Tool comparison
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 OHW is Cojali's diagnostic platform for off-highway equipment — construction, material handling, industrial engines, stationary and specialty machinery — covering a wide range of manufacturers with one tool and interface. It reads and clears DTCs, displays live data, runs actuator activations, calibrations, parameter settings, aftertreatment regenerations and ECU configuration across engine, hydraulic, transmission and electrical systems. Plant and equipment workshops use Jaltest OHW to service mixed fleets without separate brand tools, supported by Jaltest's technical data, wiring diagrams and guided diagnostics for listed machines, making it a practical single platform for diverse off-highory equipment.
Cummins INSITE (Truck & Off-Highway Diagnostic, Cummins) and Jaltest OHW (Truck & Off-Highway Diagnostic, Cojali (Jaltest)) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
