POWER DOOR LOCK CONTROL 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 multiplex network body ECU. Then, the multiplex network body ECU transmits these requests to the lock motors in each door to lock/unlock all the doors simultaneously.
- Operating the driver side and passenger side door locks using a key sends lock/unlock request signals to the multiplex network body ECU. The driver side door key-linked lock function has an optional unlock method called the "2-step unlock function." Refer to the table below in step b for details on this function.

The power door lock control system has the following functions:
