The engine auto diagnosis in a Citroen Xsara Picasso is performed by an on-board diagnostic system (OBD) that includes a control unit, sensors, and actuators. Once the system is activated, it performs specific diagnostic tests and checks the engine's functioning to identify any faults or potential issues. The control unit analyzes the data collected from the sensors, compares it to predefined parameters and stored data, and displays any diagnosed issues on the vehicle's dashboard or through a diagnostic tool.
The purpose of the engine auto diagnosis feature is to assist in detecting problems early on, allowing drivers to take appropriate actions and address any necessary repairs or maintenance. It helps to avoid more significant issues and promotes the smooth and efficient operation of the vehicle's engine.
