Normal Operation
WARNING: This page is about a different car, the 2005 Mazda Tribute. 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 SJB receiving a command message from the remote transmitter. The SJB processes the command and provides voltage and ground to the door lock actuators. The remote transmitter has a minimum operating range of 10 m (33 feet).
All remote transmitters must be present to begin diagnosis of the remote keyless entry (RKE) system.
Aftermarket or dealer-installed system may adversely affect the RKE system operation. These systems should be disconnected before diagnosing any RKE concerns.
