REMOTE KEYLESS ENTRY SYSTEM
OPERATING PROCEDURE
BCM can receive signals from electronic key when key switch is OFF position (key is not in ignition key cylin-
der). It then sends the signals to LCU01 as DATA LINE A-3.
POWER DOOR LOCK OPERATION
When BCM receives a LOCK signal from electronic key, BCM will then send a LOCK signal [when all door
switches are OFF (all doors are closed)]
●
from its terminals 67 (DATA LINE A-3)
●
to driver door control unit (LCU01) terminal 8.
When an UNLOCK signal is sent from electronic key once, driver’s door will be unlocked.
Then, if an UNLOCK signal is sent from electronic key again within 5 seconds, all other doors will be unlocked.

BL-19, "POWER DOOR LOCK SYSTEM"
