2) State Flags
| Num | Bits | Status Type |
| ETAIN | 7 6 5 4 3 2 1 0 | Information “Wide Open Throttle” (CPG) * Information “Park/Neutral” (P/N) * Information “Closed Throttle” (CPL) * Air Conditioning “Thermostat” (ACTH) Air Conditioning “Selection” (ACSEL) Information “Starter” (DEM) |
| ETAOUT | 7 6 5 4 3 2 1 0 | Check-Engine Shift Light active EGR Recirculation active Oxygen Probe Heating active Closed Loop Operation active Waste-Gate Regulation active Idle Regulation active Pump activated |
Translation Note:
“Full Gas” and “Raised Foot” made me laugh a little when it clicked for throttle modes.
Notes:
- * = Active at “0”
- The description of 1 byte PCIN is useless in the context of the “factory or after-sales” diagnosis, this byte having been added at the request of BENDIX for its end of fabrication test.
- Flags “CPG” and “CPL” could in some software types Fenix 1b or Fenix 3 become active at “1”.

| Name | Bits | Logic 1 | Logic 0 |
| DEF | 7 6 5 4 3 2 1 0 | 6 cylinders Loop Turbo 32 RPM | 4 cylinders Non Loop Atmo 25 RPM |
