PERFORM DTC CONFIRMATION PROCEDURE

Perform DTC Confirmation Procedure for the displayed DTC, and then check that DTC is detected again.

At this time, always connect CONSULT to the vehicle, and check diagnostic results in real time.

If two or more DTCs are detected, refer to

and determine trouble

• Freeze frame data is useful if the DTC is not detected.

• Perform Component Function Check if DTC Confirmation Procedure is not included in Service Manual. This

simplified check procedure is an effective alternative though DTC cannot be detected during this check.

tion Procedure.
