Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Freeze Frame Data: Notes
When a DTC is stored, ECM will also record and store engine operating conditions when malfunction occurred. This information is referred to as freeze frame data. Freeze frame data will be stored in ECM memory until cleared, with the exception of the occurrence of an engine misfire or fuel trim malfunction. When a misfire of fuel trim fault occurs, freeze frame data will be updated with the most current information regarding these failures. Freeze frame data cannot be accessed using MIL.
