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 is the common shorthand for Caterpillar Electronic Technician, Caterpillar's dealer-level diagnostic and programming software for its electronic engines and machines. Using a Cat Communication Adapter, it retrieves active and logged fault and event codes, streams and records live data, executes diagnostic tests and sensor calibrations, sets configurable parameters, and flashes Cat ECMs via WinFlash. It spans Caterpillar on-highway, construction, mining, marine, industrial and generator applications. Technicians treat CAT ET as the essential tool for Caterpillar troubleshooting, ECM reprogramming and equipment configuration wherever OEM-level access to Cat control systems is required.
