History
Every signal the adapter has returned
| PID | Signal | ECU | Value | Unit | Samples | Updated | Status | Raw reply |
|---|
One row per ECU and signal: two modules can both announce the same PID, and their values are kept apart. Grey rows are standard signals this vehicle did not announce. A sensor that reports "not used" is shown as text, never as a number. Derived values are computed here, not read from the car. The raw reply bytes are the evidence behind each number.
Fault codes
Read-only by design: this tool can read codes but has no way to clear them or to send anything else that writes to the car. No code reported does not mean the vehicle is fault-free: only the modules that answered were asked, and manufacturer-specific modules (gearbox internals, brakes, airbags) are outside what this tool reads.
Readiness monitors
Monitor test results (Mode 06, raw)
Off by default. Enable it in Options, then press the button above. The words are shown raw: no unit, scaling or pass/fail judgement is applied.

What this vehicle announced
Vehicle profiles (kept in this browser)
A profile remembers which ECUs and PIDs a vehicle announced, so the next scan can show what changed. It is a hint only: every scan reads the ECUs' own support pages again, and the current scan always decides. Exports carry the masked VIN only.
Manufacturer-specific data
This page only requests standard OBD-II services (01, 02, 03, 07, 09 and, if you enable it, 06) and only for items the vehicle's own modules announced. Manufacturer-specific (enhanced) requests are never sent from here, and nothing on this page clears codes, writes settings or talks to a module in a way that changes it.
Vehicle health report
Built in this browser from the data recorded in this page (a live session, the demo, or a loaded capture). Nothing is uploaded. The report separates reported fault statuses, possible concerns, what the data cannot settle, and data-quality notes about the link. It is not a repair diagnosis, and it carries the masked VIN only.
