2. Power door lock system function description (w/ passive entry & passive start)

a. Power door lock system can lock/unlock all doors by remote controller, mechanical key, central controls 

and contact switch on handle operation.
 Remote controller sends lock/unlock request signals to Passive Entry & Passive Start (PEPS) 

controller to control the Body Control Module (BCM) by CAN. Then, Body Control Module (BCM) 
sends these request signals to the lock fastener of each door in order to lock/unlock all doors 
simultaneously.

 After inserting the mechanical key into the driver side door key cylinder, all doors can be locked/

unlocked by turning the key clockwise or counterclockwise, but anti-theft function cannot be set.

 When the remote controller is outside vehicle, in an operation range of 1.5 m from front door handle, 

the door can be locked/unlocked by pressing door handle contact switch. 

 When the remote controller is outside back door, in a operation range of 1.5 m from back door 

handle, the door can be locked/unlocked by pressing back door handle contact switch. 

 Function active: effective at any time, even when engine starts.
 Lock success: when all doors are closed fully, lock signal from the center controls is input to execute 

the lock command.

 Lock failure: when at least one door is not closed fully, lock signal from the center controls is input to 

execute the lock command, and then lock command is executed after 1 second delay.

 Unlock success: unlock signal from the center controls is input to execute the lock command, 

regardless of whether the doors are closed fully.

 Door lock response: when the protection is not activated, Body Control Module (BCM) responses to 

each input of lock or unlock.
