I/P Switch Inoperative

WARNING: This page is about a different car, the 2007 Saturn Outlook. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the I/P switch assembly.
  2. Ignition OFF, test for less than 1 ohm of resistance between the ground circuit terminal 3 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify the scan tool PLGM Disable Switch parameter is Inactive.
    • If not the specified value, test the signal circuit terminal 8 for a short to ground. If the circuit tests normal, replace the PLGM.
  4. Install a 3A fused jumper wire between the signal circuit terminal 8 and ground. Verify the scan tool PLGM Disable Switch parameter is Active.
    • If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the PLGM.
  5. Verify the scan tool Front Control Switch parameter is Inactive.
    • If not the specified value, test the signal circuit terminal 7 for a short to ground. If the circuit tests normal, replace the PLGM.
  6. Install a 3A fused jumper wire between the signal circuit terminal 7 and ground. Verify the scan tool Front Control Switch parameter is Active.
    • If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the PLGM.
  7. If all circuits test normal, test or replace the I/P switch.
