SYSTEM DESCRIPTION

1. POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION

(a) The power door lock system locks/unlocks all the doors.

The power window regulator master switch assembly (door control switch) and door control switch assembly 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 door lock motors in each door to lock/unlock all the doors at once in response to the inputs.

Operating the driver side door lock using a mechanical key sends request signals to lock or unlock the doors to the main body ECU (multiplex network body ECU).
