-

-
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 communicating 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:
-
Ignition key switch (Insert)*
-
Ignition switch "ACC" or "ON"
-
Lighting switch (1st)
-
Door switches (all doors)
-
Trunk room lamp switch
-
Hood switch
-
Driver/passenger side door key cylinder tamper switch
-
Driver/passenger side door key cylinder switch
-
Trunk lid key cylinder switch
-
Multi-remote controller
-
Door Unlock sensors (all doors)
* 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, no electrical loads on the questionable LCU will
operate.
