Step 2. DTC / Freeze Frame Data Check, Record and
Clearance
First, referring to “DTC Check”, check DTC and 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 an
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 engine and
automatic transaxle 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 and
Freeze Frame Data
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
“applicable DTC flow”, 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.

cycle.
• 2 driving cycles: MIL or transmission warning light lights up when the same DTC is detected also in
the next driving cycle after DTC is detected and stored temporarily in the first driving cycle.
• Driving cycle with (*): MIL or transmission warning light does not light up but TCM detects and
stores DTC.

Also check the following items at engine start, if possible.
• Malfunction indicator lamp ----- Operation “Malfunction Indicator Lamp (MIL) Check”
• Transmission warning light ----- Operation “Transmission Warning Light Check (Non-Euro-
OBD model)”

smooth and even color smear is indicated, plate should
be reused. If severe heat spot discoloration or surface
scuffing is indicated, plate must be replaced.
Brake return spring subassembly
Measure free length of each brake return springs.
Evidence of extreme heat or burning in the area of clutch
may have caused springs to take heat set and would
require their replacement.
