DTC Descriptors
DTC C0710 00
- Steering Wheel Angle Signal Malfunction
DTC C0710 42
- Steering Wheel Angle Signal Calibration Not Programmed
DTC C0710 5A
- Steering Wheel Angle Signal Not Plausible
DTC C0710 71
- Steering Wheel Angle Signal Invalid Data
Diagnostic Fault Information
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 messages from the steering wheel angle sensor identifying the position and direction of the steering wheel. The 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 00
The steering wheel angle sensor signal is invalid.
C0710 42
The steering wheel angle sensor is not calibrated.
C0710 5A
* The steering wheel angle sensor offset is out of the specified range.
* The steering wheel angle sensor signal is out of the specified range.
C0710 71
* A short to voltage or open/high resistance is detected in the steering wheel angle sensor ground circuit.
* A short to ground or open/high resistance is detected in the steering wheel angle sensor ignition circuit.
* The steering wheel angle sensor signal is not plausible with the yaw rate sensor signal and lateral acceleration sensor signal.
Action Taken When the DTC Sets
* The traction control/stability control-active indicator turns ON.
* The electronic brake control module disables the stability control for the duration of the ignition cycle.
Conditions for Clearing the DTC
* The DTC clears when the diagnostic runs and passes.
* The history DTC will clear after 40 consecutive fault-free drive cycles have occurred.
* The electronic brake control module will turn off the indicator with the next ignition cycle.
Diagnostic Aids
* Improperly mounted or loose sensor steering wheel angle sensor.
* Check and adjust all tires to the stated cold air pressure as identified on the tire placard.
* 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.
* Confirm that all tires are of the proper size and matching brands. 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.

Circuit/System Verification
1. Ignition ON.
2. Verify the scan tool Steering Wheel Position parameter corresponds to the actual steering wheel position as the steering wheel is turned through its entire range of motion.
• If the parameter does not correspond with the steering wheel position or the reading is erratic
Refer to Circuit/System Testing.
• If the parameter reading corresponds with the steering wheel position
3. All OK.
Circuit/System Testing
1. Ignition ON.
2. Verify DTC C0710 4B or C0710 5A is not set.
• If either DTC is set
Perform the Steering Angle Sensor Centering Procedures.
• If either DTC is not set
3. 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.
4. Test for less than 10 ohm between the ground circuit terminal 6 and ground.
• If 10 ohm or greater
1. Ignition OFF.
2. Test for less than 2 ohm in the ground circuit end to end.
• If 2 ohm or greater, repair the open/high resistance in the circuit.
• If less than 2 ohm, repair the open/high resistance in the ground connection.
• If less than 10 ohm
Note: With the B99 steering wheel angle sensor disconnected, the electronic brake control module should supply ignition voltage to the sensor for 3 - 5 seconds once the ignition is turned ON.
5. Ignition ON.
6. Verify a test lamp illuminates between the ignition circuit terminal 5 and ground.
• If the test lamp does not illuminate
1. Ignition OFF, disconnect the harness connector at the K17 electronic brake control module.
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
3. Test for less than 2 ohm in the ignition circuit end to end.
• If 2 ohm or greater, repair the open/high resistance in the circuit.
• If less than 2 ohm, replace the K17 electronic brake control module.
• If the test lamp illuminates
7. Replace the B99 steering wheel angle sensor.
8. Verify the DTC does not set while operating the vehicle under the Conditions for Running the DTC.
• If the DTC sets
Replace the K17 electronic brake control module.
• If the DTC does not set
9. All OK.
