This system continuously monitors the engine's operating conditions to check if the vehicle's emissions exceed standards. If they do, it will immediately issue a warning. When the system detects a fault, the malfunction indicator lamp or check engine warning light will illuminate, and the Powertrain Control Module will store the fault information in memory. The fault code can be retrieved through a specific procedure. Based on the fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault. The useful information obtained from the system's self-diagnosis can assist in vehicle maintenance and repairs. Technicians can use the manufacturer's specialized equipment to read the fault codes, enabling rapid fault localization for efficient vehicle repairs and reducing manual diagnosis time.
