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

Ignition ON.

Conditions for Setting the DTC

C0710 00

The steering angle sensor signal is invalid.

C0710 42

The steering angle sensor is not calibrated.

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 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 indicator in the next ignition cycle.

Diagnostic Aids

The car should not pull in either direction causing the steering wheel to be OFF centre while driving in a straight line on a level surface.

Circuit/System Verification

Ignition ON.
Verify the scan tool Steering Column Position parameter value constant change from -550 to +550° as the steering wheel is turned through its entire range from left to right.
If the parameter does not change

Perform the Steering Angle Sensor Centreing .

Refer to Circuit/System Testing.
If the parameter changes
All OK.

Circuit/System Testing

Ignition OFF all vehicle systems OFF. It may take up to 2 min for all vehicle systems to power down. Disconnect the harness connector at the B99 Steering Wheel Angle Sensor.
Test for less than 10 Ω between the ground circuit terminal 6 and ground.
If 10 Ω or greater

2.1.	Ignition OFF.

2.2.	Test for less than 2 Ω in the ground circuit end to end.

If 2 Ω or greater, repair the open/high resistance in the circuit.
If less than 2 Ω, repair the open/high resistance in the ground connection.
If less than 10 Ω
Ignition ON.
Verify that a test lamp illuminates between the ignition circuit terminal 5 and ground.
If the test lamp does not illuminate

4.1.	Ignition OFF disconnect the harness connector at the K17 Electronic Brake Control Module.

4.2.	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

4.3.	Test for less than 2 Ω in the ignition circuit end to end.

If 2 Ω or greater, repair the open/high resistance in the circuit.
If less than 2 Ω, replace the K17 Electronic Brake Control Module.
If the test lamp illuminates
Replace the B99 Steering Wheel Angle Sensor and verify the DTC does not reset.
If the DTC sets

Replace the K17 Electronic Brake Control Module.
If DTC does not set
All OK.
