INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand−held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was
running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean or rich, as well as other
data from the time when a malfunction occurred.
