Tool comparison
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.
QuickServe Online (QSOL) is Cummins' official service information portal, providing engine-specific repair and troubleshooting procedures, wiring diagrams, specifications, service bulletins and parts information keyed to a Cummins engine serial number (ESN). Technicians look up the exact build, fault-code trees, torque values and part numbers for a given engine. It is a documentation and reference system rather than a diagnostic interface, used alongside INSITE for actual fault reading and reprogramming. Fleets and shops rely on QuickServe for accurate, engine-specific Cummins repair data that matches each unit's exact configuration.
Jaltest OHW (Truck & Off-Highway Diagnostic, Cojali (Jaltest)) and Cummins QuickServe (Truck & Off-Highway Diagnostic, Cummins) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
