SYSTEM DESCRIPTION
1. POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION
(a) The power door lock system locks/unlocks all doors.
The door control switch sends "lock/unlock" request signals to the main body ECU (driver side junction block assembly). Then, the main body ECU (driver side junction block assembly) sends these request signals to the lock motors in each door to lock/unlock all doors at once in response to the inputs.
Operating the driver door lock using a mechanical key sends request signals to lock/unlock door to the main body ECU (driver side junction block assembly).
