DESCRIPTION
A hybrid system indicator has been included on this vehicle. In this circuit, the combination meter assembly (meter circuit plate) receives the eco-zone indicator level signal from the hybrid vehicle control ECU via CAN communication. The combination meter assembly (meter circuit plate) controls the operation of the hybrid system indicator according to the eco-zone indicator level signal received from the hybrid vehicle control ECU via CAN communication.
