lowing.

11 Final Confirmation Test
1) Clear DTC if any.
2) Perform final confirmation test referring to
"Final Confirmation Test" in the following.
Is there any problem symptom, DTC or abnor-
mal condition?
1. CUSTOMER COMPLAINT ANALYSIS
Record details of the problem (failure, complaint) and how it occurred as described by the customer. For this
purpose, use of such an inspection form will facilitate collecting information to the point required for proper anal-
ysis and diagnosis.
2. DIAGNOSTIC TROUBLE CODE (DTC)/FREEZE FRAME DATA CHECK, RECORD AND CLEARANCE
First, check DTC (including pending DTC), referring to "DTC Check" in this section. If DTC is indicated, print it
and freeze frame data or write them down and then clear them by referring to "DTC Clearance" in this section.
DTC indicates malfunction that occurred in the system but does not indicate whether it exists now or it occurred
in the past and the normal condition has been restored now. To check which case applies, check the symptom in
question according to Step 5 and recheck DTC according to Step 6 and 7.
Attempt to diagnose a trouble based on DTC in this step only or failure to clear the DTC (including pending DTC)
in this step will lead to incorrect diagnosis, trouble diagnosis of a normal circuit or difficulty in troubleshooting.
NOTE:
If only automatic transmission DTC P0705 (No.72) to P0758 (No.63/64), or P1875 is indicated in this
step, proceed to DIAGNOSIS in Section 7B1.
3 AND 4. VISUAL INSPECTION
As a preliminary step, be sure to perform visual check of the items that support proper function of the engine
referring to "Visual Inspection" in this section.
5. TROUBLE SYMPTOM CONFIRMATION
Based on information obtained in Step 1 Customer complaint analysis and Step 2 DTC/freeze frame data check,
confirm trouble symptoms. Also, reconfirm DTC according to "DTC Confirmation Procedure" described in each
DTC Diagnosis section.
6 AND 7. DTC/FREEZE FRAME DATA RECHECK, RECORD AND CLEARANCE
