OPERATION 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 an 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)
- 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.





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).

Trunk Lid Operation
When a TRUNK OPEN signal is sent with key OFF (ignition key removed from key cylinder) from keyfob, power is supplied
- through BCM terminal 53
- to trunk lid opener actuator terminal 1.
When power and ground are supplied, trunk lid opener actuator opens trunk lid.

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