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.
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 OHW (Truck & Off-Highway Diagnostic, Cojali (Jaltest)) and Jaltest (Truck & Off-Highway Diagnostic, Cojali) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
