Brand: SAE
SAE A502 is a standard created by the Society of Automotive Engineers (SAE) that specifies the performance and control methods required for an engine's electronic control system (ECS) in heavy-duty commercial vehicles. The standard aims to ensure the reliability, durability, and safety of ECS in such vehicles, which are subjected to more extreme operating conditions and higher loads compared to passenger cars. SAE A502 covers various aspects of ECS, including fuel injection, ignition timing, airflow, and emissions control, as well as diagnostic and testing procedures. It also outlines requirements for compatibility with other systems in the vehicle and with other ECS in the fleet. Compliance with SAE A502 is mandatory for ECS used in heavy-duty commercial vehicles, and it helps to ensure interoperability and predictable performance across different manufacturers and applications.
