Confirmed for 2006, 2010, 2013, 2015, 2017. In testing for 1999 to 2001, 2003 to 2004, 2007, 2009, 2011 to 2012, 2014, 2016, 2018 to 2019, 2021, 2023 to 2024. Not supported for 2002, 2005, 2008, 2020, 2022, 2025 to 2026.

  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.
