Step 8: Engine Basic Inspection and Engine Symptom Diagnosis

Perform basic engine check according to the ENGINE BASIC INSPECTION  first. When the end of the flow table has been reached, check the parts of the system suspected as a possible cause referring to ENGINE SYMPTOM DIAGNOSIS  and based on symptoms appearing on the vehicle (symptoms obtained through steps of customer complaint analysis, trouble symptom confirmation and/or basic engine check) and repair or replace faulty parts, if any.
