### DTC Descriptor

DTC C0460 00: Replace Steering Angle Sensor
DTC C0460 12: Steering Angle Sensor Circuit Range/Performance
DTC C0460 42: Steering Angle Sensor Not Calibrated
DTC C0460 71: Steering Angle Sensor Invalid Signal
DTC C0460 5A: Steering Angle Sensor Plausibility Error

### Circuit/System Description

The steering wheel position sensor supplies 2 analog inputs, Phase A and Phase B, to the electronic brake control module (EBCM). The 2 input signals are approximately 90 degrees out of phase. By interpreting the relationship between the 2 inputs, the EBCM can determine the position of the steering wheel and the direction of the steering wheel rotation.

### Conditions for Running the DTC

• | The ignition is ON.

• | Ignition voltage is greater than 8 volts.

• | The vehicle speed is less than 10 km/h (6.2 mph).

### Conditions for Setting the DTC

REQUIRED

### Action Taken When the DTC Sets

• | The EBCM disables the Electronic Stability Control (ESP)/Electronic Brake Distribution (EBD) for the duration of the ignition cycle.

• | The multi function display (MFD) displays the Stability Ctrl Off message.

### Conditions for Clearing the DTC

• | The condition for setting the DTC is no longer present.

• | The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

• | The DTC can be cleared using a scan tool.
