction switch
- Instrument cluster

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
