\nThe Jaltest JDC221A is the cable that ST14D-connector from the security port in Iveco trucks convert to the standard 16-pin OBD2-connection. You do not connect it to the vehicle diagnostic connection on, but directly onto the connector of the security gateway, so that diagnostics do not run through the security port. On the other side, your Jaltest diagnostic cable.\n
\nBehind that gateway lies the complete vehicle network of the heavy-duty Iveco range. Once the connection is established, the equipment accesses the engine control unit and other systems EDC MD1 with Denox 6-HD, the brake control BSM, the body control module BCM, the gearbox Hi-TroniX TraXon and predictive driveline control E-HORIZON. The cable is part of Jaltest CV (commercial vehicles).\n
