Where is the OBD interface located in the Santana?

The OBD interface of the Santana is located under the steering wheel, directly above the left foot, slightly towards the steering wheel shaft, and the pink connector is the OBD interface. OBD stands for On-Board Diagnostics, which translates to "on-board self-diagnostic system" in Chinese. This 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. When a system malfunction occurs, the Malfunction Indicator Lamp (MIL) or Check Engine warning light will illuminate, and the Powertrain Control Module (PCM) will store the fault information in memory. The fault code can be read from the PCM through a specific procedure. Based on the fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault. OBD monitors the engine, catalytic converter, particulate filter, oxygen sensor, emission control system, fuel system, EGR, and other systems and components in real-time. Then, through various emission-related component information, it connects to the ECU [Electronic Control Unit, which can detect and analyze emission-related faults]. When an emission fault occurs, the ECU records the fault information and related codes, and issues a warning through the fault light to inform the driver. The ECU ensures access to and processing of fault information through a standard data interface.
