1. Understanding the Ford F150 OBD2 Drive Cycle

What Exactly Is an OBD2 Drive Cycle?

An OBD2 (On-Board Diagnostics II) drive cycle is a set of predefined driving conditions that a vehicle must meet to allow its onboard computer to run and complete all of its emission system self-tests. These tests, also known as monitors, check the functionality of various components like the oxygen sensors, catalytic converter, evaporative emission system (EVAP), and more.

Why Is the OBD2 Drive Cycle Important?

Completing an OBD2 drive cycle is essential for several reasons:

• Emission Testing: Many states require vehicles to pass an emission test to ensure they are not releasing excessive pollutants into the environment. The OBD2 system plays a crucial role in this process.
• Diagnostic Purposes: The drive cycle helps to verify that all emission-related systems are functioning correctly. If a monitor fails to complete, it could indicate an underlying issue that needs attention.
• Repair Verification: After performing repairs on emission-related components, a drive cycle is necessary to confirm that the repairs were successful and the system is now functioning as intended.

Federal OBD Requirements

Federal OBD (On-Board Diagnostics) requirements mandate that all vehicles comply with evaporative emissions (EVAP) system standards. Specifically, vehicles must meet the 0.508 mm (0.020 inch) EVAP system requirements in addition to meeting the 1.016 mm (0.040 inch) EVAP system monitoring requirements. For the F-150 3.5L GTDI, the engine off 0.508 mm (0.020 inch) EVAP monitor is used rather than the 1.016 mm (0.040 inch) EVAP monitor to set I/M Readiness.

Environmental Conditions for EVAP Monitor

According to the Environmental Protection Agency (EPA), the EVAP system monitor has specific environmental conditions that must be met to run effectively. The ambient air temperature must be between 4.4 to 37.8°C (40 to 100°F), and the altitude must be below 2,438 meters (8,000 feet). If these conditions are not met, the EVAP monitor may not complete, and the OBD monitors will not be readied. In such cases, the PCM (Powertrain Control Module) must detect these conditions once (or twice on some applications) before the EVAP system monitor can be bypassed.

2. Preparing for the Ford F150 OBD2 Drive Cycle

Essential Tools and Equipment

Before starting the OBD2 drive cycle, make sure you have the following tools and equipment:

• OBD2 Scanner: An OBD2 scanner is essential for monitoring the progress of the drive cycle and reading any diagnostic trouble codes (DTCs) that may be present.
• Scan Tool Manual: Keep the scan tool manufacturer’s instruction manual handy for reference on specific functions and procedures.
• Safe Driving Environment: Choose a route with varying driving conditions, including highway driving, city streets, and stop-and-go traffic.
• Vehicle Owner’s Manual: Consult your Ford F150 owner’s manual for any specific recommendations or requirements related to the OBD2 drive cycle.

Key Preparation Steps

To ensure a smooth and successful drive cycle, follow these preparation steps:

1. Check Fuel Level: The fuel tank level should be between 1/2 and 3/4 full, with 3/4 full being the most desirable.
2. Inspect Vehicle: Ensure your vehicle is in good working condition, with no known issues that could interfere with the drive cycle.
3. Clear Diagnostic Trouble Codes (DTCs): Use the OBD2 scanner to clear any existing DTCs from the PCM. This will reset the emission monitors and allow them to run properly.

Understanding PIDs (Parameter IDs)

During the drive cycle, you’ll need to monitor specific PIDs (Parameter IDs) using the OBD2 scanner. These PIDs provide real-time data on various engine and emission system parameters. Some important PIDs to monitor include:

• AAT: Ambient Air Temperature
• ECT: Engine Coolant Temperature
• EVAPDC: Evaporative Purge Duty Cycle
• FLI: Fuel Level Input
• IAT: Intake Air Temperature
• TP MODE: Throttle Position Mode

Safety First

Warning: Strict adherence to posted speed limits and attention to driving conditions are mandatory when proceeding through the drive cycle. Failure to follow these instructions may result in personal injury.

3. Step-by-Step Ford F150 OBD2 Drive Cycle Procedure

Follow these steps to execute the Ford F150 OBD2 drive cycle. These steps are designed to complete the OBD monitors efficiently and accurately.

