The Jaltest JDC536A is a diagnostic Adapter Cable designed to connect the Jaltest Link Interface with the specific 12-pin diagnostic port of Komatsu machines. This cable converts the vehicle-specific connector to a standard 16-pin OBD2 connector, enabling communication with the machine's electronic systems. The cable is developed for use in demanding environments, such as construction and mining, and is suitable for performing diagnostics and maintenance on off-road and construction machines.
With this cable, the Jaltest OHW (Off-Highway) software can perform a full system scan on compatible Komatsu vehicles. This provides access to functions such as reading and clearing fault codes, viewing live data from sensors and actuators, performing system calibrations, and configuring parameters. The connection enables diagnostics of systems such as engine management, hydraulics, transmission, and other control units.
