System Description

The power door lock system locks/unlocks all the doors simultaneously.
The master switch and the door control switch on the passenger side door send "lock/unlock" request signals to the door lock control relay. Then, the door lock control relay sends these requests to the lock motors in each door to lock/unlock all the doors simultaneously.

Operating the driver side and passenger side door lock using a key sends request signals to lock/unlock the doors to the door lock control relay. The driver side door key-linked lock function has an optional unlock method called the "2-step unlock function". Please refer to POWER DOOR LOCK CONTROL SYSTEM FUNCTIONS for details of this function.

The power door lock control system has the following functions:
