Circuit/System Description

The status of charging events (including delays) is communicated to the user through a vehicle plug-in charge status indicator and audio tones. The vehicle vehicle plug-in charge status indicator, located on the top middle of the instrument panel, contains a green LED (charge status indicator) and yellow LED (charge pilot indicator) controlled by the Hybrid Powertrain Control Module 2 and a second green LED (charge complete indicator) controlled by the BCM. The indicator will have a short flash green when the vehicle is charging under automatic control. The flash rate increases from one to four as the battery charges. It will have a long flash green if the charging is delayed and will begin later. It will be illumined solid green when charging is complete. A solid lit yellow indicator means the vehicle is not able to accept a charge.
