  1. POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION


    1. The power door lock system locks/unlocks all the doors.

      The master switch sends "lock/unlock" request signals to the main body ECU. Then, the main body ECU 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 door lock using a mechanical key sends request signals to lock or unlock the doors to the main body ECU.
