AUTOMATIC TRANSAXLE (M13 ENGINE) 7B1-17
1. Customer Complaint Analysis (See Customer Problem Inspection Form)
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” in this section. If DTC exists, print or write
down DTC/Freeze frame data and then clear malfunction DTC(s) by referring to “DTC Clearance” in this section.
Malfunction DTC indicates malfunction in the system but it is not possible to know from it whether the malfunc-
tion 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 unneces-
sary.
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” in this section.
5. Trouble Symptom Confirmation
Check trouble symptoms based on information obtained in Step 1 Customer Complaint Analysis and Step 2
DTC Check.
Also, reconfirm DTC according to “DTC Confirmation Procedure” described in each DTC Flow Table.

Refer to “DTC Check” in this section for checking procedure.
8. Automatic Transmission Basic Check and Trouble Diagnosis Table

the flow table has been reached, check the parts of the system suspected as a possible cause referring to “Tr ou -
ble Diagnosis Table” 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.
9. Diagnostic Trouble Code Flow Table (See each DTC Flow Table)
Based on the DTC indicated in Step 6/7 and referring to Diagnostic Trouble Code Flow Table in this section,
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.
10. Check for Intermittent Problem

mittent and Poor Connection” in Section 0A and related circuit of DTC recorded in Step 2.
