Refers to data denoting the operating condition when trouble is sensed by the on-board diagnosis system.
A list of the support data and PID (Parameter Identification) codes are shown in the following table.
| PID | Data | Unit of measure |
|---|---|---|
| 02 | DTC that caused CARB required freeze frame data storage | |
| 03 | Fuel system control status | |
| 04 | Calculated engine load value | % |
| 05 | Engine coolant temperature | °C |
| 06 | Short term fuel trim | % |
| 07 | Long term fuel trim | % |
| 0B | Intake manifold absolute pressure | KPa |
| 0C | Engine revolution | RPM |
| 0D | Vehicle speed | Km/h |
| 0E | Ignition timing advance | ° |
| 0F | Intake air temperature | °C |
| 10 | Air flow rate from mass air flow sensor | G/sec |
| 11 | Throttle valve opening angle | % |
| 15 | Oxygen sensor output voltage and short term fuel trim associated with oxygen sensor | V and % |
| 1C | Supporting OBD system |
