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 utilises this signal to calculate the driver intended driving direction.

Conditions for Running the DTC

•	The ignition is ON.

•	Ignition voltage is greater than 8 volts.

Conditions for Setting the DTC

C0710 4B

Steering Wheel Position Sensor not calibrated after installation.

C0710 5A

•	The steering angle sensor signal is out of specified range.

•	The steering angle sensor offset is out of specified range.

C0710 71

The steering angle sensor signal is not plausible with the yaw rate sensor signal and lateral acceleration sensor signal.

Action Taken When the DTC Sets

•	The EBCM disables the traction control system (TCS)/vehicle stability enhancement system (VSES) for the duration of the ignition cycle.

•	A warning indicator on the information display module may be displayed.

•	The ABS remains functional.

Conditions for Clearing the DTC

•	The condition for the DTC is no longer present.

•	The electronic brake control module (EBCM) clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles.

Diagnostic Aids

•	Inspect the vehicle for proper alignment. 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.

•	Possible causes for this DTC are the following conditions:

—	One of the steering wheel position sensor inputs are open, shorted to ground, or shorted to battery.

—	Internal steering angle sensor malfunction

—	Noise on the steering wheel position signal circuits

—	Yaw and lateral acceleration sensor malfunction causing drifting signal outputs

—	Internal EBCM malfunction

Circuit/System Verification

With the scan tool perform the Steering Angle Sensor Centering.
Verify the DTC does not reset.

Circuit/System Testing

Ignition OFF, disconnect the harness connector at the steering angle sensor.
Test for less than 1 ohm of resistance between the low reference circuit terminal 6 and ground.

⇒	If greater than the specified range, test for an open/high resistance in the ground circuit.

Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 5 and ground.

⇒	If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

Ignition OFF, disconnect the harness connector at the EBCM.
Ignition ON, test for 0 volts between the EBCM Bus-communication terminal 24 and ground.

⇒	If greater than the specified value, test the communication circuit for a short circuit to voltage.

Test for 0 volts between the EBCM Bus- communication circuit terminal 12 and ground.

⇒	If greater than the specified value, test the communication circuit for a short circuit to voltage.

Ignition OFF, test for infinite resistance between the EBCM Bus-communication circuit terminal 24 and ground.

⇒	If not the specified value, test the communication circuit for a short circuit to ground.

Test for infinite resistance between the EBCM Bus-communication circuit terminal 12 and ground.

⇒	If not the specified value, test the communication circuit for a short circuit to ground.

Test for less than 1 ohm of resistance between the EBCM communication circuit terminal 24 and Yaw/Lateral Accelerometer Sensor terminal 1.

⇒	If greater than the specified range, test the communication circuits for an open/high resistance.

Test for less than 1 ohm of resistance between the EBCM communication circuit terminal 12 and Yaw/Lateral Accelerometer terminal 3.

⇒	If greater than the specified range, test the communication circuits for an open/high resistance.

Test for infinite resistance between the EBCM communication circuit terminal 24 and terminal 12.

⇒	If not the specified value, test the communication circuits for a short circuit together.

If all circuits test normal, replace the steering wheel position sensor.
If the DTC is reset again after replacing steering wheel position, replace the EBCM.
