CAUTION / NOTICE / HINT
After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click hereНажмите здесь).
Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
