Gauges System Description (2024 2025)
Self-Diagnostic Function
The gauge control module is equipped with a function to the self-diagnostic function - Refer to: Gauges Self-Diagnostic Function (2024 2025) for 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 the fuel gauge becomes lower than the minimum tank fill threshold.
Multi-Information Display (MID)
The multi-information display (MID) provides the ODO/trip meter, outside air temperature, average fuel efficiency, available cruising range, instant fuel economy, oil life, seat belt reminder, tire pressure, intelligent traction management information 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 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).
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 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 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 TCM and the PCM via F-CAN. It calculates average fuel economy records, average/instant fuel economy, elapsed time, average speed, and range.
Select Position
The TCM sends the transmission shift position to the gauge control module, using the F-CAN. The multi-information display (MID) 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 washer fluid level switch* 1, idle stop OFF switch, intelligent traction management switch, ACC combination switch, parking brake switch, ECON switch, VSA OFF switch, CMBS OFF switch, and brake fluid level switch are connected directly to the gauge control module. The MICU creates turn signal inputs that connect directly to the turn signal indicators in the gauge control module. The steering commander switch assembly signal is transmitted to the gauge control module via the LIN.
*1: With washer fluid level Switch
Keyless Access System Information
The gauge control module receives information from the keyless access/TPMS control unit via the B-CAN to display the status of the keyless access system.
Buzzer
The gauge control module includes a buzzer to provide the driver with audible warnings.
Illumination Control
With the exterior lights turned off, the system is in the lights OFF state. Brightness can be adjusted using the dashlight's brightness controller.
Seat Belt Reminder
When the gauge control module receives the seat belt buckle switch signal from the SRS unit and each door switch signal from the MICU, the seat belt reminder sounds the alarm, turns on/blinks the seat belt warning light and displays the seat belt icon. If any seat belt transitions from buckled state to unbuckled state, the seat belt reminder turns on the seat belt warning light and displays the seat belt icon while the vehicle stops, or sounds the alarm, blinks the seat belt warning light and displays the seat belt icon while the vehicle runs.
Intelligent Traction Management
The intelligent traction management allows a vehicle to drive depending on the terrain by selecting one of the 4 modes(NORMAL, SNOW, MUD, and SAND). If a driver presses the intelligent traction management switch, the system adjusts the rear differential, VSA system, DBW, and A/T system accordingly.
