Understanding Car Diagnostic Codes
Before diving into the “how,” let’s understand the “what.” Diagnostic Trouble Codes (DTCs) are standardized alphanumeric codes that represent specific malfunctions detected by your car’s onboard computer. These codes are your car’s way of telling you something’s wrong.
