Diagnostic Information and Procedures

Self-Diagnosis Function

S6JB0AA504002

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 area 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 light 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 Introduction

S6JB0AA504003

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 Check

S6JB0AA504004

Step

Action

Yes

No

1

1) Record details of the problem. For your record, use of a 

questionnaire form will facilitate 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.

3

1) Inspect and repair basic parts referring to “Keyless Start 

System Symptom Diagnosis”.

Is there faulty condition?

Repair or replace 
malfunction part(s), and 
go to Step 5.

Go to Step 4.

4

1) Check for intermittent problems referring to “Intermittent 

and Poor Connection Inspection in Section 00”.

Is there any faulty condition?

Repair or replace 
malfunction part(s), and 
go to Step 5.

Go to Step 5.

5

1) Confirm if the problem is solved and the keyless start 

system is free from any abnormal conditions. If what has 
been repaired is related to the DTC, clear the DTC once 
and then confirm that no DTC is indicated.

Is there any problem symptom, DTC or abnormal condition?

Go to 2) of Step 1 and 
perform trouble 
diagnosis again.

End.
