What Is Freeze Frame Data and Can the YOUCANIC Scanner Display It?

Freeze Frame Data is a snapshot of key engine and vehicle parameters recorded by the ECU at the exact moment a diagnostic trouble code (DTC) is stored. It helps you understand the conditions under which a fault occurred.

What Freeze Frame Typically Includes

• Engine RPM at time of fault
• Vehicle speed
• Coolant temperature
• Fuel trim values
• Engine load
• Intake air temperature

Why It Is Useful

Freeze frame data tells you when and under what conditions the fault occurred. For example, a misfire code with freeze frame showing high RPM and high load suggests a different root cause than one at idle and cold start.

Is My Vehicle Supported?

Freeze frame data is available on virtually all OBD-II vehicles (1996+). The YOUCANIC scanner displays freeze frame data when reading fault codes.
