Freeze-Frame Data

WARNING: This page is about a different car, the 1995 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

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.
