Where is the OBD interface located on the Changan Ono?

The OBD interface of the Changan Ono is located under the left side of the steering wheel, behind the plastic cover. The Changan Ono features stylish appearance, spacious interior, easy handling, efficient power, and front-engine rear-wheel drive. Here is the relevant introduction: 1. Introduction: OBD stands for On-Board Diagnostics in Chinese, specifically "OBD-II", which is the abbreviation for On-Board Diagnostics Type II. The OBD system continuously monitors the engine's operation to check if the vehicle's emissions exceed the standard. If they do, it will immediately issue a warning. When a fault occurs in the system, 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. 2. Design of the Procedure: The design of the OBD-II procedure aims to avoid confusion between systems. This not only requires the use of a standard 16-pin diagnostic interface but also specific coding and descriptions of components in the manufacturer's documentation. Every vehicle is equipped with a standard-shaped and sized 16-pin diagnostic interface, with the same signal allocation for each pin and located in the same position, installed under the dashboard, somewhere between the left side of the dashboard and 300mm to the right of the vehicle's centerline. It should be noted that certain terminals of the diagnostic interface are designated for specific signals as shown in the appendix. Other terminals can be used by the manufacturer or are not currently used in the current model.
I've used the OBD port on my Changan Honor several times. It's located slightly to the left below the steering wheel. When you're seated properly while driving, move your leg aside and bend down to look, and you'll find a rectangular interface box embedded in the lower left corner of the dashboard. This is where I usually start when connecting a code reader to check for faults—it's quite simple, so don't worry about not finding it. Just note that the spot is a bit dark, so I recommend using your phone's flashlight for better visibility. The OBD port is crucial as it allows real-time monitoring of the engine's condition, helping to prevent minor issues from escalating. For example, it can alert you to abnormal fuel consumption or excessive emissions. Regular checks are beneficial for your car's health, but always ensure the engine is off before operating to avoid electric shocks.
