 When the BCM detects that the Intelligent Key is within the outside key antenna detection area. BCM trans-
mits the request signal to the Intelligent Key and check it is near the door.
 Intelligent Key receives the request signal and transmits the key ID signal to the BCM via remote keyless
entry receiver.
 BCM receives the key ID signal and compares it with the registered key ID.
 BCM illuminates lamps that are set, when key ID verification is OK.
TIMER FUNCTION
BCM can operate welcome light function, using the timer function, for 9 days, after key switch is turned OFF.
The timer function resets when the engine is started
*.Operating period of timer function may differ depending
on battery size.
*: Timer function does not stop if another Intelligent Key that has a different key ID is detected within the inte-
rior antenna detection area, when starting the engine.
OPERATION CONDITION
If the following condition are satisfi ed, welcome light function is operated.
OUTSIDE KEY ANTENNA DETECTION AREA
The outside key antenna detection area of door lock/unlock function
is in the range of approximately 80 cm (31.50 in) surrounding the
driver, passenger door handles (1) and back door handle (2). How-
ever, this operating range depends on the ambient conditions.
WELCOME LIGHT FUNCTION SETTING
Welcome light function operation mode can be changed using CONSULT-III
With CONSULT-III
Refer to DLK-41, "
INTELLIGENT KEY : CONSULT-III F unction (BCM - INTELLIGENT KEY)".
Without CONSULT-III
The welcome light function ON/OFF can be s witched by performing the following operation.
1. Turn ignition switch: OFF →ON
2. Press and hold the driver side door request switch for 5 seconds or more within 20 seconds after turning the ignition switch ON.
3. The switching is complete when combination meter buzzer sounds.
