OPERATED PROCEDURE
Power Door Lock Operation
BCM receives a LOCK signal from keyfob. BCM locks 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 horns 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)

Horns sound once with LOCK function when this feature is set ON.
The hazard reminder has modes 1, 2, 3 or 4. The horn reminder can be turned ON/OFF with any LOCK mode.
Operating function of hazard reminder
Hazard and horn reminders do not operate if any door switch is ON (any door is OPEN).
