OPERATED PROCEDURE
Power Door Lock Operation
BCM receives a LOCK signal from key fob. BCM locks all doors with input of LOCK signal from key fob.
When an UNLOCK signal is sent from key fob once, driver's door will be unlocked.
Then, if an UNLOCK signal is sent from key fob again within 5 seconds, all other door will be unlocked.
Power door lock operation mode can be changed using “DOOR LOCK-UNLOCK SET” mode in “WORK SUP-
PORT” of “POWER DOOR LOCK SYSTEM”.
Refer to BL-60, "
CONSULT-III Function (BCM)".
Power door lock operation mode can be changed also on the display.
Hazard and Horn Reminder
When the doors are locked or unlocked by key fob, power is supplied to hazard warning lamp and lamp flash
as follows
