The OBD interface of the Ford Mondeo is located under the driver's seat. There is a storage compartment, and you can see a diagnostic connector inside after pulling it open. Here is some information about OBD: 1. The OBD system continuously monitors the engine's operating conditions to check if the vehicle's emissions exceed the standard. If they do, it will immediately issue a warning. 2. When a system fault occurs, the Malfunction Indicator Lamp (MIL) or Check Engine warning light will illuminate. At the same time, the Powertrain Control Module (PCM) stores the fault information in memory. The fault code can be read from the PCM through a specific procedure, allowing maintenance personnel to quickly and accurately determine the nature and location of the fault based on the fault code.
