Ford Motor Company Driving Cycle
Description of OBDII Drive Cycle
The following procedure is designed to execute and complete the OBDII monitors and to clear the Ford P1000, I/M readiness code. To complete a specific monitor for repair verification, follow steps 1 through 4, then continue with the step described by the appropriate monitor found under the “OBDII Monitor Exercised” column. When the ambient air temperature is outside 4.4 to 37.8°C (40 to 100° F), or the altitude is above 2438 meters (8000 feet), the EVAP monitor will not run. If the P1000 code must be cleared in these conditions, the PCM must detect them once (twice on some applications) before the EVAP monitor can be “bypassed” and the P1000 cleared. The Evap “bypassing” procedure is described in the following drive cycle.
The OBDII Drive Cycle will be performed using a scan tool. Consult the instruction manual for each described function. NOTE: A detailed description of a Powertrain Control Module (PCM) Reset is found in this section, refer to the table of contents.
Drive Cycle Recommendations:
Most OBDII monitors will complete more readily using a “steady foot” driving style during cruise or acceleration modes. Operating the throttle in a “smooth” fashion will minimize the time required for monitor completion.
Fuel tank level should be between 1/2 and 3/4 fill with 3/4 fill being the most desirable.
The Evaporative Monitor can only operate during the first 30 minutes of engine operation. When executing the procedure for this monitor, stay in part throttle mode and drive in a smooth fashion to minimize “fuel slosh”.
STRICT OBSERVANCE OF POSTED SPEED LIMITS AND ATTENTION TO DRIVING CONDITIONS ARE MANDATORY WHEN PROCEEDING THROUGH THE FOLLOWING DRIVE CYCLES.
For best results, follow each of the following steps as accurately as possible:
