Display Results (Past)

OK: Normal

0: There is malfunction now.

1 – 39: Displays when it finds malfunction in the past even if it is normal or there is a malfunction at present. Also, displays when diag-

System Description

NKS001VT

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
