6-2-12 ENGINE GENERAL INFORMATION AND DIAGNOSIS (M13 ENGINE)
Step
11 Final Confirmation Test
1) Clear DTC if any.
2) Perform final confirmation test referring to "Final
Confirmation Test" in followings.
Is there any problem symptom, DTC or abnormal condi-
tion?
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 4 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 in this step will lead to
incorrect diagnosis, trouble diagnosis of a normal circuit or difficulty in troubleshooting.
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 Flow Table".
6. and 7. RECHECKING AND RECORD OF DTC/FREEZE FRAME DATA
Refer to "DTC check" in this section for checking procedure.
8. ENGINE BASIC INSPECTION AND ENGINE SYMPTOM DIAGNOSIS
Perform basic engine check according to the "Engine Basic Inspection" first. When the end of the flow table has
been reached, check the parts of the system suspected as a possible cause referring to "Engine Symptom Diag-
nosis" and based on symptoms appearing on the vehicle (symptoms obtained through steps of customer com-
plaint analysis, trouble symptom confirmation and/or basic engine check) and repair or replace faulty parts, if
any.
9. DIAGNOSTIC TROUBLE CODE FLOW TABLE (See each DTC Diag. Flow Table)
Based on the DTC indicated in Step 6 or 7 and referring to the applicable DTC diag. flow table in this section,
locate the cause of the trouble, namely in a sensor, switch, wire harness, connector, actuator, ECM or other part
and repair or replace faulty parts.
10. CHECK FOR INTERMITTENT PROBLEM
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to
"Intermittent and Poor Connection" in Section 0A and related circuit of DTC recorded in Step 2.
11. FINAL CONFIRMATION TEST
Confirm that the problem symptom has gone and the engine is free from any abnormal conditions. If what has
been repaired is related to the DTC, clear the DTC once, perform DTC confirmation procedure and confirm that
no DTC is indicated.
Action Yes
Go to Step 6. End.
