  1. Ignition OFF, disconnect the X3 harness connector at the liftgate control module.
  2. Test for less than 15 Ω between the control terminal 14 at the liftgate control module and ground.
    • If greater than the specified range, replace the liftgate control module.
  3. Test for less than 15 Ω between the control terminal 13 at the liftgate control module and ground.
    • If greater than the specified range, replace the liftgate control module.
  4. Test for 9-10 Ω between the control circuit terminal 13 and control circuit terminal 14 at the liftgate motor assembly.
    • If less than the specified range, test either control circuit for a short to ground. If the circuits test normal, replace the liftgate actuator assembly.
    • If greater than the specified range, test either control circuit for a short to voltage or an open/high resistance. If the circuits test normal, replace the liftgate actuator assembly.
