Tool comparison
TEXA Off-Highway is TEXA's multi-brand diagnostic solution for construction equipment, agricultural machinery, industrial and stationary engines and other off-highway vehicles, using IDC5 OHW software with a TEXA Navigator interface. It reads and clears DTCs, displays live data, runs component activations, and performs adjustments, resets and ECU configuration across engines, transmissions, hydraulics and body systems from many manufacturers. Fleet workshops and independent repairers use it to service mixed equipment fleets without brand-specific dealer tools. Coverage includes common off-highway engine platforms and their aftertreatment systems, with guided diagnostics and technical data for supported machines.
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.
