    • If the latch does not perform as specified, replace the rear compartment lid latch.

Rear Compartment Lid Release Switch

  1. Ignition OFF, disconnect the harness connector at the rear compartment lid release switch.
  2. Test for infinite resistance between the signal terminal C and the ground terminal A with the switch in the open position.
    • If less than the specified value, replace the rear compartment lid release switch.
  3. Test for less than 2 ohms of between the signal terminal C and the ground terminal A with the switch in the closed position.
