1174 - STEERING ANGLE SENSOR NOT INITIALIZED





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.

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.


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

No

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

2. 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 3

No

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

3. VISUALLY INSPECT COMPONENTS FOR DAMAGE AND CORRECT INSTALLATION
Visually inspect the Steering Angle Sensor for damage and correct installation.
Are there any visible Steering Angle Sensor concerns?

Yes

- Correct the sensor concerns as necessary.
- Perform ABS VERIFICATION TEST. ABS Verification Test

No

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