Ignition Battery Saver System

The ignition battery saver system is a system in which the BCM automatically shuts off the power supply (push-button ignition switch ON -> OFF) to protect the battery.

The BCM activates the ignition battery saver system 10 minutes after the ignition battery saver timer function operating conditions are met. Also, the meter display signal is transmitted to the combination meter via CAN communication as operation notice and operation confirmation, and the information display is operated.
