A diagnostic trouble code (DTC) is a short code your car's computer stores when it detects a problem - it starts with P (powertrain), B (body), C (chassis), or U (network), followed by four digits. You'll usually find yours by having the code read at an auto parts store, or with an OBD2 adapter and an app like DriveHub.
