The Jaltest JDC555A is the adapter cable for Still forklifts with the manufacturer's proprietary dual 4+4-pin connector; on the vehicle side you'll find those two connectors, and on the interface side the 16-pin OBD2 port of your Jaltest diagnostic cable. On a Still forklift, the engine side and truck side are located on separate connections under the hood; this cable brings them together into a single port.
Once the connection is established, the Jaltest software reaches both sides of the forklift without any switching. On diesel and LPG trucks, you'll access the engine control units EDC 15 VM, EDC 16 U31, EDC 17 CP20 and the newer EMR4 - EDC 17 CV52/CV54, on gas and LPG models the GCP engine control unit, and on the electric RX 60 series the MCU machine computer. From the hydraulic control unit VR Jaltest reads only measured values and ECU data, not fault codes. The cable falls under Jaltest MHE (Material Handling Equipment).
