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. The electronic brake control module utilises this signal to calculate the driver intended driving direction.
Conditions for Running the DTC
| • | Vehicle speed is greater than 15 km/h (10 MPH). |
Conditions for Setting the DTC
C0710 00 or C0710 11
| • | The steering wheel angle sensor fails internally. |
| • | The steering wheel alignment may be out of the specified range. |
| • | The steering wheel angle sensor may not be properly mounted. |
C0710 09
The steering wheel angle sensor detects an error of 30° or more.
C0710 0A
The steering wheel angle sensor signal does not vary.
C0710 18
The steering wheel angle sensor signal has a low amplitude signal.
C0710 19
The steering wheel angle sensor signal has a high amplitude signal or greater value than physically possible.
C0710 4B
The steering wheel angle sensor is not calibrated or learned.
Action Taken When the DTC Sets
| • | The traction control/stability control-active indicator turns ON. |
| • | The electronic brake control module disables the traction control and the vehicle stability control for the duration of the ignition cycle. |
Conditions for Clearing the DTC
| • | In order for the DTC to clear the electronic stability control system must be initialised. Perform the steps listed below to initialise the system: |
| 1. | Vehicle OFF, open the driver door and remove all keyless entry transmitters from the vehicle and secure in a place outside the vehicle. |
| 2. | Close the driver door and let the vehicle sit for 3 minutes. |
| 3. | Vehicle ON, leave the vehicle in Park for greater than 10 seconds. |
| 4. | Drive the vehicle in a straight line at a speed greater than 32 km/h (20 mph) for 30 seconds. |
| • | The condition for setting the DTC is no longer present. |
| • | The history DTC will clear after 40 consecutive fault-free drive cycles have occurred. |
Diagnostic Aids
| • | Confirm that all tyres are of the proper size and that all are matching brands. Check and adjust all tyres to the stated cold air pressure as identified on the tyre placard. If a mis-sized or non-matching brand tyre is present, inform the customer that in order for the vehicle stability enhanced system to function normally, tyres need to be a uniform size and rolling diameter. |
| • | 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. |
| • | Improperly mounted or loose sensor. |

Circuit/System Verification
- Vehicle in Service Mode.
- Verify none of the DTCs listed below are set:
| ⇒ | If any of the DTCs are set |
| ⇓ | If none of the DTCs are set |
- Verify that DTC C0186, C0196, or C0287 is not set.
| ⇒ | If any of the DTCs are set |
| ⇓ | If none of the DTCs are set |
- Verify that DTC C0710 4B is not set.
| ⇓ | If DTC C0710 4B is not set |
- Verify the B99 steering wheel angle sensor is installed correctly.
| ⇒ | If loose or incorrect installation |
| | Correct the installation of the component. |
- Refer to Circuit/System Testing.
Circuit/System Testing
- Vehicle 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.
- Test for less than 10 Ω between the ground circuit terminal 6 and ground.
| 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. |
- Vehicle in Service Mode.
- Verify a test lamp illuminates between the ignition circuit terminal 5 and ground.
| ⇒ | If the test lamp does not illuminate |
| 4.1. | Vehicle 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. |
| 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.
- Verify that DTC C0710 does not set while operating the vehicle under the Conditions for Running the DTC.
| | Replace the K17 electronic brake control module. |
| ⇓ | If the DTC does not set |
- All OK.
