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 “AUT O LOCK SET” mode in “WORK SUPPORT”.
Refer to BL-69, " 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 intermit-
tently 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 “P ANIC ALARM SET” mode in “WORK SUPPORT”.
Refer to BL-69, " 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 key-
fob. For detailed description, refer to LT-91 .
