My 2003 ford f-250 failed inspection because the readiness monitors are set to not ready.what does it take to change them to ready?

You can go to most auto parts stores AutoZone advance Auto Napa and they will read the codes but before you do that disconnect the battery cables and clear the codes that are already set so the check engine light shuts off then drive around 15 miles or so to give the computer enough time to set new codes when the check engine light comes on after the 15 miles now go for the code scan and any codes will be new and it's easier to find your problem and no old codes will be present which might've been fixed already but the keep alive memory is still storing the old codes also you will never pass inspection with the check engine light on and don't think you can pass inspection with the light off after clearing the codes there are monitors for the ecm that have to do there self check before the system is inspection ready and if they are not ready you will fail the inspection and still have to pay it can take as much as 80 miles driving or more and the gas tank should be between 1/4 & 3/4 full for the evap monitor to clear the self test in some cases it will take a few days for that monitor to clear the self test and the car will be ready for inspection the evap test is the last monitor to clear the self test and until it does you will not pass inspection you can look up the drive cycle info for the sequence to follow after all repairs are completed and a code 1000 is present telling the inspection computer that your car is system ready otherwise you will keep paying the fees and failing the test good luck this is the right info here I'm a taxi mechanic in NYC with 50+years of experience and you can count on what you are reading as the most important information you can get about this for you and anybody else who reads this thread this is 1 million percent correct and authentic good luck again Stephen

Code P1000 is nothing , just the codes were cleared or battery was disconnected ,that's all that means . Does the O/D light flash ?
P1000 - OBD (On Board Diagnostic) System Readiness Test Not Complete The OBD monitors are performed during the OBD Drive Cycle. The P1000 will be stored in continuous memory if any of the OBD monitors do not complete their full diagnostic check.

• Vehicle is new from the factory
• Battery or PCM had recently been disconnected
• An OBD monitor failure had occurred before completion of an OBD drive cycle
• PCM DTCs have recently been cleared with a scan tool
• PTO circuit is shorted to VPWR or B+ or PTO is on during testing

The Ford P1000, inspection/maintenance (I/M) readiness function is part of the PCM strategy. A battery disconnection or clearing codes using a scan tool results in the various I/M readiness bits being set to a "not-ready" condition. As each non-continuous OBD monitor completes a full diagnostic check, the I/M readiness bit associated with that monitor is set to a "ready" condition. This may take 1 or 2 drive cycles based on whether malfunctions are detected or not. The readiness bits for comprehensive component monitoring, misfire and fuel system monitoring are considered complete once all the non-continuous monitors have been evaluated. Because the EVAP system monitor requires certain ambient conditions to run, special logic can "bypass" the monitor for purpose of clearing the EVAP system I/M readiness bit due to continued presence of these extreme conditions.
Note: The P1000 does not need to be cleared from the PCM except to pass an I/M test.

Did you recently clear the trouble codes or disconnect the battery? Once all codes are cleared, the computer will not display systems 'ready' until they go through an evaluation cycle. Some of the systems require a certain number of drive cycles before they will display 'ready'. A drive cycle is usually starting the engine from a cold start (based on coolant temperature) and driving until certain conditions are met. I don't know what the requirements are for your car, but my 2003 pickup truck requires more than 10 drive cycles before it will make the O2 sensors and evaporative emissions 'ready'. Most states only require that a certain number of systems are showing 'ready' to pass emissions certification.

Jerry, disconnecting battery will do the opposite of putting vehicle in readiness state, the only way to get in ready state is by drive cycles or a technician with a good scan tool, to make the monitored items run on command, which can put them in ready state.

Alan, I f you have had battery disconnected or had some one erase codes recently, the computer has to go through what is known as a drive cycle to complete all monitors cycling, some vehicles complete cycle in 10 miles, where as some could take 100 miles or more.
My Toyota EVAP readiness state will not cycle in cold weather and takes thousands of miles before it gets to readiness state.
I think some shops can force systems to run if they have a good scan tool.

you must not clear codes or unhook battery after doing what they call a drive cycle which resets monitors to a ready state. http://www.lhforums.net/forums/showthread.php?2755-OBD-II-and-your-Next-State-Inspection

Hi Paul@ FIREFOX,
The most common cause is the engine is not upto working temp.failing this you will need to use an O.B.D 2 meter to pin point fault this will flag up a fault code it works out alot cheaper than changing parts to cure the fault hope this helps....

alot of driving. you need to drive the vehicle until all the computers turn to the ready state. if there is a problem the check engine light will come on and the monitors will not be set.

I am in Virginia but I believe you vehicle is showing a monitors not ready for Catalyst & Evap. If that is correct you need to basically drive the car a few days. The computer will remonitor itself and should be fine following that. Most drive cycles require highway driving & city driving. Make sure you turn on a/c as well. Its not how many miles you drive but what conditions you drive that sets you monitors. You could locate the drive cycle and attempt to replicate it but its usually very difficult drive exactly as the cycle asks. Good luck.

Drive it some more. Has the battery been disconnected/replaced recently? The Inspection station should be able to print you out a drive cycle to get the monitors ready also.
