Universal · OBD cables
Set of physical adapter cables with different round and rectangular sockets used for diagnostic connections in trucks and buses.
The exact plan and total amount will be shown again at the payment step.
Verify the vehicle's make, model, year, and physical diagnostic socket; the input for the VCI cable to be used, and the device's 12/24 V compatibility before ordering.
Product information
This product is not a diagnostic device; it is an adapter set that connects different heavy-duty vehicle sockets to a compatible main device. Four source photos show the physical form of the set; the number of cables per brand and exact pin mapping are confirmed separately with the delivered set.
Physical Connection Coverage
Connecting the cable, adapter, or communication module to the vehicle does not prove that the vehicle is supported by the software. The physical connector, pin layout, main device, and vehicle software must be compatible simultaneously.
Product details
Actual product images show multiple round and rectangular heavy-duty vehicle connectors, short adapter cables, and common device-side connections. The arrangement in the image does not mean that each cable works with all brands.
Product details
The 24 V electrical system is common in trucks and buses. The cable does not reduce voltage or make the device compatible with 24 V. The voltage supported by the VCI used, communication protocol, and software package must be checked via the manufacturer's documentation.
Product details
Upon order delivery, the number of adapters, the body of each connector, pins, and labels are compared with the gallery. If there is a missing or different part, it is recorded with a photo before energizing the vehicle. Software, VCI, and computer are not part of the set.
Product details
Each adapter should be labeled with its number or socket definition after use and stored in a separate compartment where its pins are not exposed. Oil, brake cleaner, and pressurized metal particles should be kept away from connectors. Cables are not connected in a tight loop; heavy plugs are placed so as not to load the cable body.
This reduces the mixing of similar round sockets and the selection of the wrong adapter during field use.
Product details
At vehicle intake, the make, model, year of manufacture, and engine information are recorded first; then, the diagnostic socket's location is found and its cover is opened. Because the outer diameter, keyway, and pin arrangement of round sockets can be similar, adapters are not selected based on the brand logo alone.
The candidate cable in the set is aligned in front of the socket without energizing; it is expected to fit without force and without gaps. It is documented that the main device is suitable for the 24 V input and supports the relevant vehicle family in the software. After the correct adapter is connected, the first operation is to read the control unit list.
If there is doubt about the power supply, CAN line, or pin direction, the electrical diagram is checked before changing the adapter.
Product details
When the set arrives at the service, a group photo is not sufficient. Each adapter is numbered individually; the front and side view of the vehicle-side socket, the device-side connection, the label, and the cable body are recorded. The four angles in the gallery are compared with the delivered physical parts.
If there is a cracked body, bent pin, or loose cable gland, that part is set aside without use. Which adapter was successfully tested on which vehicle is added to the service inventory; this record reduces the possibility of installing the wrong cable in the future.
Since the set does not convert a non-supported passenger car VCI into a heavy-duty vehicle device, the main device's voltage and protocol limits are kept visible for each work order.

FAQ
No. Compatible 12/24 V heavy-duty VCI hardware, software/license, and vehicle coverage are required.
No. Physical socket, pin layout, vehicle system, main device, and software support vary by brand-model.
Images show different adapters; however, as variations may change, the exact quantity must be confirmed in the order record and pre-shipment check. A part not visible in the image is not assumed to exist.
It should only be connected when the VCI used and the selected adapter are suitable for the 24 V system. The cable set alone does not convert voltage or protect the device.
No. The sale is for the cable/adapter set; diagnostic interface, computer, software license, and brand coverage are required separately.
