Is the symptom described?

YES>>

GO TO 7.

NO>>

Monitor input data from related sensors or check voltage of related module terminals using CONSULT.

DETECT MALFUNCTIONING PART BY DIAGNOSIS PROCEDURE

Inspect according to Diagnosis Procedure of the system.

Is malfunctioning part detected?

YES>>

GO TO 8.

NO>>

Check according to Intermittent Incident.
