Power Locks
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.
The power lock/unlock feature commands all of the vehicle doors, including the liftgate, to lock or unlock upon a command from the door lock control switch or remote transmitter. Power locking and unlocking of the doors functions independently of the key position, vehicle speed or transaxle position. The smart junction box (SJB) activates the power door lock relays to supply the correct power and grounds for the door lock actuators.
