Diagnostic Fault Information
Circuit/System Description
The steering angle sensor receives a 12 V reference voltage from the electronic brake control module (EBCM). The EBCM receives high speed controller area network (CAN) message inputs from the steering angle sensor identifying the position and direction of the steering wheel rotation. The EBCM utilizes this signal to calculate the driver intended driving direction.
Conditions for Running the DTC
Ignition ON
Conditions for Setting the DTC
C0460 71
The control module received an invalid steering angle sensor signal.
C0710 00
The steering angle sensor signal is invalid.
C0710 42
The steering angle sensor is not calibrated.
C0710 5A
* No steering angle sensor signal
* The steering angle sensor signal is not plausible with the yaw rate sensor signal.
* The steering angle sensor offset is out of specified range.
Action Taken When the DTC Sets
* The EBCM disables the stability control and hill start assist for the duration of the ignition cycle.
* The traction control/stability control-active indicator turns ON.
Conditions for Clearing the DTC
* A current DTC clears when the diagnostic runs and passes.
* The EBCM will turn OFF the indicator in the next ignition cycle.
Diagnostic Aids
The car should not pull in either direction causing the steering wheel to be OFF center while driving in a straight line on a level surface.

Circuit/System Verification
Ignition ON, observe the scan tool Steering Column Position parameter. As the steering wheel is turned, the reading should travel from -550 to +550°.
Circuit/System Testing
1. Ignition ON.
2. Verify that DTC C0710 42 or C0710 5A is not set.
• If any of the listed DTCs is set
Perform the Steering Angle Sensor Centering Procedures.
• If none of the listed DTCs is set
3. Inspect the B99 Steering Wheel Angle Sensor for correct installation.
• If loose or incorrect installation
Correct the installation of the component and perform the Steering Angle Sensor Centering Procedures.
• If installed correctly
4. Ignition OFF, disconnect the harness connector at the B99 Steering Wheel Angle Sensor.
5. Test for less than 5 ohms between the ground circuit terminal 6 and ground.
• If 5 ohms or greater
1. Ignition OFF.
2. Test for less than 2 ohms in the ground circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, repair the open/high resistance in the ground connection.
• If less than 5 ohms
6. Ignition ON.
7. Verify a test lamp illuminates between the 12 V reference circuit terminal 5 and ground.
• If the test lamp does not illuminate
1. Ignition OFF, disconnect the harness connector at the K17 Electronic Brake Control Module.
2. Test for infinite resistance between the 12 V reference circuit and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance.
3. Test for less than 2 ohms in the 12 V reference circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the K17 Electronic Brake Control Module.
• If the test lamp illuminates
8. Replace the B99 Steering Wheel Angle Sensor.
9. Ignition ON.
10. Verify the DTC does not set while operating the vehicle under the Conditions for Running the DTC.
• If the DTC sets
Replace the K17 Electronic Brake Control Module.
• If the DTC does not set
11. All OK.
