The OBD interface of the 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 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.

The OBD interface of Honor is actually quite fixed in position, generally located at the left edge area directly below the steering wheel on the driver's side. When you get into the car and lean back, you can feel a flat slot near the foot pedal with your hand. The OBD interface is designed to be hidden but practical, capable of reading engine data when connected to external devices. I often use it to diagnose issues like unstable idling or the reason for the check engine light. By the way, it's placed there for safety and convenience, so don't attempt to modify the wiring to avoid interfering with its function. Pay attention to this small detail during daily driving to prevent panic when a fault occurs.

The OBD interface of the Honor is located on the left side under the steering wheel. Just sit in the car, look down, and you'll find a black socket there. For regular vehicle performance checks, simply plug in the tool—no need to complicate things.

When I first drove the Ono, I also didn't know where the OBD interface was. Later, I found it near the left foot on the lower left side of the steering wheel. Just bend down slightly and you'll see a square interface embedded in the plastic panel. Its dark color makes it easy to miss. Connecting a diagnostic device to it allows you to check fault codes for maintenance, such as determining why the air conditioning isn't cooling or why there's a power drop. It's recommended for beginners to familiarize themselves with the manual's location diagram before attempting to use it.

The OBD interface of Honor is usually located below the steering wheel, slightly to the left. You can find it by bending down and feeling around near the foot pedals when seated. This location is well-chosen, avoiding driving interference while remaining easily accessible. Once connected to diagnostic equipment, it can identify vehicle issues such as excessive carbon buildup or faulty sensors. For routine maintenance, simply plugging and unplugging is hassle-free and convenient.
