SPEEDOMETER : System Description

INFOID:0000000009651472

SYSTEM DIAGRAM

DESCRIPTION

• The ABS actuator and electric unit (control unit) converts the rectangular wave signal provided by the wheel

sensor to a vehicle speed signal and transmits it to the combination meter via CAN communication. 

• The combination meter indicates the vehicle speed to the speedometer according to the vehicle speed sig-

nal received via CAN communication. 

TACHOMETER

TACHOMETER : System Description

INFOID:0000000009651473

SYSTEM DIAGRAM

DESCRIPTION

• ECM converts the pulse signal provided by the crankshaft position sensor to an engine speed signal and

transmits it to the combination meter via CAN communication.

• The combination meter indicates the engine speed to the tachometer according to the engine speed signal

received via CAN communication. 

ENGINE COOLANT TEMPERATURE GAUGE

ENGINE COOLANT TEMPERATURE GAUGE : System Description

INFOID:0000000009651474

SYSTEM DIAGRAM

DESCRIPTION

• ECM reads the engine coolant temperature signal from the engine coolant temperature sensor and transmits

the signal to the combination meter via CAN communication.

METER SYSTEM

• The combination meter indicates the engine coolant temperature to the engine coolant temperature gauge

according to the engine coolant temperature signal received via CAN communication. 

FUEL GAUGE

FUEL GAUGE : System Description

INFOID:0000000009651475

SYSTEM DIAGRAM

DESCRIPTION

Control Outline

The combination meter reads the fuel level sensor signal from the fuel level sensor unit and indicates the fuel
level to the fuel gauge. 

Refuel Control

The combination meter accelerates the fuel gauge if the all conditions listed below are met, or the ignition
switch is ON from OFF.
• Ignition switch is ON position.
• The vehicle is not moving.
• The fuel level change by 15   (4 US gal, 3-1/4 Imp gal) or more.

OIL PRESSURE WARNING LAMP

OIL PRESSURE WARNING LAMP : System Description

INFOID:0000000009651476

SYSTEM DIAGRAM

DESCRIPTION

• IPDM E/R receives an oil pressure switch signal from the oil pressure switch and transmits the signal to

BCM via CAN communication.

• BCM transmits the oil pressure switch signal received from IPDM E/R to the combination meter via CAN

communication.

• The combination meter turns ON/OFF the oil pressure warning lamp, according to an oil pressure switch sig-

nal received from BCM via CAN communication.
