  1. Ignition OFF, disconnect the harness connector at the liftgate latch assembly.
  2. Ignition ON, verify the scan tool LGM Latch Ratchet Sw. parameter is Inactive.
    • If not the specified value, test the signal circuit terminal 6 for a short to ground. If the circuit tests normal, replace the LGM.
  3. Install a 3A fused jumper wire between the signal circuit terminal 6 and ground. Verify the scan tool LGM Latch Ratchet Sw. 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 LGM.
