System Description
NLEL0649
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.

1. Print all the data of “SELF-DIAG RESULTS” and “DATA MONITOR” for “ENGINE”, “ABS” and “SMART
ENTRANCE” displayed on CONSULT-II. Refer to the following.
‰
“DTC U1000, U1001 CAN COMMUNICATION LINE” (EC-1011 or EC-1318) for “ENGINE”
‰
“Inspection 13 CAN Communication System” (BR-140) for “ABS”
‰
“CAN Communication Line Check” (EL-351) for “SMART ENTRANCE”
2. Attach the printed sheet of “SELF-DIAG RESULTS” and “DATA MONITOR” onto the check sheet. Refer
to “CHECK SHEET” (EL-518).
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-518).
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
(EXAMPLE)” (EL-519).
