| 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 | kPaA |
| 0C | Engine revolution | rpm |
| 0D | Vehicle speed | MPH |
| 0E | Ignition timing advance | ° |
| 0F | Intake air temperature | °C |
| 10 | Air flow rate from mass air flow sensor | gm/s |
| 11 | Throttle valve opening angle | % |
| 15 | O2 sensor output voltage and O2 sensor short term fuel trim | V and % |
| 1C | Supporting OBD system | - |
