How to read a parameter card

Commanded Fuel Rail Pressure A FRP_A_CMDConfirmed

Displays commanded fuel rail pressure when the reading is referenced to atmosphere (gage pressure)

  • Request01 6D
  • Service 01PID 6D
  • Module7E0 → 7E8
  • Every250 ms

  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.
