The Jaltest OHW is a complete diagnostic system for earthmoving and heavy equipment: a case containing the Jaltest Link, the unit you connect to the diagnostic socket, and the software that runs on your own laptop.
With it, you can access the control units of excavators, wheel loaders, dump trucks, cranes and compact machines, as well as stationary engines. Cojali divides coverage into three lists: 99 heavy equipment manufacturers, 87 compact equipment manufacturers and 30 engine manufacturers. A new software version is released three times per year, with additional manufacturers, models and systems.
This set includes everything required to perform diagnostics: the Link, the software activation and the software licence for the first year. Once you receive the unit, we will activate the module based on the serial number of the supplied Link. You will need to arrange a laptop and the manufacturer-specific cables separately.
