SYSTEM DESCRIPTION

1. POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION
a. The power door lock system locks/unlocks all the doors at once.
The master switch and the door control switch on the passenger door send "lock/unlock" request signals to the body ECU. Then, the body ECU sends these requests to the lock motors in each door to lock/unlock all the doors at once in response to the inputs. (The BEAN is used when the master switch sends request signals to the body ECU.)

"2" step unlock function- is optional for unlocking procedures of the key linked lock for the driver side door.
