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 keyfob.

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 horn reminder can be turned ON/OFF with any LOCK mode.





Hazard and horn reminders do not operate if any door switch is ON (any door is OPEN).
How to change hazard and horn reminder modes
With CONSULT-III
Hazard reminder can be changed using "HAZARD LAMP SET" mode in "WORK SUPPORT".
Horn reminder can be changed using "HORN CHIRP SET" mode in "WORK SUPPORT". CONSULT-III Function (BCM) .
Without CONSULT-III
Refer to Owner's Manual for instructions.

Auto Door Lock Operation
Auto lock function signal is sent for operation when any of the following signals are not sent within 1 minute after the unlock signal is sent from the keyfob:
- when door switch is turned ON for open.
- when the key switch is turned ON.
- when the lock signal is sent from the keyfob.
Auto door lock mode can be changed using "AUTO LOCK SET" mode in "WORK SUPPORT". CONSULT-III Function (BCM) .

Panic Alarm Operation
When key switch is OFF (when ignition key is not inserted in key cylinder), BCM turns on and off horn intermittently with input of PANIC ALARM signal from keyfob.
BCM outputs to IPDM E/R for panic alarm signal (horn signal) as DATA LINE (CAN H line and CAN L line).
The alarm automatically turns off after 25 seconds or when BCM receives any signal from keyfob.
Panic alarm operation mode can be changed using "PANIC ALARM SET" mode in "WORK SUPPORT". CONSULT-III Function (BCM) .

Interior Lamp Operation
When the following conditions come:
- condition of interior lamp switch is in the DOOR position;
- door switch OFF (when all the doors are closed);
Remote keyless entry system turns on interior lamp (for 30 seconds) with input of UNLOCK signal from keyfob. For detailed description, Locations System Description .
