Tool comparison
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.
Cat ET (Caterpillar Electronic Technician) is Caterpillar's official service software for its electronically controlled engines and machines. Connected through a Cat Communication Adapter (III), it reads and clears diagnostic and event codes, displays and logs live parameters, runs diagnostic tests and calibrations, adjusts configurable parameters, performs flash programming of Cat ECMs (with WinFlash), and reviews service and trip data. Cat dealers, fleets and equipment shops use ET across on-highway trucks, construction, mining, marine and power systems. It is the standard tool for Caterpillar engine and machine diagnostics and reprogramming where genuine OEM access is required.
Jaltest AGV (Truck & Off-Highway Diagnostic, Cojali (Jaltest)) and Caterpillar ET (Truck & Off-Highway Diagnostic, Caterpillar) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
