Freeze Frame Data
Snapshot of sensor readings recorded when a fault occurs.
Freeze frame data captures engine speed, temperature, and load at the moment a DTC is triggered. It helps technicians analyze fault conditions and identify patterns. Reviewing freeze frame data reduces guesswork and prevents unnecessary parts replacement. Stored in ECU memory, it's retrievable using diagnostic tools. Accurate interpretation leads to faster, data-driven diagnostics and improved repair efficiency.
