AUTOMATIC DOOR LOCK/UNLOCK FUNCTION (LOCK OPERATION)

The interlock door lock function is the function that locks all doors linked with the vehicle speed.

Vehicle Speed Sensing Auto Door Lock

All doors are locked when the vehicle speed reaches 10 km/h (6 MPH) or more.

BCM outputs the lock signal to all door lock actuators when it detects all doors are closed and the Nissan Pathfinder vehicle speed received from the ABS actuator and electric unit (control unit) via CAN communication becomes 10 km/h (6 MPH) or more.

AUTOMATIC DOOR LOCK/UNLOCK FUNCTION (UNLOCK OPERATION)

The automatic door lock/unlock function is the function that unlocks all doors linked with the key position or shift position. It has 2 types as per the following items.

IGN OFF Interlock Door Unlock

All doors are unlocked when the ignition position is changed from ON to OFF.

BCM outputs the unlock signal to all door lock actuators when it detects that the ignition position is changed from ignition switch ON to OFF.

P Range Interlock Door Unlock

All doors are unlocked when shifting the selector lever from any position other than the P to P position.

BCM outputs the unlock signal to all door lock actuators when it detects the shift position signal received from TCM via CAN communication is shifted from any position other than the P to P position.

Setting Change of Automatic Door Unlock Function

The unlock operation setting of the automatic door unlock function can be changed by combination meter setting.

REAR DOOR ALERT WARNING

This function is to prevent loss of luggage in the rear seat when driving, by setting the function with the combination meter in advance.
