• 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.

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

• Tachometer

• Engine coolant temperature gauge

• Fuel gauge

• Warning lamps

• Indicator lamps

• 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.
