Interpreting Freeze Frame Data Modern scanners do more than just list codes; they capture contextual information known as freeze frame data. By commanding a specific part to operate and observing the results, the technician can confirm functionality and rule out electrical wiring issues as the root cause of the scanner engine codes.

Each code is structured into five characters, beginning with a letter that defines the system at fault. The Role of the OBD-II Port The retrieval of scanner engine codes is made possible through the On-Board Diagnostics II, or OBD-II, port.
Mandated in vehicles manufactured after 1996, this standardized connector allows a handheld scanner or software interface to communicate with the vehicle’s ECU. This functionality enables active testing of components like fuel injectors, cooling fans, and actuators without manual intervention.
