- Entire Combination Meter does not Operate
DESCRIPTION
This circuit is the power source circuit for the meter. This circuit provides two types of power sources; one is a constant power source mainly used as a backup power source, and the other is an IG power source mainly used for signal transmission. The constant power source is mainly used as a backup power source for the meter ECU, however, it is also used for CAN communication. If a voltage of 12 V is not applied to terminal IG2 when the power switch is turned on (IG), the indicators will not operate.
