Power Door Lock Control System -- System Description



POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION

  1. The power door lock system locks/unlocks all the doors.
    The master switch and the door control switch on the passenger door send "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's door lock using a mechanical key sends request signals to lock/unlock the doors to the main body ECU via the master switch.
