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 power management control ECU 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 power management control ECU via the CAN communication line.

  3. READ VALUE USING GTS (HYBRID SYSTEM INDICATOR)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Combination Meter / Data Test.
