### Circuit Description

The PCM monitors various parameters and will not allow traction control operation if any parameter falls outside a specified range.

### Conditions for Running the DTC

The ignition is ON.

### Conditions for Setting the DTC

The PCM diagnoses a condition preventing the engine control portion of the traction control function and sends a serial data message to the EBCM indicating that torque reduction is not allowed. The PCM will typically set a DTC and the EBCM will set this DTC.

### Action Taken When the DTC Sets

• | The EBCM disables the TCS until the DTC becomes a history DTC.

• | The Traction Off indicator turns ON.

• | The ABS remains functional.

### Conditions for Clearing the DTC

• | The condition for the DTC is no longer present and the DTC is cleared with a scan tool.

• | The electronic brake control module (EBCM) automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
