System DescriptionNJEL0543CAN (Controller Area Network) is a serial communication line for real timeapplication. 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 unitshares 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 requireddataonly.

Trouble DiagnosesNJEL0545WORK FLOWNJEL0545S011. Print all the data of “SELF-DIAG RESULTS” and “DATA MONITOR” for “ENGINE” and “SMART
ENTRANCE” displayed on CONSULT-II. Refer to the following.
“DTC U1000, U1001 CAN COMMUNICATION LINE” (WITH EURO-OBD) (EC-116) for “ENGINE”
“DTC U1000, U1001 CAN COMMUNICATION LINE” (WITHOUT EURO-OBD) (EC-492) for “ENGINE”
“CAN Communication Line Check” (EL-380) for “SMART ENTRANCE”.
2. Attach the printed sheet of “SELF-DIAG RESULTS” and “DATA MONITOR” ontothe check sheet. Refer
to “CHECK SHEET” (EL-534).
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-534).
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-535).GI
