Test Description

WARNING: This page is about a different car, the 2007 Saturn Vue. 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.

  1. 5:  By disconnecting the TR switch, the ground path for all TR switch circuits are removed and the PCM should recognize all circuits as open. The scan tool should display HI for all range signals.
  2. 6:  This step tests the TR switch wiring for an open or lack of signal voltage from the PCM.
  3. 7:  This step tests the TR switch wiring and the PCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal park should change to LOW.
  4. 8:  This step tests the TR switch wiring and the PCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal reverse should change to LOW.
  5. 9:  This step tests the TR switch wiring and the PCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal neutral should change to LOW.
  6. 10:  This step tests the TR switch wiring and the PCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal drive should change to LOW.
  7. 11:  This step tests the TR switch wiring and the PCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal intermediate should change to LOW.
  8. 12:  This step tests the TR switch wiring and the PCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal forward should change to LOW.
  9. 13:  This step tests the TR switch wiring and the PCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal low should change to LOW.
