Honda Pilot: Gauges System Description - Control/Function

The gauge control module provides the self-diagnostic function for checking the circuit of itself.

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 turn 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 ODO/trip meter, outside air temperature, average fuel efficiency, available cruising range, instant fuel economy, elapsed time, oil life, energy flow, 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 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 ATTENTION or CAUTION warning in the multi-information display (MID).

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 5 ºF ( 3 ºC) 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. It calculates average fuel economy records, average/instant fuel economy, range, elapsed time, average speed to display the results.

Ambient Meter

The ambient meter color changes to indicate real-time drive information and encourage the driver to drive fuel-efficiently. A green color indicates more fuel-efficient driving, and a blue color indicates less fuel-efficient driving.

Select Position

The PCM *1 or the TCM *2 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 these data.

*1: 6-speed A/T
*2: 9-speed A/T

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, idle stop OFF switch* 3 , intelligent traction management switch* 1 , snow switch* 2 , cruise control combination switch, parking brake switch, ECON switch, VSA OFF switch, CMBS OFF 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.

*1: AWD
*2: 2WD
*3: With auto idle stop system

Keyless Access System Information

The gauge control module receives information from the keyless access/TPMS control unit 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

With the exterior lights turned off, the system is in the lights OFF state. Brightness can be adjusted using the dashlights brightness controller.

Intelligent Traction Management

The intelligent traction management allows a vehicle to drive depending on the terrain by selecting one of the 4 modes (NOMAL, SNOW, MUD, and SAND)* 1 or 2 modes (NORMAL and SNOW)* 2 . If a driver presses the intelligent traction management switch* 1 or snow switch* 2 , the system adjusts the rear differential* 1 , VSA system, DBW, and A/T system.

*1: AWD
*2: 2WD

Gauges System Description - Overview

The gauge control module indicates the speedometer, the tachometer, the fuel gauge, the shift position indicator, and the several indicators. Also, the gauge control module has multi-information display (MID) which informs the driver of various vehicle conditions.
