Normal Operation

WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

Remote locking and unlocking of the doors is accomplished by the smart junction box (SJB) receiving a command message from the RKE transmitter located on the integrated key. On vehicles not equipped with a memory feature, the SJB sends a signal directly to all of the door latches. On vehicles equipped with the memory feature, the SJB sends a controller area network (CAN) message to the driver door module (DDM). The DDM sends a signal directly to the LH front door latch. The SJB sends a signal to the RH front, LH rear and RH rear door latches.

All RKE transmitters must be present to begin diagnosis of the RKE system.

Aftermarket or dealer-installed systems may adversely affect the RKE operation. These systems should be disconnected before diagnosing the RKE concerns.
