Drive Cycle Recommendations

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: STRICT OBSERVANCE OF POSTED SPEED LIMITS AND ATTENTION TO DRIVING CONDITIONS ARE MANDATORY WHEN PROCEEDING THROUGH THE FOLLOWING DRIVE CYCLES. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY.

Most OBD monitors complete more readily using a steady foot driving style during cruise or acceleration modes. Operating the throttle in a smooth fashion minimizes the time required for monitor completion.
Fuel tank level should be between 1/2 and 3/4 full with 3/4 full 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.
When bypassing the EVAP engine soak timer, the PCM must remain powered (ignition in ON position) after the clearing the continuous DTCs and relearning emission diagnostic information.

For best result, follow each of the following steps as accurately as possible:

DRIVE CYCLE PROCEDURE CHART

OBD Monitor Exercised	Drive Cycle Procedure	Purpose of Drive Cycle Procedure
Drive Cycle Preparation	NOTE: To bypass the EVAP soak timer (normally 6 hours), the PCM must remain powered after clearing the continuous DTCs and resetting the emission monitors information in the PCM. 1. Install the scan tool. Turn the ignition ON with the engine OFF. Cycle ignition OFF, then ON. Select appropriate vehicle and engine qualifier. Clear the continuous diagnostic trouble codes (DTCs) and reset the emission monitors information in the powertrain control module (PCM).	Bypass the engine soak timer. Resets OBD Monitor status.
	2. Begin to monitor the following PIDs (if available): ECT, IAT, FLI and TP MODE. Start the vehicle without returning the ignition to the OFF position. 3. Drive at 72-104 km/h (45-65 mph) until the engine coolant temperature (ECT) is at least 60°C (140°F).
Prep for Monitor Entry	4. Is the intake air temperature (IAT) between 4.4 to 37.8°C (40 to 100°F)? If not, complete the following steps, but note that step 12 is required to bypass the EVAP monitor and clear DTC P1000.	Engine warm-up and provides IAT input to the PCM.
HEGO, CAT	5. Cruise at 72-104 km/h (45-65 mph) for at least 5 minutes.	Executes the HEGO and CAT monitor.
EVAP	6. Cruise at 72-104 km/h (45-65 mph) for 10 minutes (avoid sharp turns and hills). NOTE: To initiate the monitor, the throttle should be at part throttle, and FLI must be between 15 and 85%.	Executes the EVAP monitor if the IAT is between 4.4 to 37.8°C (40 to 100°F).
Rear HEGO	7. Cruise at 96-112 km/h (60-70 mph), release the accelerator and allow vehicle to coast to 64.4 km/h (40 mph). Repeat deceleration 6 times.
EGR	8. Drive in stop and go traffic conditions. Include 5 different constant cruise speeds, ranging from 40 to 72 km/h (25 to 45 mph) over a 10 minute period.	Executes the EGR monitor. The misfire, VCT and Fuel monitors should have completed at this point in the drive cycle.
CCM (Engine)	9. Bring the vehicle to a stop. Tap the accelerator to start the engine before shifting to NEUTRAL. Idle with the gear selector in NEUTRAL position for 3 minutes.	Executes the ISC portion of the CCM.
Readiness Check	10. Access the on-board system readiness (OBD monitor status) function on the scan tool. Determine whether all non-continuous monitors have completed. If not, go to step 11.	Determines if any monitor has not completed.
Pending Code Check and EVAP Monitor Bypass Check	11. With the scan tool, check for pending codes. Conduct the normal repair procedures for any pending code concern. Otherwise, repeat any incomplete monitor. If the EVAP monitor is not complete and the IAT was out of the 4.4 to 37.8°C (40 to 100°F) temperature range in step 4, or the altitude is over 2438 m (8000 ft.), the EVAP bypass procedure must be followed. Go to Step 12.	Determines if a pending code is preventing the clearing of DTC P1000.
EVAP Monitor Bypass	12. Park the vehicle for a minimum of 8 hours. Repeat steps 2 through 11. Do not repeat step 1.	Allow the bypass counter to increment to 2.
