Confirmed for 2021, 2025. In testing for 1988 to 2003, 2005 to 2007, 2009 to 2010, 2014, 2016, 2019 to 2020, 2022 to 2024, 2026. Not supported for 2004, 2008, 2011 to 2013, 2015, 2017 to 2018.

  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.
