WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, 2011 Ford Fusion, 2010 Mercury Milan, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: TO PREVENT THE RISK OF HIGH-VOLTAGE SHOCK, ALWAYS FOLLOW PRECISELY ALL WARNINGS AND SERVICE INSTRUCTIONS, INCLUDING INSTRUCTIONS TO DEPOWER THE SYSTEM. THE HIGH-VOLTAGE HYBRID SYSTEM UTILIZES APPROXIMATELY 300 VOLTS DC, PROVIDED THROUGH HIGH-VOLTAGE CABLES TO ITS COMPONENTS AND MODULES. THE HIGH-VOLTAGE CABLES AND WIRING ARE IDENTIFIED BY ORANGE HARNESS TAPE OR ORANGE WIRE COVERING. ALL HIGH-VOLTAGE COMPONENTS ARE MARKED WITH HIGH-VOLTAGE WARNING LABELS WITH A HIGH-VOLTAGE SYMBOL. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.

Diagnostic trouble code (DTC) P1000 indicates that all the OBD monitors have not yet been successfully tested. In some areas, this DTC must be cleared to pass an inspection/maintenance test. The customer should be informed that the law specifies additional city and highway driving must be done to complete the check of the OBD system. This additional driving must occur before the vehicle is tested at the inspection/maintenance station. The amount of driving required varies with individual driving patterns. To complete this requirement in the shortest amount of time, refer to ON BOARD DIAGNOSTIC (OBD) DRIVE CYCLE .

It is not necessary to clear DTC P1000 from the powertrain control module (PCM) by driving the vehicle unless it is requested by the customer to pass an inspection/maintenance (I/M) test.

The only way a DTC P1000 can be removed from memory is when all the OBD monitors are successfully completed.

The PCM sets DTC P1000 under any of the following conditions:

the vehicle is new from the factory and has not yet completed an OBD drive cycle.
the battery or PCM has been disconnected.
an OBD monitor has found a concern before completion of an OBD drive cycle.
the PCM DTCs have been cleared with a scan tool as part of a repair process.
the PCM has been flashed and the vehicle has not yet completed an OBD drive cycle.
