WARNING: This page is about a different car, the 2007 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The numbers below refer to the step numbers on the diagnostic table.
- 3: Perform the Steering Position Sensor Test in order to verify if the steering wheel position sensor (SWPS) is operating properly.
- 4: Verify that the Lateral Accelerometer Signal parameter is within the valid range.
- 5: Verify that the Yaw Rate Signal parameter is within the valid range.
