    Meter/Gauge 

    ITEM DETAILS CHART

    Item Details
    Speedometer Based on a signal received from the wheel speed sensor, the skid control ECU calculates the vehicle speed and transmits data to the combination meter (CAN).
    Tachometer The combination meter receives an engine speed signal from the ECM, and the gauge needle operates (CAN).
    ODO/TRIP meter
    • The combination meter receives a vehicle speed pulse integration signal from the skid control ECU, and the ODO/TRIP meter display operates (CAN).
    • Using the light control rheostat switch, the ODO/TRIP meter display changes.
    Fuel receiver gauge The combination meter receives fuel amount information measured by the fuel sender gauge, and the gauge needle operates (Direct line).
    Engine coolant temperature receiver gauge The combination meter receives an engine coolant temperature signal from the ECM, and the gauge needle operates (CAN).
    Oil pressure receiver gauge The combination meter receives an engine speed signal from the ECM (CAN), and receives an oil pressure sender signal from the oil pressure sender (Direct line). Then the meter measures signals and the gauge needle operates.
    Voltage meter Monitors IG voltage and the gauge needle operates (Direct line).

      CRUISE INFORMATION DISPLAY CHART

      Display Outline
      CURRENT Receives vehicle speed pulse signals (via the direct line and CAN) and fuel consumption data, and measures the instant fuel consumption.
      AFTER REFUELING Receives vehicle speed pulse signals (via CAN) and fuel consumption data, and measures the average fuel consumption from the time the vehicle was refueled.
      CRUISING RANGE
      • Calculates the estimated distance to empty.
      • The distance is calculated using the fuel gauge value and long-term learned fuel consumption value.
      AFTER START (Average speed) Receives vehicle speed pulse signals (via the direct line and CAN) and fuel consumption data, and measures the average vehicle speed from the time the engine was started.
      AFTER START (Travel distance) Receives vehicle speed pulse signals (via the direct line and CAN) and fuel consumption data, and measures the distance driven from the time the engine was started.
      Tire Pressure Reset Proceeding*1 Receives a tire pressure condition signal via CAN communication, and displays through the multi-display.
      HINT:
      *1: for U.S.A.
