Operation

Lock operation using front door key cylinder

1.  When the key is inserted in the front door key cylinder and a lock operation is performed, the front door key cylinder switch switches to the lock side.

2.  When the rear body control module (RBCM) detects a front door key cylinder switch lock signal (1), it turns the transistor on (2), and turns the door lock relay (lock side) on.

3.  When the door lock relay (lock side) turns on (3), the front and rear door lock actuator motors perform a lock operation (4), and the front and rear doors lock.

Unlock operation using front door key cylinder

1.  When the key is inserted in the front door key cylinder and an unlock operation is performed, the front door key cylinder switch switches to the unlock side.

2.  When the rear body control module (RBCM) detects a front door key cylinder switch unlock signal (1), it turns the transistor on (2), and turns the door lock relay (unlock side) on.

3.  When the door lock relay (unlock side) turns on (3), the front and rear door lock actuator motors perform an unlock operation (4), and the front and rear doors unlock.

Lock operation using driver's door lock knob

1.  When the driver's door lock knob is locked, the door lock-link switch switches to the lock side.

2.  When the rear body control module (RBCM) detects a door lock-link switch lock signal (1), it turns on (2) the transistor, and turns on the door lock relay (lock side).

3.  When the door lock relay (lock side) turns on (3), the front and rear door lock actuator motors perform a lock operation (4), and the front and rear doors lock.

Unlock operation using the driver's door lock knob

1.  When the driver's door lock knob is unlocked, the door lock-link switch switches to the unlock side.

2.  When the rear body control module (RBCM) detects a door lock-link switch unlock signal (1), it turns on (2) the transistor, and turns on the door lock relay (unlock side).

3.  When the door lock relay (unlock side) turns on (3), the front and rear door lock actuator motors perform an unlock operation (4), and the front and rear doors unlock.

Lock operation using door lock switch (with door lock switch)

1.  When the door lock switch is operated to lock, the door lock switch switches to the lock side.

2.  When the rear body control module (RBCM) detects a door lock switch lock signal (1), it turns the transistor on (2), and turns the door lock relay (lock side) on.

3.  When the door lock relay (lock side) turns on (3), the front and rear door lock actuator motors perform a lock operation (4), and the front and rear doors lock.

Unlock operation using the door lock switch (with door lock switch)

1.  When the door lock switch is operated to unlock, the door lock switch switches to the unlock side.

2.  When the rear body control module (RBCM) detects a door lock switch unlock signal (1), it turns the transistor on (2), and turns the door lock relay (unlock side) on.

3.  When the door lock relay (unlock side) turns on (3), the front and rear door lock actuator motors perform an unlock operation (4), and the front and rear doors unlock.

Double locking function (With double locking)

•  When all the doors and liftgate are closed and locked two times consecutively, the unlock operation for all door lock knobs is disabled.

1.  When the key is inserted in the front door key cylinder and a lock operation is performed, the front door key cylinder switch switches to the lock side.

2.  When the rear body control module (RBCM) detects a front door key cylinder switch lock signal (1), it turns the transistor on (2), and turns the door lock relay on.

3.  When the door lock relay turns on (3), the front and rear door lock actuator motors perform a lock operation (4), and the front and rear doors lock.

4.  When a lock operation is re-performed within approx. 3 s after performing it once, the front door key cylinder switch switches to the lock side.

5.  When the rear body control module (RBCM) detects a front door key cylinder switch lock signal (5), it turns the transistor on (6), and turns the double locking relay on.

6.  When the double locking relay turns on (7), the front and rear door lock actuator motors perform a lock operation (8), and the connection of front and rear door knobs is disconnected. Therefore, the lock/unlock operation cannot be performed using the front and rear door lock knobs.

Collision detection unlock function operation (with collision detection unlock function)

1.  When an air bag deploys, the SAS control module sends an air bag deployment signal to the instrument cluster (without Mazda ERA-GLONASS) / Mazda ERA-GLONASS control module (with Mazda ERA-GLONASS) as a CAN signal.

2.  The instrument cluster (without Mazda ERA-GLONASS) / Mazda ERA-GLONASS control module (with Mazda ERA-GLONASS) sends the air bag deployment signal to the rear body control module (RBCM).

3.  The rear body control module (RBCM) receives the air bag deployment signal and after approx. 6 s, it operates the front and rear door lock actuator motors, and the front and rear doors unlock.

Auto Door Lock Operation (with auto door lock function)

•  The auto door lock system functions to automatically lock and unlock all the doors and the liftgate.

•  The auto lock function automatically locks all the doors and the liftgate based on the vehicle speed or the selector lever range operation.

•  The auto unlock function unlocks all the doors and the liftgate based on the selector lever range or the operation of the ignition switch.

Note

•  The auto door lock operation setting can be changed using the personalization function. (See SECURITY AND LOCKS PERSONALIZATION.)

Auto door lock operation based on vehicle speed

•  When the vehicle speed reaches approx. 20 km/h {12 mph}, the rear body control module (RBCM) turns on the door lock relay based on the vehicle speed signal from the PCM (CAN signal), and locks all the doors and the liftgate.

Auto door lock operation based on shift position

•  When the selector lever is shifted from the park (P) position to any other position, the rear body control module (RBCM) turns on the door lock relay based on the selector lever input signal from the TCM (CAN signal), and locks all the doors and the liftgate.

Auto Door Unlock Operation

Auto door unlock operation based on shift position

•  When the selector lever is shifted from any position other than the park (P) position to the park (P) position, the rear body control module (RBCM) turns on the driver-side door unlock relay and the door unlock relay based on the selector lever input signal from the TCM (CAN signal), and unlocks all the doors.

Auto door unlock operation based on ignition switch position

•  If the engine is being started or the ignition switch is turned from the ON condition to off, the rear body control module (RBCM) turns on the driver-side door unlock relay and the door unlock relay and unlocks all the doors.
