DTC P1000: - On-Board Diagnostic (OBD) Systems Readiness Test Not Complete

DTC P1000: - ON-BOARD DIAGNOSTIC (OBD) SYSTEMS READINESS TEST NOT COMPLETE

Description:	The OBD monitors are carried out during the OBD drive cycle. This DTC is stored in continuous memory if any of the OBD monitors do not carry out their full diagnostic check.
Possible Causes:	The vehicle is new from the factory Battery or powertrain control module (PCM) had recently been disconnected An OBD monitor concern occurred before completion of an OBD drive cycle PCM DTCs have recently been cleared with a scan tool Power take off (PTO) circuit concern or PTO is on during testing.
Diagnostic Aids:	This DTC, 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 one or two drive cycles based on whether concerns are detected or not. The readiness bits for comprehensive component monitoring (CCM), 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 the purpose of clearing the EVAP and I/M readiness bit, due to continued presence of these extreme conditions. DTC P1000 does not need to be cleared from the PCM except to pass an I/M test. The malfunction indicator lamp (MIL) flashes after a period of time with the ignition in the RUN position (engine not running) if DTC P1000 is set.
