Tool comparison
Jaltest, from the Spanish company Cojali, is a leading multi-brand diagnostic system for commercial and off-highway vehicles. It covers trucks, buses, trailers, light commercial vehicles, agricultural and construction machinery, and marine and stationary engines, with deep coverage of makes such as Mercedes, MAN, Scania, Volvo, DAF and Iveco as well as countless implement and engine brands. The software, paired with the Jaltest Link interface, reads and clears fault codes, shows live data, runs actuator and system tests, and performs parameter settings, calibrations, forced regenerations and component programming. Fleets, agricultural dealers and heavy-equipment workshops rely on it as a single tool across mixed fleets, with module-based licensing for CV, agricultural, off-highway and marine segments.
INSITE is Cummins' official PC service and diagnostic software for its electronic engines used in trucks, buses, off-highway, marine and power-generation applications. Connected through a Cummins INLINE datalink adapter (J1939/J1708), it reads and clears fault codes, monitors and logs live parameters, runs tests, adjusts customer-configurable parameters (road speed, idle, PTO), performs calibration updates using INCAL files, and supports maintenance and trip data review. Cummins dealers, fleets and repair shops use INSITE for troubleshooting and ECM reprogramming. It is the standard service-level tool for Cummins ECMs across on- and off-highway platforms.
Jaltest (Truck & Off-Highway Diagnostic, Cojali) and Cummins INSITE (Truck & Off-Highway Diagnostic, Cummins) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
