Panic Function

When the panic button on the RKE transmitter is pressed it pulsates the headlamp, hazard lamps and horn relays and actuates the courtesy lamp relay. By pressing the button again the horn and exterior lamps will stop but the courtesy lamps will remain on until the BCM times them out or the ignition is turned on. The panic feature is able to be set if the ignition is on but only if the panic button is pressed prior to the vehicle being started, it will continue for three minutes or until the vehicle has reached a speed of 15 MPH, if not canceled by the operator. Actuating the headlamp, horn, hazard lamps and courtesy lamp relays with the DRBIII(R) will verify that the circuits and the body control module are OK. If the panic feature is still inoperable with both transmitters, replacement of the passenger door module will be necessary. If the function is inoperable with just one transmitter, then it is obvious that the transmitter must be replaced.
