Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the I/P multifunction switch.
  2. Test for less than 10 Ω between the ground circuit terminal 3 and ground.
    • If greater than the specified range, test the ground circuit for a open/high resistance.
  3. Ignition ON, verify the scan tool LGM 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 liftgate control module.
  4. Install a 3 A fused jumper wire between the signal circuit terminal 8 and ground. Verify the scan tool LGM 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 liftgate control module.
  5. Verify the scan tool LGM 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 liftgate control module.
  6. Install a 3 A fused jumper wire between the signal circuit terminal 7 and ground. Verify the scan tool LGM 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 liftgate control module.
  7. If all circuits test normal, test or replace the I/P multifunction switch.
