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 (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.
