Sleep/Wake-Up Control

Sleep Control:




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:




WAKE-UP CONTROL
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:
- All switches combined or connected with BCM
- All switches combined or connected with LCU
