Circuit/System Description
The steering wheel position sensor identifies the position of the steering wheel. The EBCM monitors the steering wheel position sensor phase A and phase B signal circuits for the VSES.
Conditions for Running the DTC
| • | Ignition voltage is greater than 10 volts. |
Conditions for Setting the DTC
| • | The EBCM detects the phase A and phase B signals do not correlate. |
| • | The EBCM detects the calculated steering angle from the steering wheel position sensor does not correlate with the steering angle calculated from the yaw rate. |
Action Taken When the DTC Sets
| • | The EBCM turns OFF the 5-volt reference circuit. |
| • | The EBCM disables the VSES for the duration of the ignition cycle. |
| • | A DIC message and/or a warning indicator may be displayed. |
Conditions for Clearing the DTC
| • | The condition for the DTC is no longer present. |
| • | The EBCM clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |
Diagnostic Aids
| • | If the steering wheel position sensor is disconnected, the EBCM will not provide 5-volts to the sensor. |
| • | A poor ground connection for the EBCM may cause this DTC to set. |

Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the steering wheel position sensor (SWPS).
- Ignition OFF for 60 seconds, test for less than 10 ohms between the low reference circuit terminal 2 and ground.
| ⇒ | If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the EBCM. |
- Disconnect the harness connector at the EBCM.
- Test for less than 1 volt between the 5-volt reference circuit terminal 1, and ground.
| ⇒ | If greater than the specified range, test the 5-volt reference circuit for a short to voltage. |
- Ignition OFF, test for infinite resistance between the 5 volt reference circuit terminal 1 and ground.
| ⇒ | If less than the specified value, test the 5 volt reference circuit for a short to ground. |
- Ignition OFF, test for less than 2 ohms between the 5 volt reference circuit terminal 1 at the steering wheel position sensor harness connector and terminal 25 at the EBCM harness connector.
| ⇒ | If greater than the specified range, test the 5 volt reference circuit for an open/high resistance. |
- Ignition ON, test for less than 1 volt between the signal circuits listed below and ground.
| • | Steering Wheel Position Signal A terminal 5 |
| • | Steering Wheel Position Signal B terminal 6 |
| ⇒ | If greater than the specified range, test the signal circuit for a short to voltage. |
- Ignition OFF, test for infinite resistance between the signal circuit listed below and ground.
| ⇒ | If less than the specified value, test the signal circuit for a short to ground. |
- Test for less than 2 ohms between the signal circuit terminals listed below.
| • | Signal A terminal 5 at the steering wheel position sensor harness connector and terminal 39 at the EBCM harness connector. |
| • | Signal B terminal 6 at the steering wheel position sensor harness connector and terminal 10 at the EBCM harness connector. |
| ⇒ | If greater than the specified range, test the signal circuit for an open/high resistance. |
- If all circuits test normal, replace the steering wheel position sensor. If the DTC resets replace the EBCM.
