PassThru vehicle communication interfaces connect OEM software on a computer to a vehicle. SAE J2534 defines a standard software interface, but actual coverage depends on the exact hardware, driver, protocol, OEM application, vehicle and task. This directory covers selected US and European suppliers and includes both current and older equipment.

Before programming
Verify the vehicle manufacturer's exact supported interface, driver and firmware, vehicle and operation, operating system, OEM software, subscription and any required security credentials. Connect the manufacturer-specified stable power supply and follow the OEM programming procedure. DoIP, CAN FD, J2534-1, J2534-2 and other interfaces or protocols are distinct capabilities; one claim does not prove support for all others. Availability and validation vary by region and change over time.
These interfaces provide a communication path; they do not automatically include OEM access or provide the same functions as a dedicated ECU tuning programmer. See also the tuning tools directory and diagnostic scan tools directory.
