Test Description

The numbers below refer to the step numbers on the diagnostic table.

  1. 3:  This test checks for a short to voltage in the steering wheel position sensor circuits.
  2. 5:  This test checks for a short to battery voltage on the 5-volt reference circuit
  3. 6:  This test checks for a short to voltage on the steering wheel position sensor signal circuit.
  4. 7:  This test checks for an open circuit in the reference low circuit.
  5. 8:  This test checks for a poor connection at the SSPS control module.
  6. 9:  This test checks for a poor connection at the steering wheel position sensor.
