Truck & Off-Highway Diagnostic
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 diagnoses and force-regenerates emissions systems on trucks and machinery; Softechpro covers some heavy-duty ECU firmware among its roughly 1,400 files for DPF/EGR/AdBlue/DTC-off edits, so it can complement Jaltest's live diagnostics where firmware modification is wanted and legal.
