Understanding Diagnostic Trouble Codes (DTCs)
Diagnostic Trouble Codes (DTCs) are alphanumeric codes that represent specific malfunctions within your vehicle’s systems. A vehicle computer scan tool retrieves these codes, which can then be used to pinpoint the source of the problem.
Decoding DTCs
DTCs follow a standardized format, consisting of a letter and four numbers. For instance, the code P0302 indicates a misfire in cylinder 2. Understanding these codes is essential for accurate diagnosis.
