Where is the diagnostic connector of Haval H3?
2 Answers
The diagnostic connector of Haval H3 is located in the interior trim panel below the steering wheel, near the driver's knee area. Pin configuration of automotive diagnostic connector: Pin 16 is positive power supply, pin 4 is ground, pin 7 is the data diagnostic line (typically for engine testing). Other pins serve as data diagnostic lines for various vehicle functions including ABS system, airbag system, automatic transmission system, etc. Working principle: Features manual fault code reading and clearing functions. Compact design for portability, simple operation, and high cost-effectiveness. Specifically designed for vehicle owners or drivers with precise compatibility. Users connect this device to the vehicle's diagnostic port, then manually operate its buttons to read or clear fault codes from the electronic control systems.
Last time I helped my neighbor locate the diagnostic port on his Haval H3, the older models always dangle under the steering wheel. You have to semi-recline into the driver's seat and crane your head toward the accelerator pedal area—the thing sits on the left side of the steering column, covered by a black plastic cap. Remember that the 2010 batch had wider ports with pins changed from white to light blue, and the letters 'DIAGNOSTIC' were embossed beside the port. Better not randomly unplug it yourself to read trouble codes—dealership technicians warned that poor contact may trigger false faults. Pro tip: ask the mechanic to clean the port contacts during routine maintenance.
