Sleep/Wake-up Control
SLEEP CONTROL
SEL465TA
“Sleep” control prevents unnecessary power consumption. After the following conditions are met, the BCM
suspends the communication between itself and all LCU’s. The whole IVMS is set in the “sleep” mode.
I
Ignition switch “OFF”
I
All electrical loads (in the IVMS) “OFF”
I
Timer “OFF”
WAKE-UP CONTROL
SEL466T
As shown above, when the BCM detects a “wake-up” signal, it wakes up the whole system and starts com-
municating again. The “sleep” mode of all LCUs is now canceled, and the BCM returns to the normal control
mode. When any one of the following switches are turned ON, the “sleep” mode is canceled:
I
Ignition key switch (Insert)*
I
Ignition switch “ACC” or “ON”
I
Lighting switch (1st)
I
Interior lamp switch
I
Rear personal lamp switch
I
Door switches (all doors)
I
Multi-remote controller
I
Trunk room lamp switch
I
Hood switch

I
All switches combined or connected with LCU
* Also, when key is pulled out of ignition (ignition key switch is turned from ON to OFF), the “sleep” mode is
canceled.
Fail-safe System
Fail-safe system operates when the signal from LCU is judged to be malfunctioning by BCM. If LCU sends no
signal or an abnormal signal to BCM a certain number of times in succession, the IVMS is set in a fail-safe
condition. In the fail-safe condition, the electrical loads controlled by the switch on the questionable LCU will
be operated at fail-safe side.

DIAGNOSTIC ITEMS DESCRIPTION
MODE
Description
IVMS COMM DIAGNOSIS
Diagnosis of continuity in the communication line(s), and of the function of the communi-
cation interface between the body control module and the local control units, accom-
plished by transmitting a signal from the body control module to the local control units.
WAKE-UP DIAGNOSIS
Diagnosis of the “wake-up” function of local control units by having a technician input the
switch data into the local control unit that is in the temporary “sleep” condition.
SELF-DIAGNOSTIC RESULTS
—
DATA MONITOR
Displays data relative to the body control module (BCM) input signals and various control
related data for each system.
ACTIVE TEST
Turns on/off actuators, relay and lamps according to the commands transmitted by the
CONSULT-II unit.
WORK SUPPORT for WIPER
Wiper intermittent speed control by vehicle speed can be canceled or resumed.
WORK SUPPORT for MULT-REMOTE
CONT SYS
ID code of multi-remote controller can be registered and erased.
NOTE: When CONSULT-II diagnosis is operating, some systems under IVMS control do not operate.
