METER / GAUGE SYSTEM Hybrid System Indicator Malfunction

DESCRIPTION

A hybrid system indicator is adopted for this vehicle. In this circuit, the combination meter sub-assembly receives the hybrid system indicator level signal from the hybrid vehicle control ECU assembly via the CAN communication line. The combination meter sub-assembly controls the operation of the hybrid system indicator according to the hybrid system indicator level signal received from the hybrid vehicle control ECU assembly via the CAN communication line.
