The OBD port on the old Jetta is located above the clutch pedal. Open the cover outside the fuse box, and you'll find it on the right side of the fuse box base. Here's some relevant information about the OBD interface: 1. OBD, as an abbreviation for a proprietary term, stands for On-Board Diagnostics, which means vehicle self-diagnosis system in Chinese. 2. 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 will determine the specific fault based on specific algorithms and store the diagnostic trouble code in the system's memory. 3. 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.
