- Steering Position Signal Not Plausible

Diagnostic Fault Information






Circuit/System Description

The electronic brake control module (EBCM) supplies ignition voltage to the steering angle sensor and the yaw/lateral accelerometer sensor. The EBCM receives serial data messages from both the steering angle sensor and the yaw/lateral accelerometer sensor. The steering wheel speed position sensor is an input to the EBCM and provides the position of the steering wheel.

The steering wheel speed position sensor measures the steering wheel degree of rotation. The EBCM utilizes this signal to calculate the driver intended driving direction. The electronic brake control module (EBCM) receives CAN message inputs from the steering wheel speed position sensor identifying the position and direction of the steering wheel rotation.

Conditions for Running the DTC

The engine is running.

Conditions for Setting the DTC

C0710 00

* Open or short to ground on the ignition voltage circuit

* Open or short to voltage on the low reference circuit

C0710 5A

* The calculated steering angle does not correlate between the steering angle sensor and the yaw rate sensor.

* The steering wheel is off-center.

Action Taken When the DTC Sets

* A driver information center message and/or a warning indicator may be displayed.

* The EBCM disables the ABS, the traction control and the stability control for the duration of the ignition cycle.

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 40 consecutive drive cycles.

Note: During normal diagnostic and/or repair verification technicians may find that the ABS, Traction control and/or Stability control indicators may be ON with NO DTCs displayed by the EBCM. Do not replace the EBCM for this condition.

If the ABS, Traction control and/or Stability control indicators are ON with no DTCs set, perform the following steps:

1. Remove the key from the ignition, open and close the driver's door to turn off retained accessory power, and wait 60 seconds.

2. Ignition ON, if the ABS, Traction Control and/or Stability indicators are still illuminated, operate the vehicle at speeds greater than 16 km/h (10 MPH) to complete the self test. The EBCM should request all telltale indicators to turn OFF.

3. If the indicators remain ON with no DTCs set after the drive cycle, disconnect the battery for at least 60 seconds then reconnect the battery.

4. Operate the vehicle at speeds greater than 40 km/h (25 MPH), the EBCM should request all the indicators to turn OFF.

Diagnostic Aids

* Verify the steering wheel is properly installed.

* Verify the steering wheel speed position sensor is installed correctly.

* The car should not pull in either direction causing the steering wheel to be off-center while driving straight on a level surface.

* Inspect the steering column wiring harness for chafing, when the steering wheel telescoping feature is adjusted all the way in and the tilt is cycled up or down. The wires in the steering column harness may be chafed or cut on the tilt telescope mechanism edges.

Circuit/System Verification

1. Ignition ON.

2. Verify that DTC U2142 is not set.

If DTC U2142 is set
Refer DTC U2105-U2199 U2105.

If DTC U2142 is not set

3. Verify that DTC C0710 is not set.

If DTC C0710 is set
Refer to Circuit/System Testing.

If DTC C0710 is not set

4. Refer to Diagnostic Aids.

Circuit/System Testing

1. Ignition OFF and all vehicle systems OFF. Disconnect the harness connectors at the steering wheel speed position sensor. It may take up to 2 minutes for all vehicle systems to power down.

2. Test for less than 10 ohms between the low reference circuit terminal 6 and ground.

If 10 ohms or greater
Repair the open/high resistance in the circuit between the X201 inline connector and the steering wheel speed position sensor.

If less than 10 ohms

3. Ignition ON.

4. Verify a test lamp illuminates between the ignition circuit terminal 5 and ground.

If the test lamp does not illuminate
Repair the open/high resistance in the circuit between the X201 inline connector and the steering wheel speed position sensor.

If the test lamp illuminates

5. Ignition OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down.

6. Test for less than 70 ohms between the serial data circuits terminal 2 and 3.

If 70 ohms or greater
Repair the open/high resistance in the circuits between the X201 inline connector and the steering wheel speed position sensor.

If less than 70 ohms

7. Replace the steering wheel speed position sensor.
