Mazda CX-5 Service & Repair Manual / Body / Driver Info & Control / General / Instrument Cluster

Outline

The instrument cluster centrally controls the speedometer, tachometer, odometer/tachometer, fuel gauge, warning/indicator lights, trip computer, warning sounds and panel lights.

Function

The instrument cluster displays the following information to notify the user of the vehicle conditions.

Vehicle speed (speedometer)
Engine speed (tachometer)
Remaining fuel quantity (fuel gauge)
Traveled distance (odometer/tripmeter)
Indicator/warning lights
Average fuel economy, average vehicle speed, instantaneous fuel economy, remaining distance to empty (trip computer)

Speedometer display function

The instrument cluster controls the needle based on the vehicle speed signal sent via CAN transmission from the PCM, and displays the current vehicle speed. For details on the speedometer, refer to SPEEDOMETER.

Tachometer display function

The instrument cluster controls the needle based on the engine speed signal sent via CAN transmission from the PCM, and displays the current engine speed. For details on the tachometer, refer to TACHOMETER.

Fuel gauge display function

The instrument cluster displays the remaining fuel quantity based on the fuel gauge sender unit voltage signal sent via CAN transmission from the rear body control module (RBCM), and the fuel injection amount signal sent via CAN transmission from the PCM. For details on the fuel gauge, refer to FUEL GAUGE.

Odometer/tripmeter display function

The instrument cluster displays the total traveled distance/traveled distance over a specific interval based on the travel distance signal sent via CAN transmission from the PCM. For details on the odometer/speedometer, refer to ODOMETER/TRIPMETER.

Trip computer calculation function

The instrument cluster calculates the average fuel economy, average vehicle speed, instantaneous fuel economy, and the remaining distance to empty, and displays it on the LCD in the instrument cluster. For details on the trip computer, refer to TRIP COMPUTER INFORMATION SYSTEM.

Warning/Indicator lights illuminate/flash function

The instrument cluster illuminates/flashes the indicator/warning lights to notify the user of the vehicle system conditions.
The types of indicator/warning lights are as follows: Refer to Reference for details on each indicator/warning light.

Alarm operation function

The instrument cluster sounds the alarm using the alarm built into the instrument cluster to notify the user of the vehicle conditions.
The alarm types are as follows: Refer to Reference for details on each alarm.


Name	Reference
Lights-on reminder warning alarm	(See LIGHTS-ON REMINDER WARNING ALARM.)
Seat belt warning alarm	(See SEAT BELT WARNING ALARM.)
Air bag system warning alarm	(See AIR BAG SYSTEM WARNING ALARM.)
Keyless warning alarm	(See KEYLESS WARNING ALARM.)

Vehicle specification information transmission function

The instrument cluster sends vehicle specification information stored during configuration to the following modules via CAN transmission. The following modules perform configuration automatically by reading the vehicle specification information from the instrument cluster.

DSC HU/CU
EPS control module
AFS control module (with AFS)

Ambient temperature display switching function

The ambient temperature display can be switched between Celsius and Fahrenheit display. Refer to the workshop manual for the ambient temperature display switching procedure.
