The Jaltest JDC502A is a diagnostic adapter cable designed to connect diagnostic equipment with Steyr internal combustion engines. The cable features a specific 6-pin connector on the vehicle side and a standardized 16-pin OBD2 connector on the other end for connection to a diagnostic interface, such as the Jaltest Link. This enables a stable and reliable communication link for performing diagnostic tasks.
This cable is developed for use in environments where Steyr engines are applied, such as in agriculture, the construction sector, and stationary applications.
