METER / GAUGE SYSTEM Hybrid System Indicator Malfunction

DESCRIPTION

A hybrid system indicator (eco zone indicator) is adopted for this vehicle. In this circuit, the meter ECU receives the hybrid system indicator level signal from the power management control ECU via the CAN communication line. The meter ECU controls the operation of the hybrid system indicator according to the hybrid system indicator level signal received from the power management control ECU via the CAN communication line.
