Where is the OBD interface on the X-Trail?

[McAbel]

The OBD interface of the X-Trail is located below the steering wheel, slightly towards the driver's side, about 5cm to the right of the fuse box, facing downward. You'll need to position your head close to the foot mat to see it. OBD stands for On-Board Diagnostics, which translates to the vehicle's onboard self-diagnosis system in Chinese. More detailed information is as follows: 1. This system can monitor the working conditions of the engine's electronic control system and other functional modules of the vehicle in real-time during operation. If any abnormal conditions are detected, it identifies specific faults based on specific algorithms and stores them in the system's memory in the form of Diagnostic Trouble Codes (DTC). 2. The useful information obtained from the system's self-diagnosis can assist in vehicle maintenance and repair. Technicians can use the vehicle's original specialized equipment to read the fault codes, enabling quick fault localization for vehicle repairs and reducing manual diagnosis time.
