Readiness Flags

Readiness Flags
The Readiness Flags provide status of required emissions system monitoring. The systems available for readiness flag status are:
- Misfiring Stage A (A Catalyst Damaging Misfire)
- Misfiring Stage B1 (Sum of the Emission Increasing Misfires in the first 1000 Revs)
- Misfiring Stage B4 (Sum of the Emission Increasing Misfires 1000 Revs)
- Evap 1
- Evap 2
- Evap 3
- Evap 4
- Catalytic converter
- Oxygen Sensor Control
- Oxygen Sensor 1 (Pre-Cat)
- Oxygen Sensor 2 (Post-Cat)
- Complete System

Test Results are indicated by Test Completed or Not Completed.

A "Readiness Code" must be stored after any clearing of fault memory or disconnection of the EMS2000. A readiness code of "0" will be stored (see below) after a complete diagnostic check of all components/systems, that can turn on the "Malfunction Indicator Light" is performed.

The readiness code was established to prevent anyone with an emissions related fault and a "Malfunction Indicator Light" on from disconnecting the battery or clearing the fault memory to manipulate the results of the emissions test procedure (IM 240).

The complete readiness code is equal to "one" byte (eight bits). Every bit represents one complete test and is displayed by the scan tool, as required by CARB/EPA.

1 = EGR Monitoring (=0, N/A with MINI)
0 = Oxygen Sensor Heater Monitoring
1 = Oxygen Sensor Monitoring
1 = Air Conditioning (=0, N/A with MINI)
0 = Secondary Air Delivery Monitoring (N/A with MINI)
1 = Evaporative System Monitoring
1= Catalyst Heating (=0, N/A with MINI at this time)
0 = Catalyst Efficiency Monitoring

Drive the car in such a manner that all tests listed above can be completed (refer to the FTP cycle). When the complete "readiness code" equals "0" then all tests have been completed and the system has established its "readiness".
