Dacia / Enhanced diagnostic signal

Absolute time since first ignition, days

Elapsed time labeled by the source as time since first ignition, expressed in days. Calculated from an equivalent local time-counter input in this exact profile; the counter origin and rollover have not been independently verified.

Decoder availability

Derived decoder available in the signed v82 pack. Android and iOS native replay passed with synthetic inputs; actual readings require the exact vehicle profile and all input signals. Physical vehicle validation has not been performed.

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.
