Where is the OBD interface located on the Grand Commander?

OBD interface is located near the driver's left foot position. OBD introduction: OBD stands for On-Board Diagnostics system. This system continuously monitors the engine's operating conditions to check if the vehicle's emissions exceed standards. If they do, it will immediately issue a warning. When a system malfunction occurs, the malfunction indicator light or check engine warning light will illuminate, and the powertrain control module (PCM) will store the fault information in memory. The fault codes can be read from the PCM through specific procedures. Based on the fault codes, maintenance personnel can quickly and accurately determine the nature and location of the fault. OBD working principle: OBD connects various emission-related component information to the Electronic Control Unit (ECU), which has the capability to detect and analyze emission-related faults. When an emission fault occurs, the ECU records the fault information and related codes, and alerts the driver through the malfunction indicator light. The ECU ensures access to and processing of fault information through a standard data interface.
To be honest, as an ordinary person who frequently researches automotive issues, I've found that the OBD port location on the Grand Commander is quite standard—it's positioned beneath the driver's seat, near the knee area to the left of the steering wheel. There's a small cover panel that can be easily opened with a gentle push. The OBD serves as the connection point for the vehicle's diagnostic system, primarily used to plug in a scanner for reading fault codes, such as checking the cause of an illuminated engine light or conducting emission tests. Locating it before driving helps avoid difficulties when parked; its fixed position is advantageous for DIY maintenance. If you're unsure about the direction, try crouching down and looking toward the inner side of the driver's seat—usually, a black connector is visible. It's best to note it in the manual or take a photo for reference to prevent any last-minute search that might disrupt your travel plans.
My experience comes from my own Grand Commander. The OBD port is located near the driver's feet, behind the small cover below the steering wheel. The first time I used it was to save money by diagnosing issues myself – it's quite simple: turn the key to the ON position, plug in a tool, and you can read fault data. The location makes sense, as it's close to the driver's seat for easy access without distracting from driving. During routine maintenance, check if the port is loose or dusty, as long-term neglect can lead to poor contact. For more details, search online tutorials or owner forums where people often share picture guides. If you can't find it, don't worry – dealerships can quickly locate it for you.
