Every modern car has a computer which manages the engine and all other systems and sensors in the vehicle. This computer is called the powertrain control module. It is programmed to conduct regular diagnostic checks on various components of the emission control system, such as the transmission, engine, and fuel systems. When a diagnostic check is completed, it relays this information to a readiness monitor.
Self-diagnostic checks are always taking place when you drive your vehicle. The powertrain control module needs to make sure that all your components are functioning properly so that you can drive safely. Whenever a diagnostic check passes inspection, the readiness monitor will show “Ready” status. If there is a problem with the diagnostic check or the results were bad, then it’ll show “Not Ready” or “Incomplete.”
However, if the diagnostic checks are unable to be completed, then you should see trouble code P1000 appear on the dashboard. If your vehicle doesn’t display trouble codes on the dashboard, then you must run a diagnostic scan on the powertrain control module to discover it. If you’ve disconnected your battery or repaired your vehicle recently, then it may have cleared the previous data from the monitors. That’ll definitely cause trouble code P1000 to come up.
This is not a problem that will affect your driving at all. In fact, the only two symptoms that you might notice are a Check Engine light illuminating on your dashboard or a failed emissions test because you have incomplete emissions monitors. But you can certainly survive on the road without having your diagnostic checks working. Of course, if something truly does go wrong with your emissions system, then your powertrain control module won’t let you know unless you resolve this issue.

The simple solution is to update the software of the powertrain control module. Just bring your vehicle to the dealership and have the technicians perform the update on your module. It should not be too expensive to have this done because it mostly involves the use of software and computer gadgets. Once you get the readiness monitors back to “ready” status, you can have peace of mind knowing that your emissions control system is being monitored properly again.
