The Steering Control Module (SCM) has detected a code error from the Steering Angle Sensor.





1. DTC IS ACTIVE

NOTE: If P0562-BATTERY VOLTAGE LOW or P0563-BATTERY VOLTAGE HIGH is set along with this DTC, diagnose the battery voltage DTC first.

1. Ignition on, engine not running.
2. Turn the steering wheel from stop to stop at least three times.
3. With the scan tool, select View DTCs in the Steering Control Module.

Is the DTC status Active at this time?

Yes

- Go To 2

No

- Go To 4

2. STEERING ANGLE SENSOR TONE WHEEL
1. Turn the ignition off.
2. Remove the steering wheel.
3. Inspect the clockspring for loose mounting screws or damage.
4. Remove the clockspring.
5. Inspect the Steering Angle Sensor and Tone Wheel for damage, loose or missing mounting screws, etc.
