The Jaltest JDC549.9 is the diagnostic cable that connects the 4-pin diagnostic connector of JLG and Haulotte aerial work platforms and telehandlers to the Jaltest Link. On the machine side, the 4-pin connector is located on JLG units behind the battery cover next to the control panel at ground level; on the interface side, a 26-pin DB26 plug connects directly into the Jaltest Link, eliminating the need for a separate 16-pin adapter cable.
The cable opens the diagnostic line to the hydraulic control and engine control systems of the machine. On the hydraulic side, this includes HYDRAULICS from JLG scissor lifts and HYDRAULICS (CAN) from Haulotte aerial platforms; on the engine side, Deutz controls EMR2 through EMR5, Kubota E-CDIS, Kohler controls, and EControls ECM 4G from gasoline and LPG models. The full feature set is available with scissor lifts; on larger JLG boom lifts, HYDRAULICS is available without supported functions. This cable falls under Jaltest MHE (Material Handling Equipment).
