DTC Descriptor
DTC C0710 09
- Steering Angle Sensor Signal Rate of Change Above Threshold
DTC C0710 39
- Steering Angle Sensor Signal Internal Electronic Failure
DTC C0710 75
- Steering Angle Sensor Signal Above Allowable Range
DTC C0710 4B
- Steering Angle Sensor Signal Calibration not Learned
Circuit/System Description
The steering angle sensor measures the steering wheel position with 2 sensing inputs. It communicates the steering angle position and the steering angular velocity on the chassis CAN. The supervisor control module determines the state of health of the steering angle sensor based on the data the sensor is communication and other vehicle data that can be correlated.
Conditions for Running the DTC
C0710 09, 75 or 4B
The steering angle sensor signal rate of change above threshold.
* The ignition is ON.
* DTC C0561 71 is not set as a result of a steering angle sensor circuit or internal fault during the current ignition cycle.
C0710 39
The steering angle sensor signal rate of change above threshold.
* The ignition is ON.
* Stability control system is enabled and functioning without a current fault set.
* The power steering control module (PSCM) is functioning without a current fault set.
* The yaw rate sensor, lateral acceleration sensor, longitudinal acceleration sensor and steering angle sensor have not set a DTC during the current ignition cycle.
* The vehicle is driving at a speed greater than 6 meters/second (22 Km/h)
Conditions for Setting the DTC
C0710 09
The steering angle sensor signal rate of change above threshold.
C0710 4B
The steering angle sensor signal calibration not learned, or can not be learned.
C0710 39
The steering angle sensor signal internal electronic failure
C0710 75
The steering position signal above allowable range.
Action Taken When the DTC Sets
* The VSCM disables the vehicle stability enhancement system (VSES) for the duration of the ignition cycle.
* The driver information center (DIC) displays the SERVICE STABILITY SYS message.
* The ABS remains functional.
Diagnostic Aids
* During diagnosis, park the vehicle on a level surface.
* The car should not pull in either direction while driving straight on a level surface.
* The snapshot function on the scan tool can help find an intermittent DTC.

Circuit/System Verification
1. With the scan tool perform the Steering Angle Sensor Calibration.
2. Verify the DTC does not reset.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the steering angle sensor.
2. Test for less than 1 ohm between the ground circuit terminal 6 and ground.
• If greater than the specified range, test for an open/high resistance in the ground circuit.
3. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 5 and ground.
• If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
4. Ignition OFF, disconnect the harness connector X3 at the Vehicle Stability Control Module.
5. Ignition ON, test for 0 volts between the communication circuit terminal 72 and ground.
• If greater than the specified value, test the communication circuit for a short to voltage.
6. Test for 0 volts between the communication circuit terminal 52 and ground.
• If greater than the specified value, test the communication circuit for a short to voltage.
7. Ignition OFF, test for infinite resistance between the communication circuit terminal 72 and ground.
• If not the specified value, test the communication circuit for a short to ground.
8. Test for infinite resistance between the communication circuit terminal 52 and ground.
• If not the specified value, test the communication circuit for a short to ground.
9. Test for less than 1 ohm between the communication circuit terminals 72 and terminal 3.
• If greater than the specified range, test the communication circuit for an open/high resistance.
10. Test for less than 1 ohm between the communication circuit terminals 52 and terminal 1.
• If greater than the specified range, test the communication circuit for an open/high resistance.
11. Test for infinite resistance between the communication circuit 72 and the communication circuit 52.
• If not the specified value, test the communication circuits for a short together.
12. If all circuits test normal, replace the steering angle sensor.
