INSPECTION PROCEDURE
HINT
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data
the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary,
if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
