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 a ignition voltage from the electronic brake control module. The electronic brake control module 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 electronic brake control module 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 electronic brake control module disables the stability control for the duration of the ignition cycle.
- The traction control/stability control-active indicator turns ON.
- A driver information center message and/or a warning indicator may be displayed.

Conditions for Clearing the DTC

- A current DTC clears when the diagnostic runs and passes.
- The electronic brake control module will turn OFF the indicator in the next ignition cycle.
- The electronic brake control module clears the history DTC when a current DTC is not detected in 40 consecutive ignition cycles.

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

1. Ignition ON, verify that DTC C056D or C056E is not set.
2. Verify that DTC C0710 42 is not set.
3. Inspect the B99 steering wheel angle sensor for correct installation.
4. Ignition ON, observe the scan tool Steering Column Position parameter while turning the steering wheel. The reading should change between -550° and +550°.
5. All OK.

Circuit/System Testing

1. Ignition OFF and all vehicle systems OFF, 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.
2. Test for less than 5 ohms between the ground circuit terminal 6 and ground.
2.1. Ignition OFF
2.2. Test for less than 2 ohms in the ground circuit end to end.
3. Ignition ON.
4. Verify a test lamp illuminates between the ignition circuit terminal 5 and ground.
4.1. Ignition OFF, disconnect the harness connector at the electronic brake control module.
4.2. Test for infinite resistance between the ignition circuit and ground.
4.3. Test for less than 2 ohms in the ignition circuit end to end.
5. If all circuits test normal, replace the B99 steering wheel angle sensor.
6. Operate the vehicle according to the Conditions for Setting the DTC. The DTC should not set.
7. All OK.

Repair Instructions
