Tool comparison
Jaltest CV/MCV is Cojali's multi-brand diagnostic platform for commercial vehicles — trucks, buses, trailers and light commercials — covering a very broad list of manufacturers from a single tool. With the Jaltest interface it reads and clears DTCs, shows live data, performs component activations, parameter settings, calibrations, service resets and forced DPF/SCR regenerations, and handles system configuration across engine, aftertreatment, ABS/EBS, transmission and body electronics. Independent truck and fleet workshops use it as an alternative to multiple OEM dealer tools, backed by Jaltest technical information, wiring diagrams and guided diagnostics for listed vehicles.
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 MCV (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.
