Clear The Continuous Diagnostic Trouble Codes (DTCs) And Reset The Emission Monitors Information in The Powertrain Control Module (PCM): Description

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2005 Ford RV Cutaway, 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.

The clearing of continuous DTCs allows the diagnostic tool to command the PCM to clear/reset all emission-related diagnostic information. While carrying out this operation, a DTC P1000 will be stored in the PCM until all the OBD system monitors or components have been tested to satisfy a drive cycle without any other faults occurring. For additional information about a drive cycle, refer to ON-BOARD DIAGNOSTIC (OBD) DRIVE CYCLE . Clearing DTCs from the vehicle-specific continuous memory DTC menu clears all systems, including the OBD systems. Clearing DTCs from the OBD generic menu only clears OBD features for the 6.0L diesel.

The following events occur when the continuous DTCs and emission monitors information is cleared from the PCM:

Clears the number of DTCs.
Clears the DTCs.
Clears the freeze frame data.
Resets the status of the OBD system monitors.
Sets DTC P1000 as a vehicle-specific DTC. P1000 does not appear as an OBD DTC.

Refer to the manufacturer's manual for diagnostic tool instructions.
