Gauges System Description - Control/Function (2014 2015 2016)

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 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.

Multi-Information Display (MID) 

The multi-information display (MID) provides the odometer/trip meter, outside air temperature, average fuel efficiency, available cruising range, instant fuel economy, elapsed time, TPMS, gear position, 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.

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.

Engine Coolant Temperature 

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 ATTENTION or CAUTION warning in the multi-information display (MID).

Outside Air Temperature 

The gauge control module uses measurements from outside air temperature sensor provided by the relay control module via the B-CAN communication line to display the outside air temperature in the multi-information display. The outside air temperature indicator's displayed temperature can be recalibrated ± 5 °F (± 3 °C) to meet the client'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 communication. It calculates instant/average fuel economy, range to display the results.

Gauge Control Module Receives Information 

The gauge control module receives information from each control unit via F-CAN and B-CAN communication to light or flash the indicators. The parking brake switch, washer fluid level switch, steering commander switch, VSA OFF switch, integrated dynamics system switch, and brake fluid level switch connect 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 communication.

Keyless Access System Information 

The gauge control module receives information from the keyless access/TPMS control unit via B-CAN communication 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.
