OPERATED PROCEDURE
Power Door Lock Operation BCM receives a LOCK signal from keyfob. BCM lock s all doors with input of LOCK signal from keyfob.
BCM receives a UNLOCK signal from keyfob. BCM unlocks all doors with input of UNLOCK signal from key-
fob.
Hazard and Horn Reminder When the doors are locked or unlocked by keyfob, power is supplied to sound horn and flash hazard warning
lamps as follows
• LOCK operation: 3 or 4 mode (lamps flash twice)
• UNLOCK operation: 2 or 4 mode (lamps flash once)
• Horn sounds once with LOCK function when this feature is set ON.
The hazard reminder has modes 1, 2, 3 or 4. The hor n reminder can be turned ON/OFF with any LOCK mode.
