DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
• Perform DTC CONFIRMATION PROCEDURE when the fu el is between 1/4 and 3/4 full, and vehicle is
placed on flat level surface.
• Always perform test at a temperature of 5 to 60 °C (41 to 140 °F).
