Possible causes

– 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 Detected Trouble Codes (DTC) have recently been cleared with a scan tool.

Tech notes

This code just means that the 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.

Symptoms

– Engine Light ON (or Service Engine Soon Warning Light)
