The Jaltest JDC516A is the adapter cable that converts the proprietary 4-pin diagnostic connector found on Landini tractors to the standard 16-pin OBD2 interface. On the vehicle side, the 4-pin connector plugs into the diagnostic port in the cab, while the interface side features the 16-pin OBD2 inlet for your Jaltest diagnostic cable.
Through this adapter, your diagnostic equipment connects to the vehicle network and accesses the ECM 1100C (Tier 2 / Stage II) electronic diesel control, the engine management system fitted across all these model ranges. On the Powerfarm series, you'll also reach the transmission control unit TRANS (Sauer Danfoss) and the instrument cluster, while Jaltest on the Legend series provides engine management access only. Since agricultural vehicles aren't subject to mandatory OBD regulations, Landini retained this proprietary connector across many production years. This cable falls under Jaltest AGV (agricultural vehicles).
