P1000 FORD - On Board Diagnostic System Readiness Test Not Complete
The vehicle is new from the factory.
Battery or Powertrain Control Module (PCM) had recently been disconnected.
An OBD monitor failure occurred before completion of an OBD drive cycle.
PCM Diagnostic Trouble Codes (DTC) have recently been cleared with a scan tool.
This code just means that the Powertrain Control Module (PCM) didn't complete a full diagnose cycle, and is set when the battery have been disconnected, codes have been cleared or sometimes even when the vehicle have been towed. No scanner it's necessary to clear the code, driving the vehicle for a few minutes (sometimes more) to complete the diagnose cycle will clear the code. Clearing the code will reset the light unless other codes present.
When is the code detected?
If DTC P1000 is triggered after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles have not been cleared.
Engine Light ON (or Service Engine Soon Warning Light)
