Gauges System Description - Control/Function
Self-Diagnostic Function
The gauge control module is equipped with a function to self-diagnose the inside circuits in the gauge control module.
Speedometer and Tachometer
The PCM
*1
or TCM
*2
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.
*1: M/T
*2: CVT
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) (With Multi-Information Display)
The multi-information display (MID) provides the ODO/trip meter, outside air temperature, average fuel economy, available cruising
range, instant fuel economy, elapsed time, 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.
Information Display (Without Multi-Information Display)
The information display provides the ODO/trip meter, outside air temperature, average fuel efficiency, available cruising range, instant
fuel economy, oil life, seat belt reminder, and the status of the keyless access system*. In addition, the diagnostic system displays the
communication errors and the DTCs.
*: With keyless access system
ODO Meter and Trip Meter
The PCM
*1
or TCM
*2
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 information display or multi-
information display (MID).
*1: M/T
*2: CVT
Ambient Meter (Except Si and Type-R)
The ambient meter shows real-time driving information by color on the both sides of the tachometer which promote 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 Temperature Gauge
The gauge control module uses measurements from the outside air temperature sensor or 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 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, elapsed time
*
, average speed
*
, and range
to display the results.
*: With multi-information display
