• Engine speed is between 1,250-2,500 RPM to enable the catalyst diagnostic. Once the engine speed is in range, the engine speed must be between 1,100-2,450 RPM to keep the test enabled.
• Accelerator pedal position is at most 100%.
• Ethanol estimation is not active.
• Evaporative emission (EVAP) purge is not active.
• Post HO2S heater is On for greater than 180s.
• Mass air flow (MAF) is between 2-12g/s.
• System voltage is between 10-32V.
• Vehicle speed is between 67-120 km/h (42-75 MPH) to enable the catalyst diagnostic. To keep the test enabled the vehicle speed is between 60-120 Km/h (37-75 MPH).
• Catalyst calculated temperature is between 600-900°C (1,112-1,652°F).
• Engine is operating in closed loop.
• Engine is operating in DFCO.

This diagnostic attempts one test during each valid off-idle period once the above conditions have been met. This diagnostic attempts up to 3 tests during each drive cycle.
