Unit

Description

Combination meter

Based on received signals from each unit, switch, and sensor, controls the following items.

• Speedometer

• Tachometer

• Engine coolant temperature gauge

• Fuel gauge

• Warning lamp

• Indicator lamp

• Information display

Fuel level sensor unit

Detects the fuel level in fuel tank using the fuel level sensor unit, and transmits the fuel gauge sig-
nal to the combination meter.

Oil pressure sensor

Detects the oil pressure of engine oil, and transmits the oil pressure sensor signal to the combi-
nation meter.

Transmits the following signals to the combination meter via CAN communication.

• Engine speed signal

• Engine coolant temperature signal

• Fuel consumption monitor signal

• Malfunction indicator lamp signal

• Engine status signal

• ASCD status signal

ABS actuator and electric unit 
(control unit)

Transmits the following signals to the combination meter via CAN communication.

• Vehicle speed signal

• ABS warning display signal

• VDC warning display signal

BCM

Transmits signals received from each unit and switch to the combination meter via CAN commu-
nication.

TCM

Transmits the following signals to the combination meter via CAN communication.
