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