Gauges System Description
Self-Diagnostic Function
The gauge control module is equipped with a function to self-diagnose the internal circuits of the gauge control module.
Speedometer
The PCM provides a vehicle speed signal to the gauge control module using the F-CAN. Based on this input, the gauge control module displays the current vehicle speed in the speedometer.
Fuel Gauge and Fuel Indicator
The gauge control module displays the fuel gauge based on input value from the fuel gauge sending unit (fuel tank unit). The low fuel indicator turns on in the event that the fuel gauge becomes lower than the minimum tank fill threshold.
Power/Charge Meter
The gauge control module receives information from the motor control module and the battery condition monitor module via F-CAN, and displays charging and discharging state of high voltage battery.
STATE of CHARGE (SOC) Meter
The gauge control module displays the remaining high voltage battery charge level.
Multi-Information Display (MID)
The multi-information display (MID) provides the ODO/trip meter, outside air temperature, average fuel economy, available cruising range, instant fuel economy, elapsed time, average speed, integrated driver support information, oil life, seat belt reminder, and the status of the keyless access system. In addition, the diagnostic function displays the communication errors and the DTCs.
ODO Meter and Trip Meter
The PCM provides a vehicle speed signal to the gauge control module using F-CAN. Based on this input, the gauge control module tracks mileage for the odometer and trip meters. The mileage values are displayed in the multi-information display (MID).
Ambient Meter
The ambient meter shows real-time driving information by color on the both ends of the gauge control module which promote fuel efficient driving. When the color is close to green, it means low fuel consumption driving. When the color is close to white, it means high fuel consumption driving. In the sport mode, the ambient meter colors to red regardless of driving conditions.
Outside Temperature Gauge
The gauge control module uses measurements from the outside air temperature sensor or uses the temperature sensor signal from the climate control unit via the B-CAN. The outside air temperature indicator's displayed temperature can be recalibrated
5 deg.F (
3 deg.C) to meet the customer's expectations.
Average Fuel Economy Records, Average Fuel Economy/Instant Fuel Economy, Range, Elapsed Time Display, Average Speed Display
The gauge control module receives signals such as fuel consumption, driving distance, vehicle speed, and engine speed from the PCM via F-CAN. It calculates average fuel economy records, average/instant fuel economy, elapsed time, average speed, and range.
Select Position
The SBW shifter control module sends the transmission shift position/mode to the gauge control module, using F-CAN.
Gauge Control Module Receives Information
The gauge control module receives information from each control unit via the F-CAN and the B-CAN to light or flash the indicators. The VSA modulator-control unit (indicator signal), ECON switch, washer fluid level switch *, automatic brake hold switch, ACC combination switch, VSA OFF switch, safety support switch, SPORT mode switch, EV switch, fuel gauge sending unit, dashlights brightness control switch, TRIP switch and brake fluid level switch is connected directly to the gauge control module. The audio remote-HFL switch signal receives via the LIN.
*: KC models
Keyless Access System Information
The gauge control module receives information from the body control module via the B-CAN to display status of the keyless access system.
Buzzer
The gauge control module includes a buzzer to provide the driver with audible warnings.
Illumination Control
The illumination brightness can be adjusted using the dashlights brightness control switch. When the exterior lights are off, the system is off.
