### Circuit/System Description

The electronic brake control module (EBCM) receives CAN message inputs from the steering wheel position sensor identifying the position and direction of the steering wheel rotation.

### Conditions for Running the DTC

• | Ignition ON.

• | Ignition voltage is greater than 10 volts.

### Conditions for Setting the DTC

#### C0460 00, C0460 12, C0460 5A, or C0460 71
