PLUG-IN CHARGE CONTROL SYSTEM Charging Indicator Circuit

DESCRIPTION

The plugin charge control ECU assembly illuminates the charging indicator to inform the driver that the vehicle is being plug-in charged. The plugin charge control ECU assembly turns off the charging indicator when the plug-in charging completes successfully. The plugin charge control ECU assembly also blinks the charging indicator if a plug-in charging malfunction occurs.
