NOTE
The form is a standard sample. It should be modified according to conditions characteristic of each
market.
Step 2. DTC Check, Record and Clearance
First, referring to "DTC Check", check DTC. If DTC exists, print or write down DTC and then clear malfunction DTC(s)
by referring to "DTC Clearance". Malfunction DTC indicates malfunction in the system but it is not possible to know
from it whether the malfunction is occurring now or it occurred in the past and normal condition has been restored. In
order to know that, check symptom in question according to Step 5 and then recheck DTC according to Step 6.
Diagnosing a trouble based on the DTC in this step only or failure to clear the DTC in this step may result in a faulty
diagnosis, trouble diagnosis of a normal circuit or difficulty in troubleshooting which is otherwise unnecessary.
Step 3 and 4. Visual Inspection
As a preliminary step, be sure to perform visual check of the items that support proper function of the A/T and engine
referring to "Visual Inspection".
Step 5. Trouble Symptom Confirmation
Check trouble symptoms based on information obtained in Step 1 Customer Complaint Analysis and Step 2 DTC
Check, Record and Clearance.
Also, reconfirm DTC according to "DTC Confirmation Procedure" described in each DTC Flow.
Step 6 and 7. Rechecking and Record of DTC
Refer to "DTC Check" for checking procedure.
Step 8. A/T Basic Check and A/T Symptom Diagnosis
Perform basic check of A/T according to "A/T Basic Check" first. When the end of the flow has been reached, check
the parts of the system suspected as a possible cause referring to "A/T Symptom Diagnosis" and based on symptoms
appearing on the vehicle (symptoms obtained through steps of customer complaint analysis, trouble symptom
confirmation and/or A/T basic check) and repair or replace faulty parts, if any.
Step 9. Troubleshooting for DTC
Based on the DTC indicated in Step 6 / 7 and referring to "DTC Table", locate the cause of the trouble, namely in a
sensor, switch, wire harness, connector, actuator, TCM or other part and repair or replace faulty parts.
Step 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 Inspection in Section 00 in related manual" and related circuit of DTC recorded in Step 2.
Step 11. Final Confirmation Test
Confirm that the problem symptom has gone and the vehicle is free from any abnormal conditions. If what has been
repaired is related to the malfunction DTC, clear the DTC once and check to ensure that no malfunction DTC is
indicated.
