Diagnostic Trouble Codes, known as DTCs, are alphanumeric codes that a vehicle’s computer outputs when it detects a malfunction. These codes are transmitted by a vehicle’s On-Board Diagnostics (OBD) system and can be accessed using a diagnostic scanner that connects to the OBD connector. Every vehicle manufactured after 1996 is equipped with an OBD-II computer—the modern OBD system.

Vehicles today are capable of relaying thousands of diagnostic trouble codes to anyone with the equipment to read them. Some vehicles like the Toyota Prius have more than 27 Electronic Control Units on board.
