POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION
The power door lock control system locks/unlocks all the doors.
The master switch and the door control switch on the front passenger door send "lock/unlock" request signals to the main body ECU (instrument panel junction block). Then, the main body ECU (instrument panel junction block) sends these request signals to the lock motors in each door to lock/unlock all the doors at once in response to the inputs.
Operating the driver's door lock using a mechanical key sends request signals to lock/unlock the doors to the main body ECU (instrument panel junction block).
