Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Normal Operation and Fault Conditions
The stability-traction control disabled indicator (sliding car OFF icon) in the IPC provides traction control system status to the driver. When the driver presses the traction control switch, the FCIM sends a message to the GWM over the MS-CAN indicating the driver has requested the traction control to be disabled. The GWM relays this message to the ABS module over the HS-CAN2. The ABS module continues to monitor for excessive wheel spin, but no longer takes any action when a traction event is detected.
The ABS module then sends a message to the IPC through the GWM over the HS-CAN 3 to illuminate the stability-traction control disabled indicator (sliding car OFF icon).
The IPC responds by illuminating the stability-traction control disabled indicator (sliding car OFF icon). The traction control system remains deactivated until the driver changes the traction control state using the traction control switch or until the ignition is cycled.
If equipped, MyKey® allows users to configure traction control to be either always on or selectable. If a MyKey® restricted key is in use with the stability control feature configured to "on", the traction control system cannot be disabled. An admin key must be used to enable and disable the traction control system.
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C1109:64 | Vehicle Dynamic: Signal Plausibility Failure | Sets when the ABS module detects the traction control switch pressed in the applied position for longer than 10 seconds. This can be due to a wiring concern in the traction control circuit or an internal failure of the traction control switch. |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • 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.
