This code 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.
The cost to diagnose the P1000 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
If DTC P1000 is triggered after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles have not been cleared.
The On Board Diagnostic (OBD) monitors are performed during the OBD Drive Cycle. P1000 is stored in continuous memory if any of the OBD monitors do not carry out their full diagnostic check.
