Drive Cycles

WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. 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 or death.

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 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.
When bypassing the EVAP engine soak timer, the PCM must remain powered (key 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:

OBD Monitor Exercised	Drive Cycle Procedure	Purpose of Drive Cycle Procedure
Drive Cycle Preparation	1. Install the scan tool. Turn the key ON with the engine OFF. Cycle key 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, EVAPDC, FLI and TP MODE. Start the vehicle WITHOUT returning to key OFF.
	3. Idle the vehicle for 15 seconds. Drive at 64 km/h (40 mph) until the ECT is at least 76°C (170°F).
Prep for Monitor Entry	4. Is IAT within 4° to 37°C (40° to 100°F)? If not, complete the following steps, but note that step 13 is required to bypass the EVAP monitor and clear the P1000.	Engine warm-up and provide IAT input to the PCM.
HO2S	5. Cruise at 64 km/h (40 mph) for at least 5 minutes.	Executes the HO2S monitor.
EVAP	6. Cruise at 64 to 89 km/h (40 to 55 mph) for 10 minutes (avoid sharp turns and hills). NOTE: To initiate the monitor the throttle should be at part throttle, EVAPDC must be greater than 75%, and FLI must be between 15% and 85%.	Executes the EVAP monitor if the IAT is within 4° to 40°C (40° to 100°F).
Catalyst	7. Drive in stop-and-go traffic conditions. Include 5 different constant cruise speeds, ranging from 32 to 112 km/h (20 to 70 mph) over a 10 minute period.	Executes the catalyst monitor.
EGR	8. From a stop, accelerate to 72 km/h (45 mph) at 1/2 to 3/4 throttle. Repeat 3 times.	Executes the EGR monitor.
CCM (Engine)	9. Bring the vehicle to a stop. Idle with the gear selector in DRIVE position for 2 minutes.	Executes the idle air control portion of the CCM.
Misfire & Fuel Monitors	10. Profile learning is carried out after the PCM commands engine shutdown, the fuel injectors are disabled and the generator motor spins the engine. After the profile is learned, the engine shuts down. The profile learning may require up to 4 seconds. The traction battery must be within its operating limits to carry out the profile learning.	Allows learning for the misfire monitor.
Readiness Check	11. 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 13.	Determines if any monitor has not completed.
Pending Code Check and EVAP Monitor Bypass Check	12. With the scan tool, check for pending codes. Conduct normal repair procedures for any pending code concern. Otherwise, repeat any incomplete monitor. If the EVAP monitor is not complete and IAT was out of the 4° to 37 °C (40° to 100°F) temperature range in step 4, or the altitude is over 2,438 m. (8,000 ft.), the EVAP bypass procedure must be followed. Go to Step 13.	Determines if a pending code is preventing the clearing of DTC P1000.
EVAP Monitor Bypass	13. Park the vehicle for a minimum of 8 hours. Repeat steps 2 through 12. Do not repeat step 1.	Allow the bypass counter to increment to 2.
