5A-18 Automatic Transmission/Transaxle:
Step 2. DTC / Freeze Frame Data Check, Record and
Clearance
First, referring to "DTC Check", check DTC (including
pending DTC). If DTC exists, print or write down DTC
and freeze frame data 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
/ Freeze Frame Data 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" 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.
