DESCRIPTION
This circuit is the power source circuit for the combination meter. This circuit provides 2 power source types: one is a constant power source mainly used as a backup power source, and the other is a power source mainly used for signal transmission. The constant power source is mainly used as a backup power source for the meter CPU. However, it is also used for communication. If a voltage of 12 V is not applied to terminal IG+ when the engine switch is on (IG), indicators will not operate.
