Diagnostic Instructions
* Perform the Diagnostic System Check - Vehicle (Initial Inspection and Diagnostic Overview) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Initial Inspection and Diagnostic Overview) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Initial Inspection and Diagnostic Overview) provides an overview of each diagnostic category.
DTC Descriptors
DTC C0710 00
- Steering Position Signal
DTC C0710 5A
- Steering Position Signal Plausibility Failure
Diagnostic Fault Information
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
The engine is running.
Conditions for Setting the DTC
C0710 00
* Open or short to ground on the ignition voltage circuit
* Open, short to ground, or short to voltage on the low reference circuit
C0710 5A
* The calculated steering angle does not correlate between the steering angle sensor and the yaw rate sensor.
* The steering wheel is off-center.
Action Taken When the DTC Sets
* The EBCM disables the VSES for the duration of the ignition cycle.
* A DIC message and/or a warning indicator may be displayed.
Conditions for Clearing the DTC
* The condition for the DTC is no longer present.
* The EBCM clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
* Run vehicle faster than 9.3mph xxx to clear DTC
Diagnostic Aids
The car should not pull in either direction causing the steering wheel to be off-center while driving straight on a level surface.

Circuit/System Verification
1. With the scan tool perform the Steering Angle Sensor Centering.
2. Operate the vehicle within the Conditions for Running the DTC. Verify the DTC does not reset.
Circuit/System Testing
1. Verify that DTC U2100, or U2142 are not set.
• If the DTC U2100, or U2142 are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (Diagnostic Trouble Code Descriptions)
2. 2. Verify the Yaw rate sensor and steering angle sensor mounting position is correct.
3. Ignition OFF, disconnect the harness connector at the steering angle sensor.
4. Ignition OFF for 60 seconds, test for less than 5 ohms between the low reference circuit terminal 6 and ground.
• If greater than the specified range, test the low reference circuit for an open/high resistance.
5. Ignition ON, test for ignition voltage between the ignition voltage circuit terminal 5 and ground.
• If not within the specified range, test the ignition voltage circuit for a short to ground or open/high resistance.
6. Ignition OFF, disconnect the harness connector at the EBCM.
7. Ignition ON, test for less than 1 volt between the following terminal listed below and ground.
* CAN Bus High serial data circuit terminal 37
* CAN Bus Low serial data circuit terminal 24
• If greater than the specified value, test the appropriate serial data circuit for a short to voltage.
8. Ignition OFF, test for infinite resistance between the following terminal listed below and ground.
* CAN Bus High serial data circuit terminal 37
* CAN Bus Low serial data circuit terminal 24
• If not the specified value, test the appropriate serial data circuit for a short to ground.
9. Test for less than 2 ohms between the appropriate serial data circuit terminals listed below.
* CAN Bus High serial data circuit terminal 37 at the EBCM harness connector and terminal 3 at the steering angle sensor harness connector.
* CAN Bus Low serial data circuit terminal 24 at the EBCM harness connector and terminal 1 at the steering angle sensor harness connector.
• If greater than the specified range, test the appropriate serial data circuit for an open/high resistance.
10. Test for infinite resistance between the CAN Bus High serial data circuit terminal 37 and the CAN Bus Low serial data circuit terminal 24.
• If not the specified value, repair the serial data circuits for a short together.
11. If all circuits test normal, test or replace the steering angle sensor. If DTC resets, replace the EBCM
Repair Instructions
Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
* Steering Wheel Position Sensor Replacement (Steering Wheel Position Sensor Replacement)
* Control Module References (Programming and Relearning) for EBCM replacement, setup, and programming
