SYSTEM
Low power consumption mode (BCM sleep)- Low power consumption control is active
- CAN transmission is stopped
LOW POWER CONSUMPTION CONTROL WITH BCM
BCM reduces the power consumption with the following operation in the low power consumption mode.
 The reading interval of the each switches changes from 10 ms interval to 60 ms interval.
Sleep mode activation
 BCM receives the sleep-ready signal (ready) from IPDM E/R, combination meter and automatic back door
control module via CAN communication.
 BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful- filled.
 Each unit stops the transmission of CAN communication with the sleep wake up signal. BCM is in CAN com- munication sleep mode.
 BCM is in the low power consumption mode and perform the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
Sleep condition
Wake-up operation
 BCM transmits sleep wake up signal (wake up) to eac h unit when any condition listed below is established,
and then goes into normal mode from low power consumption mode.
 Each unit starts transmissions with CAN communication by receiving sleep wake up signals. Each unit trans- mit wake up signals to BCM with CAN communication to convey the start of CAN communication.

 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.
