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”
‰
“CAN Communication System” (BR-73) 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-580).
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-580).
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-581).
