  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.

Battery

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.

Control

Absolute throttle position TPSAE J1979Confirmed

Throttle position at idle will usually be more than 0%, and throttle position at wide open throttle will usually be less than 100%.

Pelican can show this parameter as the throttle position.

DTCs

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.

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.

Commanded equivalence ratio EQ_RATSAE J1979Confirmed

Commanded fuel/air equivalence ratio (lambda): actual A/F ratio over stoichiometric A/F ratio, so above 1 is lean and below 1 is rich. Multiply by the fuel's stoichiometric A/F ratio for the commanded A/F ratio (gasoline: 14.64 x 0.95 = 13.9). Systems with conventional oxygen sensors show the commanded value in open loop and 1.000 in closed loop; systems with wide-range (linear) sensors show it in both. On engines whose banks are controlled independently, this is bank 1.

Pelican can show this parameter as the commanded lambda.
