Diagnostic Fault Information
Circuit/System Description
The steering wheel 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 wheel 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.
* Vehicle speed is greater than 15 km/h (10 MPH).
Conditions for Setting the DTC
C0710 00
The steering wheel angle sensor offset is out of specified range after initialization.
C0710 09
The steering wheel angle sensor detects an error of 30° or more.
C0710 0A
The steering wheel angle sensor signal does not vary.
C0710 11
The steering wheel angle sensor is out of specified range.
C0710 18
The steering wheel angle sensor is not correlating with the yaw rate signal.
C0710 19
The steering wheel angle sensor signal has a greater value than physically possible.
C0710 4B
The steering wheel angle sensor is not calibrated or learned.
C0710 5A
The steering angle sensor signal is not plausible with the wheel speed sensor signals.
Action Taken When the DTC Sets
* The EBCM disables the traction control and stability control 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 indicators and enable the system functions in the next ignition cycle.
Diagnostic Aids
* Confirm that all tires are of the proper size and that all are matching brands. Check and adjust all tires to the stated cold air pressure as identified on the tire placard. If a mis-sized or non-matching brand tire is present, inform the customer that in order for the vehicle stability enhanced system to function normally, tires need to be a uniform size and rolling diameter.
* 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.
* Improperly mounted or loose sensor.

Circuit/System Verification
Ignition ON, observe the scan tool Steering Column Position parameter. As the steering wheel is turned, the reading should travel between -550 and 550°.
Circuit/System Testing
1. Ignition ON, verify that DTC C0035, C0040, C0045, or C0050 is not set.
• If the DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.
2. Ignition ON, verify that DTC C0186, C0196, and C0287 is not set.
• If the DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.
3. Ignition ON, verify that DTC C0710 4B is not present.
• If DTC is present, perform the Steering Angle Sensor Centering Procedures.
4. Inspect the B99 steering wheel angle sensor for correct installation.
• If loose or incorrect installation is diagnosed, correct the installation of the component.
5. Ignition OFF, disconnect the harness connector at the B99 steering wheel angle sensor.
6. Ignition OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down. Test for less than 10 ohm between the ground circuit terminal 6 and ground.
• If greater than the specified value, test the ground circuit for an open/high resistance.
7. Ignition ON, test for greater than 11 V between the 12 V reference circuit terminal 5 and ground.
• If less than the specified range, test the 12 V reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K17 EBCM.
8. If all circuits test normal, replace the B99 steering wheel angle sensor and verify the DTC does not reset. If the DTC resets, replace the K17 EBCM.
