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 and Tachometer
The TCM 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. The PCM provides an engine speed signal to the gauge control module using the F-CAN. Based on this input, the gauge control module displays the current engine speed in the tachometer.
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.
Multi-Information Display (MID) (With Multi-Information Display)
The multi-information display (MID) provides the ODO/trip meter, outside air temperature, average fuel economy, available cruising range, instant fuel economy, elapsed time, oil life, seat belt reminder, average speed, and the status of keyless access system. In addition, the diagnostic system displays the communication errors and the DTCs.
Information Display (Without Multi-Information Display)
The information display provides the ODO/trip meter, outside air temperature, average fuel efficiency, available cruising range, instant fuel economy, 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 TCM 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 information display or multi-information display (MID).
Ambient Meter
The ambient meter shows real-time driving information by color on the both sides of the tachometer 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.
Engine Coolant Temperature Gauge
The PCM provides an engine coolant temperature signal to the gauge control module using the F-CAN. When the engine coolant temperature is high, the gauge control module displays the warning in the multi-information display (MID).
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.
*: With multi-information display
Select Position
The TCM 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, cruise control combination switch, washer fluid level switch, automatic brake hold switch, ACC combination switch, VSA OFF switch, safety support switch, SPORT mode switch, and brake fluid level switch is connected 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 dashlights brightness control switch. When the exterior lights are off, the system is off.
