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.
Jaltest AGV is Cojali's diagnostic solution for agricultural vehicles — tractors, harvesters, sprayers, telehandlers and implements — spanning many manufacturers through a single Jaltest interface and software. It reads and clears DTCs, shows live data, and performs component activations, calibrations, parameter settings, aftertreatment (DPF/SCR) regenerations, hitch/hydraulic and transmission functions, and ECU configuration. Agricultural dealers and independent workshops use Jaltest AGV to cover mixed brands without multiple OEM tools, aided by Jaltest's technical documentation and guided diagnostics for supported models, which is valuable for seasonal fleets running varied equipment.
Jaltest (Truck & Off-Highway Diagnostic, Cojali) and Jaltest AGV (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.
