DTC Fault Code

DTCs notify users if there's a certain issue in your vehicle. Each code corresponds to a particular issue in a vehicle. A corresponding dtc fault code is activated once vehicle trouble is detected.

Diagnostic Trouble Codes (DTC) are categorized into 4 main systems and they are started with 4 different letters (P-U-B-C). The first letter in the DTC corresponds to the type of system that relates to the trouble code.

In most cases, you will see a 'P' that indicates a powertain issue, which includes a vehicle's engine, emission, and transmission systems. 'B' codes signal body issues, such as problems with climate control, lighting, or airbags. 'C' codes point to chassis problems, including braking, steering, or suspension issues, and 'U' codes indicate network communication errors, such as wiring problems.
