Understanding these codes is essential for effective troubleshooting. While the tool itself might provide a brief description of the code, further research is often necessary to fully understand the underlying issue. Online resources and repair manuals can provide detailed information on DTCs and their possible causes.

Decoding the DTC Structure

A typical DTC consists of a letter followed by four digits. The letter indicates the system where the fault lies (e.g., P for powertrain, B for body, C for chassis, U for network). The digits provide more specific information about the nature of the fault. For example, P0302 indicates a misfire in cylinder 2.
