  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.

Commanded lambda

Commanded equivalence ratio EQ_RATSAE J1979Confirmed

Fuel systems that utilize conventional oxygen sensor display the inverse of the commanded open loop equivalence ratio (also known as lambda) while the fuel control system is in open loop. Will indicate 1.000 while in closed-loop fuel.

Pelican can show this parameter as the commanded lambda.

Distance since trouble codes were cleared

Distance traveled since diagnostic trouble codes cleared CLR_DISTSAE J1979Confirmed

Distance accumulated since DTCs were cleared (via an external test equipment or possibly, a battery disconnect). This parameter is not associated with any particular DTC. It is simply an indication for inspection/maintenance, of the last time an external test equipment was used to clear DTCs. If greater than 65,535 km have occurred, will remain at 65,535 km and not wrap to zero.

Pelican can show this parameter as the distance since trouble codes were cleared.

Engine coolant temperature

Engine coolant temperature ECTSAE J1979Confirmed

Your engine temperature must operate within a certain temperature range to operate efficiently and safely. If it runs too hot, then your engine could be permanently damaged. If it runs too cold, then your engine will use more fuel than necessary.

Pelican can show this parameter as the engine coolant temperature.

Engine load

Calculated engine load LOAD_PCTSAE J1979Confirmed

Represents the amount of work the engine is doing. Expected to reach 100% at wide open throttle/wide open pedal at any altitude, temperature or rpm for both naturally aspirated and boosted engines. If engine load is limited for powertrain protection e.g. engine/turbocharger protection, this value may not reach 100%. For hybrid vehicles, indicates the torque produced only by the internal combustion engine, not the torque being delivered by the entire powertrain. For electric vehicles, the meaning of this parameter is undefined.

Pelican can show this parameter as the engine load.
