Fault codes, also known as Diagnostic Trouble Codes (DTCs), are standardized or manufacturer-specific codes that indicate the presence of a malfunction within a vehicle’s electronic control system. In Freightliner trucks, these codes are generated by the Engine Control Module (ECM), Transmission Control Module (TCM), or other electronic subsystems when a fault is detected.
The primary purpose of fault codes is to provide quick and precise identification of issues, enabling technicians to focus their diagnostic efforts efficiently. They serve as a roadmap to understanding what component or system is malfunctioning, facilitating faster repairs and minimizing vehicle downtime.
