At this time, always keep CONSULT connected to the vehicle, and check diagnostic results in real time.
If two or more DTCs are detected, refer to SEC-115, "DTC Inspection Priority Chart" and determine trouble diagnosis order.
NOTE:
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC Confirmation Procedure.
6.PERFORM BASIC INSPECTION
Perform SEC-7, "Pre-Inspection for Multi-System Diagnostic".
Inspection End.
7.DETECT MALFUNCTIONING SYSTEM BY SYMPTOM TABLE
Detect malfunctioning system according to following symptom tables based on the confirmed symptom in step 4, and determine the trouble diagnosis order based on possible causes and symptoms.
8.DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