Step 1: Initial Setup

1. Install the scan tool.
2. Turn the ignition ON with the engine OFF.
3. Cycle the ignition OFF, then ON.
4. If needed, select the appropriate vehicle and engine qualifier on the scan tool.
5. Clear the continuous DTCs and reset the emission monitors information in the PCM. This step bypasses the engine soak timer and resets the OBD monitor status.

Step 2: Monitoring PIDs

Begin monitoring the following PIDs (if available) using the scan tool: AAT, ECT, EVAPDC, FLI, IAT, and TP MODE.

Step 3: Initial Idle and Warm-Up

1. Start the vehicle without returning the ignition to the OFF position.
2. Idle the vehicle for 15 seconds.
3. Drive at 77 to 104 km/h (48 to 65 mph) until the engine coolant temperature (ECT) is at least 76.7°C (170°F). This step prepares the vehicle for monitor entry.

Step 4: Ambient Air Temperature Check

Is the ambient air temperature between 4.4 and 37.8°C (40 and 100°F)? If AAT is not available, IAT is used. If not, complete the following steps, but note that step 16 is required to bypass the EVAP monitor and complete the OBD drive cycle. This step ensures that the engine is warmed up and provides ambient air temperature input to the PCM.

Step 5: HO2S Monitor

Cruise at 77 to 104 km/h (48 to 65 mph) for greater than 5 minutes. This step executes the HO2S (Heated Oxygen Sensor) monitor.

Step 6: EVAP Monitor

1. Cruise at 77 to 104 km/h (48 to 65 mph) for 10 minutes, avoiding sharp turns and hills.
2. Ensure the throttle is at part throttle, EVAPDC is greater than 75%, and FLI is between 15 and 85% (or between 30 and 85% for fuel tanks over 25 gallons).

This step executes the EVAP (Evaporative Emission Control System) purge flow monitor if the ambient air temperature is within the specified range.

Step 7: Catalyst Monitor

Drive in stop-and-go traffic conditions. Decelerate at closed throttle and then moderately accelerate from each stop. Include 5 different constant cruise speeds, ranging from 40 to 72 km/h (25 to 45 mph) over a 10-minute period. This step executes the catalyst monitor.

Step 8: EGR Monitor

1. From a stop, idle for 30 seconds.
2. Accelerate to 72 km/h (45 mph) at 1/2 to 3/4 throttle.
3. Cruise at steady throttle for 1 minute.
4. Repeat the idle, acceleration, and cruise sequence 3 times.

This step executes the exhaust gas recirculation (EGR) monitor.

Step 9: CCM (Engine) Monitor

Bring the vehicle to a stop. Idle with the transmission in drive (neutral for M/T) for 2 minutes. This step executes the idle air control portion of the comprehensive component monitor (CCM).

Step 10: CCM (Transmission) Monitor

• For M/T (Manual Transmission): Accelerate from 0 to 80 km/h (0 to 50 mph), and continue to step 11.

• For A/T (Automatic Transmission):

  1. From a stop and in overdrive, moderately accelerate to 80 km/h (50 mph) and cruise for greater than 15 seconds.
  2. Stop the vehicle and repeat without overdrive to 64 km/h (40 mph), cruising for greater than 30 seconds.
  3. While at 64 km/h (40 mph), activate the overdrive, accelerate to 80 km/h (50 mph), and cruise for greater than 15 seconds.
  4. Stop for at least 20 seconds and repeat step 10 five times.

This step executes the transmission portion of the CCM.

Step 11: Misfire, Fuel, and Deceleration Fuel Shut-Off Monitors

1. From a stop, accelerate to 104 km/h (65 mph).
2. Hold steady throttle for 5 seconds.
3. Decelerate at closed throttle to 64 km/h (40 mph) without using the brakes.
4. Accelerate from 64 km/h (40 mph) to 104 km/h (65 mph).
5. Hold steady throttle for 5 seconds.
6. Repeat the deceleration sequence 5 times.

This step allows learning for the misfire monitor and completion of the deceleration fuel shut-off rear HO2S monitor.

Step 12: Readiness Check

Access the On Board System Readiness (OBD monitor status) function on the scan tool. Determine whether all non-continuous monitors except the EVAP monitor have completed. If not, proceed to step 15.

Step 13: EVAP Monitor Soak Time

Turn the ignition OFF for 1 hour to allow the engine-off 0.508 mm (0.020 inch) leak check to run. This step executes the 0.508 mm (0.020 inch) EVAP monitor.

