The Jaltest JDC506A9 connects the 4-pin diagnostic connector of Fendt tractors to the 16-pin OBD2 socket on your Jaltest diagnostic cable. On the machine side, there is a round black plug with a ribbed coupling ring, which you secure to the connector in the cab. Behind the OBD2 socket, the cable splits into two branches: one to that round plug and one shorter branch that terminates in a round power connector. The entire cable measures 28 to 30 cm in length.
Through this connector, the diagnostic equipment accesses the Fendt diagnostic line and thereby reaches far more than just engine management: the GTR transmission, the EHR and EHF lifting equipment and the Comfort onboard computer are all covered, supplemented on the Xylon with the PTO shafts, differential lock and suspended front axle. On the Favorit 900, you additionally reach the engine management EDC MS6.4 with distributor injection pump, whilst Jaltest on the Farmer 400 and Xylon 500 does not provide engine management coverage. This version works with the Jaltest Link V9 and falls under Jaltest AGV (agricultural vehicles).
