System Description

NLEL0639

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
electonic 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 wir-
ing. Each control unit transmits/receives data but selectively reads required data only.

2. Attach the printed sheet of “SELF-DIAG RESULTS” and “DATA MONITOR” onto the check sheet. Refer

to “CHECK SHEET” (EL-471).

3. Based on the data monitor results, put “v” marks onto the items with “UNKWN” or “NG” in the check sheet

table. Refer to “CHECK SHEET“ (EL-471).

NOTE:
If “NG” is displayed on “CAN COMM” for the diagnosed control unit, replace the control unit.
4. According to the check sheet results (example), start inspection. Refer to “CHECK SHEET RESULTS
