Unit

Description

Combination meter

Controls the following with the signals received from each unit via CAN communication and the sig-
nals from switches and sensors. 

• Speedometer

• Power meter

• High voltage battery status meter

• Fuel gauge

• Odo/trip meter

• Warning lamps

• Indicator lamps

• Warning chime

• Information display

IPDM E/R

IPDM E/R reads the ON/OFF signals of the oil pressure switch and transmits the oil pressure switch 
signal to the combination meter via BCM with CAN communication line.

Fuel level sensor unit

MWI-43, "Description"

.

Oil pressure switch

Refer to 

MWI-45, "Description"

.

ECM

Transmits the fuel consumption monitor signals to the combination meter with CAN communication 
line.

Brake ECU

Transmits the vehicle speed signal to the hybrid vehicle control ECU with CAN communication line.

BCM

• Transmits signals provided by various units to the combination meter with CAN communication 

line.

• Transmits the security signal to the combination meter.

Hybrid vehicle control ECU

• Transmits the vehicle speed signal to the combination meter with CAN communication line.
• Transmits shift position signal to the combination meter with CAN communication line.

Washer level switch

Transmits the washer level signal to the combination meter.

Brake fluid level switch
