SLEEP CONTROL
“Sleep control” prevents unnecessary power consumption. After the following conditions are met, the BCM
suspends the communication between itself and all LCUs. The whole IVMS is set in the “sleep” mode.
●
Ignition switch “OFF”
●
All electrical loads (in the IVMS) “OFF”
●
Timer “OFF”

WAKE-UP CONTROL
As shown above, when the BCM detects a “wake-up” signal, it wakes up the whole system and starts commu-
nicating again. When the “sleep” mode of all LCUs is canceled, the BCM returns to the normal control mode.
When any one of the following switches are turned ON, the “sleep” mode is canceled:
●
All switches combined or connected with BCM.
●
All switches combined or connected with LCU.
Fail-Safe System
NKS001G8
Fail-safe system operates when the signal from LCU is judged to be malfunctioning by BCM. If LCU sends no
signal or an irregular signal to BCM a certain number of times in succession, the IVMS is set in a fail-safe con-
dition. In the fail-safe condition, the electrical loads controlled by the switch on the questionable LCU will be
operated at fail-safe mode.
CONSULT-II Function (IVMS)
NKS001G9
CONSULT-II executes the following functions by combining data reception and command transmission via the
communication line from BCM: IVMS communication inspection, work support, self-diagnosis, data monitor
and active test display.

COMM DIAGNOSIS
Diagnoses continuity in the communication line(s), and of the function of the IVMS-com-
munication interface between the body control module and the local control units,
accomplished by transmitting a signal from the body control module to the local control
units.
WAKE-UP DIAGNOSIS
Diagnose 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.
