Step 1. Customer Complaint Analysis
Record details of the problem such as failure, complaint and how it occurred as described by the customer.
For this purpose, use of such an inspec tion 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.

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 fa ilure 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 step s of customer complaint analysis, trouble symptom
confirmation and/or A/T basic check) and re pair or replace faulty parts, if any.
Step 9. Troubleshooting for DTC
Based on the DTC indicated in Step 6 / 7 and referring to “a pplicable 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 vehicl e 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.

Diagnostic Information and Procedures
Precautions in Diagnosing TroublesS7RS0BA504001
• The keyless start system executes data transmission/reception by means of th e radio wave. Therefore,
proper operation may not be obtained if use of the
door lock function and engine start function of the
keyless start system is attempted near the place
where strong radio wave is emitted (TV and radio
broadcasting stations, etc.).
• Diagnostic information stored in keyless start control
module memory can be checked only by key indicator
lamp.
• Be sure to use the trouble diagnosis procedure as described in “Keyless Start System Check”. Failure to
follow it may result in incorrect diagnosis. (Some other
DTC may be stored by mistake in the memory of
keyless start control module during inspection.)
• Be sure to read “Precautions for Electrical Circuit Service in Section 00” befo re inspection and observe
what is written there.
• Communication of ECM, BCM, TCM (A/T model), ABS control module, keyless start control module and
combination meter is estab lished by CAN (Controller
Area Network). (For detail of CAN communication for
keyless start control module, refer to “CAN
Communication System Description”). Therefore,
handle CAN communication line with care referring to
“Precaution for CAN Communication System in
Section 00”. • Replacement of the keyless start control module
When keyless start control module is replaced with
new one, make sure that r egister remote controller ID
code to keyless start co ntrol module correctly
according to “Registration Procedure for Remote
Controller ID Code”.
• Keyless start control module substitution When the keyless start control module used in
another vehicle was installed in the vehicle, register
the ID code of the remote controller in the keyless
start control module as well as the ignition key
transponder code fo r the immobilizer control system in
ECM. For the registration procedure of the ignition key
transponder code, refer to “Registration of the Ignition
Key in Section 10C”.
Self-Diagnosis FunctionS7RS0BA504002
The keyless start control module has self-diagnosis
function to monitor the system components and circuits
while the keyless start system is at work. When the
keyless start control module detects an abnormality in
the system, it saves the ar ea where such abnormality
has occurred as a DTC in its memory. The DTC stored in
memory of the keyless start control module is indicated
by the key indicator lamp in the combination meter
flashing in a specific pattern. For DTC indication, refer to
“DTC Check” and for the clearing procedure, to “DTC
Clearance”.
Keyless Start System Diagnosis IntroductionS7RS0BA504003
To ensure that the trouble diagnosis is done accurately
and smoothly, observe “Precautions in Diagnosing
Troubles” and follow “Keyless Start System Check”.
Keyless Start System CheckS7RS0BA504004
Step Action YesNo
1 1) Record details of the problem. For your record, use of a questionnaire form will facilit ate collecting information for
proper analysis and diagnosis.
2) Check if the problem described in “Customer Questionnaire (Example)” actually occurs in the vehicle.
(This step should be performed with the customer if
possible.)
Perform “Keyless Start System Operation Inspection”
procedure to check if the symptom which has occurred is
abnormal or not.
3) Check for DTC referring to “DTC Check”, and then record DTC(s).
4) Clear DTC referring to “DTC Clearance” if any DTC exists, and then recheck for DTC.
Is any DTC still detected? Go to Step 2.
Go to Step 3.
2 1) Check and repair referring to applicable “DTC Table”. Are check and repair complete? Go to Step 5.
Check and repair
malfunction part(s), and
go to Step 5.
