Understanding Autoscan OBD2 Results
Understanding the data retrieved from an autoscan is crucial for accurate diagnosis. The most important information you’ll receive are Diagnostic Trouble Codes (DTCs).

Along with DTCs, you may also receive other data such as freeze frame data, pending codes, and live sensor data.
Interpreting DTCs
Each DTC consists of a five-digit alphanumeric code. The first letter indicates the system where the fault lies (e.g., P for Powertrain, B for Body, C for Chassis, U for Network). The following numbers further specify the nature of the fault. You can use online resources or your scanner’s manual to decode the meaning of each DTC.
