CheckEngineLightOn

Malfunction indicator lamp MILSAE J1979Confirmed

The MIL status is OFF during key-on, engine-off bulb check unless MIL has also been commanded ON for a detected malfunction. The status reflects whether there are confirmed DTC(s) stored that are illuminating the MIL. It should not reflect the status of the MIL, which could be on for a function check, flashing I/M readiness or flashing for misfire.

Pelican can show this parameter as the checkEngineLightOn.

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

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.
