METER / GAUGE / DISPLAY  METER / GAUGE SYSTEM(for Optitron Meter Type)  Hybrid System Indicator Malfunction  


DESCRIPTION

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