Pinpoint Test P: The Stability-Traction Control System is Inoperative or Cannot be Disabled: Notes
Normal Operation and Fault Conditions
The stability-traction control switch is a normally open switch. When the switch is pressed, the IPC senses ground through the switch and sends a message to the ABS module along the HS-CAN to disable the stability-traction control system. The IPC also illuminates the traction control OFF indicator.
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 AdvanceTrac ® always on 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 Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C2775 | TC / AYC ON / OFF Switch Stuck Failure | This DTC sets during the key cycle if the IPC senses a short to ground on stability-traction control switch circuit, if the stability-traction control switch is pressed for longer than 30 seconds or if the stability-traction control switch is pressed during the on-demand self-test. |
Possible Causes
- MyKey ® restricted key in use
- Wiring, terminals or connectors
- Network communication concern
- Stability-traction control switch
- IPC
