Gauges System Description - Control/Function
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. The low fuel indicator lights in the event that indication of the fuel gauge becomes lower than the minimum tank fill threshold. Information Display (Without Multi-Information Display (MID))
The information display provides the ODO/trip meter, outside air temperature, average/instant fuel economy, clock, oil life, and the status of keyless access system. In addition, the diagnostic system displays the communication errors and the DTCs. Multi-Information Display (MID) (With Multi-Information Display (MID))
The multi-information display (MID) provides the ODO/trip meter, average fuel efficiency, available cruising range, instant fuel economy, elapsed time, oil life, seat belt reminder, average speed, and the status of keyless access system and driving support. 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 ODO and trip meters. The mileage values are displayed in the information display. Engine Coolant Temperature Indicator
The PCM provides an engine coolant temperature signal to the gauge control module using the F-CAN. When the engine coolant temperature is higher than the specified value, the temperature indicator is on or blinks in red. When the engine coolant temperature is lower than the specified value, the temperature indicator is on in blue. Outside Air Temperature
The gauge control module uses measurements from outside air temperature sensor or provided by the outside air temperature sensor signal from climate control unit via the B-CAN. The outside air temperature indicator's displayed temperature can be recalibrated ![]() ![]() Average Fuel Economy and Instant Fuel Economy
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 to display the results. Select Position (CVT)
The PCM provides transmission selector position to the gauge control module using the F-CAN. Based on this data, the gauge control module illuminates the appropriate shift position indicator. Gauge Control Module Receives Information
The gauge control module receives information from each control unit via F-CAN and B-CAN communication to turn on or flash the indicators. The parking brake switch, washer fluid level switch, fuel gauge sending unit, VSA off switch, cruise control combination switch, ECON switch, CMBS OFF/LDW OFF switch, TPMS switch, brake fluid level switch, and select/reset/information switch connect directly to the gauge control module. The gauge control module receives the turn signal indicators signal from the MICU via B-CAN and activates the turn signal indicator. Keyless Access System Information
The gauge control module receives information from the keyless access control unit via 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
With the exterior lights turned off, the system is in the lights off state. Brightness can be adjusted using the dashlights brightness controller. |
