System Description

POWER DOOR LOCK SYSTEM DESCRIPTION

The power door lock system locks/unlocks all doors with a one-touch operation.
- The door control switch of the master switch assembly on the driver's door and the driver's door key cylinder send lock/unlock request signals to the theft warning ECU through the driver door ECU using the BEAN.
- The door control switch on the passenger door sends lock/unlock request signals to the theft warning ECU through the passenger door ECU using the BEAN.
- Upon receiving request signals, the theft warning ECU sends these signals to the door ECUs on each door using the BEAN. The door ECUs then lock/unlock each door.
