INSTRUMENT CLUSTER

Outline

• The instrument cluster centrally controls the speedometer, tachometer, odometer/tachometer, fuel gauge, warning/indicator lights, TFT LCD (Type A only), 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)

• Average fuel economy, average vehicle speed, instantaneous fuel economy, remaining distance to empty (trip computer)

• Indicator/warning lights

• Indicator/warning messages (Type A only)

Speedometer display function

• The instrument cluster controls the speedometer 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. (See SPEEDOMETER.)

Tachometer display function

• The instrument cluster controls the tachometer 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. (See TACHOMETER.)

Fuel gauge display function

• The instrument cluster displays the remaining fuel quantity based on the fuel gauge resistance signal sent via CAN transmission from the RBCM, and the fuel injection amount signal sent via CAN transmission from the PCM. For details on the fuel gauge, refer to FUEL GAUGE. (See 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. (See 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. (See 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.

Type A (with TFT LCD)

^*1

For the system without the warning light/indicator light, refer to the message in the LIQUID CRYSTAL DISPLAY (LCD).

Type B (without TFT LCD)

Alarm operation function

• The instrument cluster sounds the alarm using the buzzer 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. (See 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/CM

• EPS control module

• AFS control module (with AFS)

• LASER SENSOR (with smart city brake support (SCBS))

Battery discharge suppression function

NOTE:

• This function is established for suppressing battery discharge during vehicle manufacture and shipment, however, if a room fuse is removed from a vehicle while the total traveled distance is low, the function may operate when the vehicle is in the market.

• The battery discharge suppression is a function in which the instrument cluster sends a battery discharge suppression signal to the following units based on the room fuse condition and the total traveled distance, and suppresses battery discharge by restricting the operation of electric load for the following units.

• The battery discharge suppression function operates when the total traveled distance is the threshold or less and the room fuse has been removed.

• When the battery discharge suppression function is operated, the instrument cluster displays F0-002, F0-HHH, F0-LLL in the odometer/tripmeter of the instrument cluster to indicate that the battery discharge suppression function is operating.

• The battery discharge suppression function is stopped under the following conditions.

• Room fuse is installed

• Engine is started

• Total traveled distance exceeds the threshold value

Fail-safe

Speedometer

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

Tachometer

• 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 turns off one segment at regular time intervals since the segments calculated based on the signal last received are displayed.

Odometer/tripmeter

• If the instrument cluster detects a malfunction in the internal CPU, the instrument cluster displays the “— —“.

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 instrument cluster detects a malfunction in the internal CPU, the instrument cluster displays the “— —“.

Ambient temperature display

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