Save freeze-frame data before clearing
Freeze-frame data shows operating conditions when a fault was recorded. Save engine speed, load, coolant temperature, vehicle speed, fuel-system status and trims if available. A snapshot may relate to only one fault; it is not continuous recording. Clearing codes may remove it and reset readiness. Never operate a scanner while driving.
