1. POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION
(a) The power door lock control system locks/unlocks all the doors.
The power window regulator master switch assembly (door control switch assembly
LH) and the door control switch assembly RH on the front passenger door send "lock/unlock"
request signals to the main body ECU (multiplex network body ECU). Then, the main
body ECU (multiplex network 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 using a mechanical key sends request signals to lock/unlock
the doors to the main body ECU (multiplex network body ECU).
