SPEEDOMETER : System Description

INFOID:0000000003792512

• 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.
