Mazda CX-5 Service & Repair Manual: 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.

• If several alarm request signals are received simultaneously, the alarms sound according to the order of precedence in the following table.

Panel light control function

• The instrument cluster changes the panel light brightness according to the ignition switch being turned ON (engine off or on) or the TNS being illuminated. For details on the panel light, refer to PANEL LIGHT.

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.

• If the CAN signal cannot be received normally, the instrument cluster displays the 0 mark.

Fuel gauge

• If the CAN signal cannot be received normally, the instrument cluster displays the E mark.

Odometer/tripmeter

• Function not equipped.

Warning lights

• If the CAN signal cannot be received normally, the instrument cluster turns the warning light on.

Indicator lights

• If the CAN signal cannot be received normally, the instrument cluster turns the indicator light off.

Alarm

• If the CAN signal cannot be received normally, the instrument cluster stops the alarm.

Panel light

• If the CAN signal cannot be received normally, the instrument cluster turns the panel light on.

Trip computer information system

• If the CAN signal cannot be received normally, the instrument cluster displays the “— —“.

Ambient temperature display

• If the CAN signal cannot be received normally, the instrument cluster displays the “— —“ and does not display the ice mark.
