INSPECTION PROCEDURE

HINT:  Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool. Because freeze frame records the engine conditions when the
malfunction is detected, when troubleshooting it is useful for determining whether the vehicle was running or stopped, the engine warmed up or not, the
air-fuel ratio lean or rich, etc. at the time of the malfunction.
