Step 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 a inspection form will facilitate collecting information to the point required for proper
analysis and diagnosis.

Customer problem inspection form (example)

NOTE
The form is a standard sample. It should be modified according to conditions characteristic of each
market.

11 ) Final confirmation test

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 them by referring to “DTC Clearance”. 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 Step 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, recheck DTC according to “DTC Confirmation Procedure” described in each DTC flow.

Step 6 and Step 7. Recheck and Record of DTC / Freeze Frame Data
Refer to “DTC Check” for checking procedure.

Step 8. A/T Basic Check and A/T Trouble Diagnosis
Perform A/T basic check 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 and 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 A/T is free from any abnormal conditions.
If what has been repaired is related to the malfunction DTC, clear the DTC once, set conditions under which DTC was
detected and A/T and/or vehicle was repaired and confirm that no DTC is indicated.

Malfunction Indicator Lamp (MIL) Check (E-OBD model)

S6JB0B5104002

Refer to “Malfunction Indicator Lamp (MIL) Check in Section 1A”.

Transmission Warning Light Operation Check (Non-E-OBD model)

S6JB0B5104051

1) Turn ignition switch ON.
2) Check that transmission warning light lights for about 2 – 4 sec. and then goes OFF. If anything faulty is found,

advance “Transmission Warning Light Circuit Check – Light Does Not Come “ON” at Ignition Switch ON (Non-E-
OBD model)” or “Transmission Warning Light Circuit Check – Light Remains “ON” at Ignition Switch ON (Non-E-
OBD model)”.

“POWER” Lamp Operation Check

S6JB0B5104052

1) Turn ignition switch ON.
2) Check that “POWER” lamp lights for about 2 – 4 sec. and then goes OFF.

If anything faulty is found, advance to ““POWER” Light Circuit Check – Light Does Not Come “ON” at Ignition
Switch ON”.
