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.

Entries sharing a label and unit can use different requests or decoders. The following variants are retained separately; they are not interchangeable.
pid-edd3817c72e38278d495a30b · 1 profiles · pending-derived-external-dependency
Derived battery-cell voltage difference, labeled in millivolts. The source references two cell-voltage inputs that are absent from this exact profile; values from another vehicle profile cannot be substituted.
Original source label: [BMS] Cell voltage delta
Reference only: required signal dependencies are absent from this exact vehicle profile. Inputs from another profile are not substituted.
