Confirmed for 2021 to 2023, 2025 to 2026. In testing for 2003 to 2007, 2009 to 2010, 2017 to 2020, 2024. Not supported for 2008, 2011 to 2016.

  1. The parameter's name and its ID in the OBDb. Confirmed shows when a response from a real car confirms the parameter.
  2. The clutch mark shows a Connectable, a parameter that Pelican surfaces in its interface.
  3. The service and PID/DID asked for, the control module it's sent to, and how often Pelican asks.
  4. The reply's bytes. The parameter's bytes are blue. Bytes for other parameters in the same reply are grayed out. Hover over a byte to see the parameter it represents.
  5. Where the parameter is in the response, and how Pelican converts the raw value into a value.
  6. A real reply, decoded. The raw value comes first, then the reading.
  7. Which model years have tested this parameter.

Control module voltage VPWRSAE J1979Confirmed

Power input to the OBD control module. VPWR is normally battery voltage, less any voltage drop in the circuit between the battery and the control module.

Pelican can show this parameter as the starter battery voltage.
