Where is the OBD interface of Haima 323?

Hainan Mazda 323's OBD interface is located under the dashboard, inside the cover above the accelerator pedal. OBD stands for On-Board Diagnostics, which is a detection system extended for automotive fault diagnosis. OBD monitors the engine, catalytic converter, particulate trap, oxygen sensor, emission control system, fuel system, EGR, and other systems and components in real-time. Then, through different emission-related component information, it connects to the ECU (Electronic Control Unit, which can detect and analyze emission-related faults). Below is more related information: How OBD works: 1. The OBD system continuously monitors whether the vehicle's exhaust exceeds the standard during engine operation. If it exceeds the standard, a warning will be issued immediately. 2. When a system failure occurs, the fault (MIL) light 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 certain procedure. 3. Based on the prompt of the fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault.
The OBD interface of the Haima 323 is usually located under the driver's seat, near the dashboard area close to the steering column. You can typically find a small square-shaped slot by crouching down in front of your knees, making it very convenient to connect diagnostic tools. I often encounter this when repairing my car. Haima's design is very user-friendly, with the interface position standardized, so there's no need to worry about damaging other parts. If you're unsure, you can open the car door and use a flashlight to check, or refer to the latter chapters of the user manual, which often include illustrated explanations. Additionally, note that the OBD interface is used for reading vehicle fault codes or system upgrades. If it's covered in dust, you can gently clean it with a cotton swab, but make sure to disconnect the power for safety. Regularly checking the interface condition during maintenance can prevent poor contact issues and extend the car's lifespan, which is much more cost-effective than repairing problems later.
