Trouble DiagnosesNJEL0540WORK FLOWNJEL0540S011. Print all the data of “SELF-DIAG RESULTS” and “DATA MONITOR” for “ENGINE”, “A/T” 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”
“DTC U1000 CAN COMMUNICATION LINE” (WITH EURO-OBD) (AT-192) for “A/T”
“CAN COMMUNICATION LINE” (All) (AT-395) for “A/T”
“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-516).
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-516).
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
