1035 - CAN COMMUNICATIONS NO MESSAGE FROM STEERING ANGLE SENSOR





When Monitored and Set Condition

- When Monitored: With the ignition on. The Controller Antilock Brake (CAB) monitors the status of the Steering Angle Sensor.
- Set Condition: The DTC will set if a malfunction is detected between the CAB and the Steering Angle Sensor.





For a complete Antilock Brake System (ABS) Circuit Diagram Brakes - ABS Electrical Diagnostics.

NOTE: This DTC will possibly set if the battery has been disconnected. Before performing any diagnostics confirm that the steering angle sensor is calibrated correctly. If the DTC is current, and the battery has been previously disconnected, perform the following procedure to recalibrate the steering angle sensor.
- Turn the ignition switch on.
- Rotate the steering wheel to the center position.
- Rotate the steering wheel to the full left stop.
- Rotate the steering wheel to the full right stop.
- Rotate the steering wheel back to the center position.
- Sensor recalibration is now complete, and the ESP/BAS light should be off. If the light is still on, continue to Step 1 of the Diagnostic Test for this DTC.


Diagnostic Test

1. CHECK STEERING ANGLE SENSOR SIGNAL VOLTAGE




NOTE: Inspect Fuse 14 located in the Underhood Accessory Fuse Block. If the fuse is open, repair the cause of the open fuse before continuing.

Turn the ignition off.
Disconnect the ESP Yaw Rate/Lateral Acceleration Sensor harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Turn the ignition on.
Measure the voltage of the Steering Angle Sensor Signal circuit at the ESP Yaw Rate/Lateral Acceleration Sensor harness connector while slowly rotating the steering wheel from the full right position to the full left position.

NOTE: It may be helpful to raise the front wheels off the ground and support the vehicle using appropriate safety measures.

Does the voltage vary between 7.0 and 9.5 volts?

Yes

- Replace the Controller Antilock Brake (CAB) Module. Removal.
- Perform ABS VERIFICATION TEST. ABS Verification Test

No

- Go to 2

2. MEASURE STEERING ANGLE SENSOR FUSED B(+) CIRCUIT VOLTAGE




Turn the ignition off.
Disconnect the Steering Angle Sensor harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Turn the ignition on.
Measure the voltage of the Fused B(+) circuit at the Steering Angle Sensor harness connector.
Is the voltage above 10 volts?

Yes

- Go to 3

No

- Repair the Steering Angle Sensor Fused B(+) circuit.
- Perform ABS VERIFICATION TEST. ABS Verification Test

3. MEASURE STEERING ANGLE SENSOR FUSED IGNITION SWITCH OUTPUT CIRCUIT VOLTAGE




With the ignition on.
Measure the voltage of the Fused Ignition Switch Output circuit at the Steering Angle Sensor harness connector.
Is the voltage above 10 volts?

Yes

- Go to 4

No

- Repair the Fused Ignition Switch Output circuit for an open.
- Perform ABS VERIFICATION TEST. ABS Verification Test

4. MEASURE THE STEERING ANGLE SENSOR SIGNAL CIRCUIT RESISTANCE




Turn the ignition off.
Disconnect the Yaw Rate/Acceleration sensor harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Measure the resistance of the Steering Angle Sensor Signal circuit from the Yaw Rate/Acceleration sensor harness connector to the Steering Angle Sensor harness connector.
Is the resistance below 5.0 ohms?

Yes

- Go to 5

No

- Repair the Steering Angle Sensor Signal circuit for an open.
- Perform ABS VERIFICATION TEST. ABS Verification Test

5. MEASURE THE STEERING ANGLE SENSOR SIGNAL CIRCUIT RESISTANCE




With the ignition off.
Measure the resistance between ground and the Steering Angle Sensor Signal circuit.
Is the resistance below 100k ohms?

Yes

- Repair the Steering Angle Sensor Signal circuit for a short to ground.
- Perform ABS VERIFICATION TEST. ABS Verification Test

No

- Go to 6

6. MEASURE THE VOLTAGE OF THE STEERING ANGLE SENSOR SIGNAL CIRCUIT




Turn the ignition on.
Measure the voltage of the Steering Angle Sensor Signal circuit at the Steering Angle Sensor harness connector.
Is the voltage below 1.0 volt?

Yes

- Go to 7

No

- Repair the Steering Angle Sensor Signal circuit for a short to voltage.
- Perform ABS VERIFICATION TEST. ABS Verification Test

7. MEASURE THE STEERING ANGLE SENSOR GROUND CIRCUIT RESISTANCE




Turn the ignition off.
Measure the resistance between ground and the Sensor Ground circuit.
Is the resistance below 5.0 ohms?

Yes

- Replace the Steering Angle Sensor. Removal.
- Perform ABS VERIFICATION TEST. ABS Verification Test

No

- Repair the Sensor Ground circuit for an open.
- Perform ABS VERIFICATION TEST. ABS Verification Test
