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 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. 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 indication of the fuel gauge becomes lower than the minimum tank fill threshold.

Multi-Information Display (MID) 

The multi-information display (MID) provides the trip meter, average fuel economy, available cruising range, instant fuel economy, oil life, seat belt reminder, and the status of keyless access system. In addition, the diagnostic system displays the communication errors and the DTCs.

Odometer 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) and information area.

Ambient Meter 

The ambient meter shows real-time driving information by color on the upper sides of the tachometer which promotes 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 Air Temperature 

The gauge control module 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°F ( 3°C) to meet the customer's expectations.

Average Fuel Economy/Instant Fuel Economy, Range 

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 and range to display the results.

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, CMBS OFF switch, idle stop OFF switch, active damper system switch, idle stop off switch, snow switch, audio remote-HFL switch, safety support switch, and brake fluid level switch connected directly to the gauge control module.

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.
