DTC Descriptor
DTC C0710 00 : Steering Position Signal
Circuit/System Description
The electronic brake control module (EBCM) receives CAN message inputs from the steering wheel position sensor identifying the position and direction of the steering wheel rotation.
Conditions for Running the DTC
• | Ignition voltage is greater than 9.5 volts. |
Conditions for Setting the DTC
• | Opens, short to ground, or short to voltage |
• | The calculated steering angle from the steering angle sensor does not correlate with the steering angle calculated from the yaw rate. |
Action Taken When the DTC Sets
• | The EBCM disables the vehicle stability enhancement system (VSES) for the duration of the ignition cycle. |
• | The driver information center (DIC) displays the Service Stability System message. |
• | The antilock brake system (ABS) remains functional. |
• | The VSES Caution indicator turns ON. |
Conditions for Clearing the DTC
• | The condition for the DTC is no longer present. |
• | The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |
Diagnostic Aids
• | During diagnosis, park the vehicle on a level surface. |
• | 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. |

Scan Tool Data List
Circuit/System Verification
- With the scan tool perform the Steering Angle Sensor Calibration.
- 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 ground circuit terminal 6 and ground.
⇒ | If greater than the specified range, test for an open/high resistance in the ground circuit. If the circuit tests normal, replace the EBCM. |
- Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 5 and ground.
⇒ | If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM. |
- Ignition OFF, disconnect the harness connector at the EBCM.
- Ignition ON, test for 0 volts between the communication circuit terminal 37 and ground.
⇒ | If greater than the specified value, test the communication circuit for a short to voltage. |
- Test for 0 volts between the communication circuit terminal 24 and ground.
⇒ | If greater than the specified value, test the communication circuit for a short to voltage. |
- Ignition OFF, test for infinite resistance between the communication circuit terminal 37 and ground.
⇒ | If not the specified value, test the communication circuit for a short to ground. |
- Test for infinite resistance between the communication circuit terminal 24 and ground.
⇒ | If not the specified value, test the communication circuit for a short to ground. |
- Test for less than 1 ohm of resistance between the communication circuit terminals 37 and terminal 3.
⇒ | If greater than the specified range, test the communication circuit for an open/high resistance. |
- Test for less than 1 ohm of resistance between the communication circuit terminals 24 and terminal 1.
⇒ | If greater than the specified range, test the communication circuit for an open/high resistance. |
- Test for infinite resistance between the communication circuit 37 and the communication circuit 24.
⇒ | If not the specified value, test the communication circuits for a short together. |
- If all circuits test normal, replace the steering angle sensor.
