Enhanced or private PID means a manufacturer-specific signal reference. It does not mean a paid PID. Request commands and decoding formulas are not needed to read this explanation and are not published here.

Which vehicle profiles list this signal?

2 connection profiles list this signal concept. Check the definition variants below for the exact profile relationships; matching display names do not make request or decoder variants interchangeable.

How should I interpret a value?

Use the exact vehicle profile and confirm the returned module and unit. An unavailable response is not zero. This reference does not supply a universal normal range or infer a failed component.
