The Jaltest JDC520A connects the proprietary 16-pin diagnostic connector of a Valtra tractor to the 16-pin OBD2 port of your Jaltest diagnostic equipment. On the machine side, there is a round black plug with a ribbed coupling ring and a metal cable clamp; the contact holder has sixteen numbered positions, of which twelve are fitted with contacts. Despite the equal number of pins, the pin assignment differs from a standard OBD2 connector. The cable measures 28 to 30 cm.
Once connected, the Jaltest software accesses the tractor's engine control unit. Jaltest supports two control modules with common rail fuel injection: the EEM3 - EDC 7 UC31 and the newer EEM4 - EDC 17 CV54, with the EEM4 also offering additional functions. For both control modules, service intervals can be retrieved. The cable is compatible with Jaltest Link V8.1 and V9 and falls under Jaltest AGV (agricultural vehicles).

- Perform additional functions: The extra procedures per control unit, such as reset and calibration functions. Available on Valtra EEM4 - EDC 17 CV54.
