System Description

POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION
1. The power door lock system locks/unlocks all the doors.
  The main body ECU (multiplex network body ECU) receives lock/unlock request signals from a door control switch or the driver door key cylinder. Then, the main body ECU (multiplex network body ECU) sends these request signals to the door lock motors in each door to lock/unlock each door in response to the inputs.
