  • Failed evaporative emission control system
  • Failed air-fuel ratio control system
  • Failed ignition system
  • Improper compression pressure
  • Failed intake and exhaust air system

DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE diagnosis code
Is the diagnosis code set?
Inspection chart for diagnosis code (Refer to ).
Go to Step 2.
 
STEP 2. Check engine oil
  • engine oil check (Refer to GROUP 12 - On-vehicle Service - Engine Oil Check ).
note
  • The overfilling of engine oil, or oil dilution due to an injector malfunction or short distance travelling in the cold condition may cause the oil level to be high.
  • Oil rise, oil fall, or increase of oil consumption due to the malfunction of the crankcase emission control system may cause the oil level to be low.

STEP 7. Check injector for operating sound.
  • Check injector for operating sound (Refer to ).
Is operating sound audible?

Check Inspection Procedure - ignition timing deviation (Refer to ).
 
STEP 9. Visual check of ignition spark.
  • Remove the spark plug and install it to the ignition coil.
  • Connect the ignition coil connector.
  • Disconnect all injector connectors.
  • At the engine start, check each spark plug produces a spark.
Is the check result normal?
Go to Step 10.
Check Inspection Procedure - ignition circuit system (Refer to ).
