The numbers below refer to the step numbers on the diagnostic table.
This step tests the primary circuit of the access panel relay.
This step tests if the remote control door lock receiver is receiving and acting on an input from the transmitter.
An open remote function actuator (RFA) fuse may be caused by a short to ground in the access panel actuator voltage supply circuit or a shorted access panel actuator.
