EVEASY / Enhanced diagnostic signal

WCBS Master cylinder pressure v1

WCBS master-cylinder pressure reference, scaled by 1/16 from the two-byte source value. The source lookup maps raw 65535 to zero; this is a defined decoding result, not proof of zero physical pressure.

Decoder availability

Android and iOS native replay passed. Vehicle support requires a positive ECU response; no physical vehicle validation is claimed.

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?

1 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.
