Where is the diagnostic port on the C4L?

[VonCecilia]

The OBD interface (diagnostic port) of the C4L is located under the small box in front of the gear shift lever. You can access the OBD interface by removing this small box. Here is some information about the OBD interface: 1. The OBD interface is a relatively important port in a car, which can be connected to a diagnostic computer. After connecting to the diagnostic computer, you can read fault codes, access the car's data stream, and even modify the ECU program. 2. The OBD interface is generally located near the driver's pedal area. When using the car, be careful not to let mud or sand enter the OBD interface, and avoid exposing it to water. Some cars require a specialized computer to read data, and a generic computer may not be able to access the data. For such vehicles, you will need to visit a 4S shop to use a specialized computer for data reading.
