4Check keyless start control system malfunction
1) Check keyless start control system referring to “Keyless
Start System Operation Inspection in Section 10E”.
Is check result satisfactory?Go to Step 5. Keyless start control
system malfunction.
5Is engine cranked?Go to Step 6. Go to “Cranking System
Symptom Diagnosis in
Section 1I”.
6Does engine start?Go to Step 7. Go to Step 9.
7Check idle speed
1) Check engine idle speed referring to “Idle Speed and
IAC Throttle Valve Opening Inspection”.
Is check result as specified?Go to Step 8. Go to “Engine Symptom
Diagnosis”.
8Check ignition timing
1) Check ignition timing referring to “Ignition Timing
Inspection in Section 1H”.
Is check result as specified?Go to “Engine Symptom
Diagnosis”.Check ignition control
related parts referring to
“Ignition Timing
Inspection in Section
1H”.
9Check immobilizer system malfunction
1) Check immobilizer indicator lamp for flashing.
Is it flashing when ignition switch is turned to ON position?Go to “DTC Check in
Section 10C”.Go to Step 10.
10Check fuel supply
1) Check to make sure that enough fuel is filled in fuel tank.
2) Turn ON ignition switch for 2 seconds and then OFF.
3) Repeat Step 2) a few times.
Is fuel pressure felt from fuel feed hose when ignition switch
is turned ON?Go to Step 12. Go to Step 11.
11Check fuel pump for operation
Was fuel pump operating sound heard from fuel filler for
about 2 seconds after ignition switch ON and stop?Go to “Fuel Pressure
Check”.Go to “Fuel Pump and
Its Circuit Check”.
12Check ignition spark
1) Check ignition spark referring to “Ignition Spark Test in
Section 1H”.
Is it in good condition?Go to Step 13. Go to “Ignition System
Symptom Diagnosis in
Section 1H”.
13Check fuel injector circuit
1) Check fuel injector circuit referring to “Fuel Injector
Circuit Check.”
Is it in good condition?Go to “Engine Symptom
Diagnosis”.Go to “Fuel Injector
Circuit Check”. Step Action Yes No
