PC-connected EPS tester
Model code: ONELite Manufacturer: Embedra
Embedra ONELite is a bench tester for electric power steering (EPS) units that works connected to a computer. It is made for diagnosing, flashing and repairing steering ECUs on the workbench, and has no built-in touchscreen and no PC-free operation. It connects to the computer over USB-C. It delivers up to 100 A to power the steering unit on the bench and has built-in K-Line, CAN, CAN-FD and FlexRay communication, so no external protocol modules are needed. With the ONESuite desktop software (Windows, macOS) it reads live data, reads and clears fault codes, flashes and programs steering ECUs, runs brand- and model-specific special functions and creates test reports. ONESuite also includes ONEAssist, an AI assistant that analyses live ECU data and suggests repair steps. The manufacturer lists 50+ vehicle brands and adds new models with software updates. The device has an OBD-II port, a main diagnostic port, a 12 V battery connector, a pass-through charging port and two expansion (development) ports. In the box: the device, battery cable, USB-C cable, main diagnostic cable and a universal pin cable. Important: the device does not work without the ONESuite software, which is licensed per year in separate plans (Basic, Pro, Pro+, Premium, Enterprise). The licence is not included in the device price and the available functions depend on the plan.

Embedra ONELite (PC companion): Source: Embedra's public vehicle catalog and special-functions list on embedra.net; Embedra publishes no real user manual (its document library holds placeholder files). Coverage is limited to electric power steering (EPS) systems, listed per model (rack, column or pump type and communication bus). Years are the span of the generations Embedra lists; some models are entered by generation only. Embedra says it supports 50+ brands but publishes no complete list, so only the models Embedra shows are entered here; CAN-FD vehicles are not listed. Check your exact vehicle before buying. A ONESuite license is required for the device to work. Entered for all listed vehicles: read and clear fault codes, live data, actuation / component test, software update / calibration and report export. Embedra's text says ONELite offers all ONE functions with a PC, but its comparison table marks Special Functions with an x, so special functions are not entered for this device until Embedra clarifies.
The manufacturer does not list these vehicles itself. They are the same vehicle as a model it does list, sold under another brand, so the device MAY also work — there is no guarantee.
