OBD2 Cable

A cable with a small on-board computer that lets you connect a laptop or other device to your van's ECU for diagnostic purposes. The software on your computer can communicate with the van's management system to discover detected faults, run tests, view live stats on your running engine, and more.

There are many systems available for performing diagnostics on your van, some of which have greater abilities than others. This cable variety requires a computer with appropriate software.

To use, just plug the USB end into the computer, then plug the OBD2 end into the van's OBD2 port, which is usually below the steering wheel. What to do next will depend on the software on your computer. You can find guides for most software online.
