Engine Basic InspectionS7RS0B1104009
This check is very important for troubleshooting when ECM has detected no DTC and no abnormality has been found
in “Visual Inspection”.
Follow the flow carefully.Step Action Yes No 1 Was “Engine and Emission Control System Check”
performed? Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2 Check battery voltage
Is it 11 V or more? Go to Step 3. Charge or replace
battery.
3 Is vehicle equipped with keyless start control system? Go to Step 4. Go to Step 5.
4 Check keyless start control system malfunction
1) Check keyless start control system referring to “Keyless
Start System Operation In spection in Section 10E”.
Is check result satisfactory? Go to Step 5. Keyless start control
system malfunction.
5 Is engine cranked? Go to Step 6. Go to “Cranking System
Symptom Diagnosis in
Section 1I”.
6 Does engine start? Go to Step 7. Go to Step 9.
7 Check idle speed
1) Warm up engine to normal operating temperature.
2) Shift transmission to neutral position for M/T (“P” position
for A/T).
3) Make sure that all electrical loads are switched off.
4) Check engine idle speed with scan tool.
Is it 650 – 800 r/min.? Go to Step 8. Go to “Engine Symptom
Diagnosis”.

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.
