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
"Freeze frames" are the momentary operating conditions that are recorded to memory when a fault occurs. Only "freeze frames" of a fault are recorded to memory. If no fault has been recorded, the "freeze frames" of the first fault are recorded. If a special fault occurs (misfire or a fault in the fuel supply system), the faults already recorded are overwritten. If an additional fault is recognized, the freeze frames of the first special fault remain in memory. These freeze frames are only displayed by the scan tool.
The following operating conditions are recorded:
- Trouble code of fault which initiated storage of freeze frame data
- Oxygen sensing status, Bank 1
- Oxygen sensing status, Bank 2
- Load value
- Engine temperature
- Oxygen sensing value FR, Bank 1
- Adaptation value FRA, Bank 1
- Oxygen sensing value FR2, Bank 2
- Adaptation value FRA 2, Bank 2
- Engine speed
- Vehicle speed

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
