Power Door Lock Control System -- System Description



POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION
The power door lock control system locks/unlocks all the doors.
The power window regulator master switch assembly (door control switch) sends lock/unlock request signals to the driver side junction block assembly. Then, the driver side junction block assembly 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 driver side junction block assembly.
