Converter Carrier Frequency (9.55kHz=0,9.13kHz=1,8.71kHz=2,8.29kHz=3,7.87kHz=4,7.45kHz=5,4.8kHz=6)

“Converter Carrier Frequency (9.55kHz=0,9.13kHz=1,8.71kHz=2,8.29kHz=3,7.87kHz=4,7.45kHz=5,4.8kHz=6)” is the enhanced diagnostic signal label recorded for the linked vehicle profiles. The source does not declare a scalar display unit. The label and scope should be checked against the vehicle’s service information before interpreting a reading.

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.
