V500 OBD2 Engine Code Reader with Live Data & Voltage Display

Find a starting point for checks when an engine warning appears. This V500 wired OBD2 reader retrieves available engine codes and live data from compatible OBD-II vehicles. It is for owners and workshop users who want useful information before deciding on the next diagnostic step.

• ✅ Read stored codes before planning a repair — The engine-code menu retrieves available diagnostic trouble codes.
• ✅ Watch values during a controlled check — Live-data and graph screens display the vehicle's available parameters.
• ✅ Keep fault-time context with the code — Freeze-frame access retrieves an available snapshot.
• ✅ Check monitor status before further testing — The I/M readiness screen shows available emissions-monitor information.
• ✅ Work from a dedicated handheld screen — Physical buttons navigate the reader without using a phone as its main display.

Gather engine information before the next diagnostic step

Connect the attached lead to a compatible OBD-II diagnostic socket and navigate with the handheld controls. The screen provides code reading, a DTC lookup menu, live data and readiness information. The available functions depend on the vehicle protocol and data supplied; all-vehicle and all-module coverage is not established.

A trouble code identifies a reported condition, not a confirmed failed part. Compare the code with available live values, freeze-frame information and the vehicle's service procedures. The voltage view provides a supply-voltage reference rather than a complete battery-capacity test.

Record the information you need before clearing codes. Clearing does not fix the underlying fault and can reset readiness information. Choose red, orange, blue, yellow or black housing at checkout. One selected reader with its attached OBD lead is supplied; no separate battery is included, and operation uses the compatible diagnostic connection.

The V500 has a colour screen with code, live-data and readiness menus.

The voltage function provides a supply-voltage reference.

Colour options refer to the selected housing.

Physical navigation keys sit below the screen.

Graphs display parameters available from the connected vehicle.

Diagnostic availability depends on the vehicle and protocol.
