Understanding Your Car’s Language
Think of your car’s computer system as its brain, constantly monitoring various systems and sensors. When something goes wrong, it logs a Diagnostic Trouble Code (DTC) in its memory. An OBD2 scanner acts as the interpreter, translating these codes into understandable terms.
These codes, often starting with a letter like “P” for powertrain or “C” for chassis, followed by four digits, provide specific clues about the issue. For example, P0420 indicates a problem with the catalytic converter system.
