DTC Descriptor
DTC C0710 42
-
Steering Position Signal Calibration Not Programmed
DTC C0710 5A
-
Steering Position Signal Not Plausible
DTC C0710 71
-
Steering Position Signal Invalid Data
Diagnostic Fault Information
Circuit/System Description
The steering wheel angle sensor receives ignition voltage from the electronic brake control module. The electronic brake control module receives serial data message inputs from the steering wheel angle sensor identifying the position and direction of the steering wheel rotation. It utilizes this signal to calculate the driver intended driving direction.
Conditions for Running the DTC
Ignition ON.
Conditions for Setting the DTC
C0710 42
The steering wheel angle sensor is not calibrated.
C0710 5A
* The steering wheel angle sensor signal is out of specified range.
* The steering wheel angle sensor signal is not plausible with the yaw rate sensor and lateral acceleration sensor signal.
C0710 71
The steering wheel angle sensor signal is invalid.
Action Taken When the DTC Sets
* The traction control/stability control-active indicator turns ON.
* A driver information center message and/or a warning indicator may be displayed.
* The electronic brake control module disables the stability control for the duration of the ignition cycle.
Conditions for Clearing the DTC
* The DTC clears when the diagnostic runs and passes.
* The history DTC will clear after 40 consecutive fault-free ignition cycles have occurred.
Diagnostic Aids
* Improperly mounted or loose steering wheel angle sensor.
* 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.
* 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.

Circuit/System Verification
1. Ignition ON.
2. Verify the scan tool Steering Column Position parameter corresponds to the actual steering position as the steering wheel is turned through its entire range of motion between -500° and +500°.
• If the parameter does not correspond with the steering wheel position or the reading is erratic
Refer to Circuit/System Testing.
• If the parameter reading corresponds with the steering wheel position
3. All OK.
Circuit/System Testing
1. Ignition ON.
2. Verify that DTC C056D or C056E is not set.
• If either DTC is set
Refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.
• If none of the DTCs are not set
3. Verify that DTC C0710 42 is not set.
• If the DTC is set
Refer to Steering Angle Sensor Centering Procedures.
• If the DTC is not set
4. Verify the B99 steering wheel angle sensor is installed correctly.
• If loose or incorrect installation
Correct the installation or replace the component.
• If correct installation
5. Ignition OFF and all vehicle systems OFF with the scan tool disconnected, disconnect the harness connector at the B99 steering wheel angle sensor. It may take up to 2 minutes for all vehicle systems to power down.
6. Test for less than 10 ohms between the ground circuit terminal 6 and ground.
• If 10 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 10 ohms
7. Ignition ON.
8. Verify a test lamp illuminates between the ignition 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 ignition circuit and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance
3. Test tor less than 2 ohms in the ignition 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
9. Replace the B99 steering wheel angle sensor.
10. Ignition ON.
11. Verify that DTC C0710 is not set.
• If the DTC is set
Refer to Steering Angle Sensor Centering Procedures.
• If the DTC is not set
12. Verify the DTC does not set while operating the vehicle.
• If the DTC sets
Replace the K17 electronic brake control module.
• If the DTC does not set
13. All OK.
