Gauges System Description
Self-Diagnostic Function
The gauge control module is equipped with a function to self-diagnose the internal circuits in the gauge control module.
Power/Charge Meter
The gauge control module receives information from motor 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.
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 is turn on in the event that indication of the fuel gauge becomes lower than the minimum tank fill threshold.
Multi-Information Display (MID)
The multi-information display (MID) provides the shift position indicator, speedometer, average fuel efficiency, instant fuel economy, ODO/trip meter, outside air temperature, ACC, LKAS, CMBS, elapsed time, seat belt reminder, average speed, eco guide, driver attention monitor, range and the status of keyless access system. In addition, the diagnostic system 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 the 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 upper of the power/charge meter 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 case of sport mode set, it turns on red.
Outside Air Temperature
The gauge control module uses measurements from the outside air temperature sensor or provided by the outside air 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/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/instant fuel economy, elapsed time, average speed, and range to display the results.
Select Position
The PCM provides transmission shift position to the gauge control module using the F-CAN. The shift position indicator indicates the shift position based on this data.
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, ACC combination switch, CMBS OFF switch, electric parking brake/automatic brake hold switch, VSA OFF switch, EV switch, sport mode switch, and brake fluid level switch are connect directly to the gauge control module. The audio remote-HFL switch signal is transmitted to the gauge control module via the LIN.
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 SEL/RESET knob. When the exterior lights are off, the system is off.
