The Jaltest JDC544A is the diagnostic cable that connects the 8-pin diagnostic connector of Hyster forklifts to the Jaltest Link. On the vehicle side, there's the 8-pin connector located in the operator's cabin of the forklift; on the interface side, the cable runs to the 16-pin OBD2 port of your Jaltest diagnostic cable. This connector is found on models equipped with EControls engine management, the control system for LPG and gasoline engines.
Behind this single connector lie two control units: The EControls ECM 4G engine controller for LPG and gasoline versions and the VECU, the truck's central vehicle computer. Through the Jaltest software, you can read fault codes, live data and maintenance information from the engine controller; and fault codes and live data from the VECU. The cable falls under Jaltest MHE (Material Handling Equipment) and Jaltest OHW (Off-Highway machines).
