ENGINE GENERAL INFORMATION AND DIAGNOSIS (TBI FOR G10) 6-11
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
analysis and diagnosis.
2. DIAGNOSTIC TROUBLE CODE (DTC) / FREEZE FRAME DATA CHECK, RECORD AND
CLEARANCE
First, check DTC (including pending DTC), referring to “DTC check” section. If DTC is indicated, print it and
freeze frame data or write them down and then clear them by referring to “DTC clearance” section. DTC indi-
cates 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 5.
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.
NOTE:
If only Automatic transmission DTCs (P0705 / P0720 / P0753 / P0758 / P0751 / P0756) or Immobilizer
DTCs (P1620 – P1623) are indicated in this step, perform trouble diagnosis according to “Diagnosis”
in Section 7B or Section 8G.
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” 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. RECHECKING AND RECORD OF DTC / FREEZE FRAME DATA
Refer to “DTC check” section for checking procedure.
8. ENGINE BASIC INSPECTION AND ENGINE DIAGNOSIS TABLE
Perform basic engine check according to the “Engine Basic Inspection Flow Table” 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
DIAGNOSIS FLOW TABLE and based on symptoms appearing on the vehicle (symptoms obtained through
steps of customer complaint analysis, trouble symptom confirmation and / or basic engine check) and repair
or replace faulty parts, if any.
9. TROUBLESHOOTING FOR DTC (See each DTC Diag. Flow Table)
Based on the DTC indicated in Step 5 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 (PCM) 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.
