Readiness Status
Gas Engine
MENU  More ..  Readiness
Reports the readiness status for various non-continuous/drive-cycle readiness tests. The readiness status will continually be read and
displayed. As a result, if the ECM is busy running the monitors the status may change in real time. Pressing any key will halt the
readiness status monitoring and exit to the Menu. The following potential readiness test status is presented by UltraGauge:
Gasoline Engine Monitors
Catalyst Monitoring
Heated Catalyst Monitoring
Evaporative System
Secondary Air System
Air Conditioning
02 Sensors
O2 Sensors Heating
EGR/VVT
Please see the prior Readiness discussion for more details.
Note: Not all vehicles support and perform all of the tests above.
Note: For those States that use Readiness as a means to determine Emissions compliance, the required tests and the number of tests is
State dependent. Often a few failing monitors will not cause the emission inspection to fail. Check the State’s website to determine
which readiness tests are critical.
Note: To restart/clear Right Column monitor status, select:
MENU  Trouble Codes...  Clear Check Engine
This will clear any posted trouble codes and restart ECM readiness monitors
Diesel Engine
MENU  More ..  Readiness Diesel
The readiness tests performed for a Diesel vehicle are different than those for gasoline vehicles.
The readiness status will continually be
read and displayed. As a result, if the ECM is busy running the monitors the status may change in real time. Pressing any key will halt
the readiness reading and exit to the Menu.
For Diesel Vehicles, the following potential readiness test status is presented:
Diesel Monitors
NMHC Catalyst Non-Methane Hydrocarbon Converting Catalyst. This monitor ensures the proper
Conversion of Hydrocarbons and Carbon Monoxide
NOx/SCR After treatment Nitrogen Oxide / Selective Catalyst Reduction Catalyst.
This monitor ensures proper NOx conversion. A NOx sensor measures
the NOx concentration downstream of the SCR
Boost Pressure Boost Pressure Control System monitoring.
Air Conditioning For legacy R12 Systems. Not commonly supported
Exhaust Gas Sensor O2 and/or NOx Sensors.
PM Filter Particulate Matter Filter Monitor
EGR/VVT Exhaust Gas Recirculation system monitor
These monitors and the tests performed are generally manufacturer and vehicle specific. Please consult information specific to your
vehicle. Though specific to 2011 Ford Diesels, the following provides a good general guide to the monitors/tests, systems and
components of a modern Diesel vehicle:
