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
The ECM records engine operating condition (fuel system, calculated load, coolant temperature, fuel trim (mixture), engine speed, vehicle speed, etc.) with 1st malfunction ONLY. The information is ONLY for the 1st recorded failure, no matter if more than one code has been recorded. The freeze-frame data is only updated when all codes have been cleared, or a misfire or fuel-trim malfunction has occurred.
