Sleep/Wake-Up Control Mode

The sleep/wake-up control mode allows the communication between BCM and LCUs to be turned on and off as necessary to prevent unnecessary power consumption. When BCM detects that the ignition, electrical loads and timer are off, it will shut off communication with all LCUs and activate sleep mode in about 30 seconds.

Communication with all LCUs will be re-established (system in normal control mode) if BCM detects a wake-up signal from the data line to LCUs, or if a key switch "off" signal (ignition turned from on to off) is detected. The BCM will also re-establish communication with all LCUs if it detects an "on" signal from one of the following switches, which are directly connected to BCM.

• Key Switch (Key Inserted)
• Ignition Switch (ACC Or ON)
• Headlight Switch (First Detent)
• Door Switches (All)
• Trunk Lid Unlock Switch
• Trunk Compartment Light Switch
• Engine Hood Switch
• Multi-Remote Controller
• Door Unlock Sensors (All)
