  1. Disconnect the liftgate control module connector C2.
  2. Using a DMM verify that 1-3 ohms of resistance is present between the liftgate latch motor control circuit terminals in the harness connector.
    • If excessive resistance is present between the motor control circuits, replace the liftgate latch assembly.
  3. Using a DMM verify that no continuity is present between either of the motor control circuit terminals in the harness connector and ground.
    • If continuity is present from a motor control circuit and ground, replace the liftgate latch assembly.
  4. If the liftgate latch motor control circuits test normal, replace the liftgate control module.