Step 14: Final Readiness Check

Turn the ignition ON. Access the On-Board System Readiness (OBDII monitor status) function on the scan tool. Determine whether all non-continuous monitors, including the EVAP monitor, have completed. If not, proceed to step 15.

Step 15: Pending Code Check and EVAP Monitor Bypass Check

1. With the scan tool, check for pending codes.
2. Conduct the normal repair procedures for any pending code concern.
3. Otherwise, repeat any incomplete monitor.
4. If the EVAP monitor is not complete and the ambient air temperature 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. Proceed to Step 16.

This step determines if a pending code is preventing the completion of the OBD drive cycle.

Step 16: EVAP Monitor Bypass

Park the vehicle for a minimum of 8 hours. Repeat steps 2 through 14, but do not repeat step 1. This allows the bypass counter to increment to 2.

4. Troubleshooting Common Issues During the Drive Cycle

Monitor Not Ready

If a monitor is not ready after completing the drive cycle, it could be due to several reasons:

• Incorrect Driving Conditions: Ensure you are following the specific driving conditions required for each monitor.
• Faulty Sensors: A malfunctioning sensor can prevent a monitor from completing. Check for any DTCs related to sensors.
• Underlying Issues: An unresolved mechanical or electrical issue can also prevent monitors from completing.

Pending Codes

Pending codes indicate that a potential problem has been detected but has not yet triggered a permanent DTC. Address any pending codes before continuing with the drive cycle.

EVAP Monitor Issues

The EVAP monitor can be particularly challenging to complete due to its specific requirements. If the EVAP monitor is not ready, consider the following:

• Temperature Range: Ensure the ambient air temperature is within the specified range (4.4 to 37.8°C or 40 to 100°F).
• Altitude: Ensure the altitude is below 2,438 meters (8,000 feet).
• Fuel Level: Maintain the fuel level between 1/2 and 3/4 full.

Tips for Success

• Steady Driving: Most OBD monitors complete more readily using a steady foot driving style during cruise or acceleration modes.
• Smooth Throttle Operation: Operating the throttle in a smooth fashion minimizes the time required for monitor completion.

6. Understanding OBD Monitor Exercised Procedures

Drive Cycle Preparation

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. Install the scan tool, turn the ignition ON with the engine OFF, cycle the ignition OFF, then ON, and if needed, select the appropriate vehicle and engine qualifier. This resets the OBD monitor status.

HO2S

To execute the HO2S monitor, cruise at 77 to 104 km/h (48 to 65 mph) for greater than 5 minutes. This test ensures the proper functioning of the heated oxygen sensors.

EVAP

To execute the EVAP purge flow monitor, cruise at 77 to 104 km/h (48 to 65 mph) for 10 minutes, avoiding sharp turns and hills. The throttle should be at part throttle, EVAPDC must be greater than 75%, and FLI must be between 15 and 85% (or between 30 and 85% for fuel tanks over 25 gallons). The ambient air temperature must be between 4.4 to 37.8°C (40 to 100°F).

Catalyst

To execute the catalyst monitor, drive in stop-and-go traffic conditions. Decelerate at closed throttle and then moderately accelerate from each stop. Include 5 different constant cruise speeds, ranging from 40 to 72 km/h (25 to 45 mph) over a 10 minute period.

EGR

To execute the exhaust gas recirculation (EGR) monitor, start from a stop, idle for 30 seconds, accelerate to 72 km/h (45 mph) at 1/2 to 3/4 throttle, and cruise at steady throttle for 1 minute. Repeat this idle, acceleration, and cruise sequence 3 times.

CCM (Engine)

To execute the idle air control portion of the comprehensive component monitor (CCM), bring the vehicle to a stop and idle with the transmission in drive (neutral for M/T) for 2 minutes.

CCM (Transmission)

• For M/T: Accelerate from 0 to 80 km/h (0 to 50 mph).
• For A/T: From a stop and in overdrive, moderately accelerate to 80 km/h (50 mph) and cruise for greater than 15 seconds. Stop the vehicle and repeat without overdrive to 64 km/h (40 mph), cruising for greater than 30 seconds. While at 64 km/h (40 mph), activate the overdrive, accelerate to 80 km/h (50 mph), and cruise for greater than 15 seconds. Stop for at least 20 seconds and repeat this sequence five times.

Misfire, Fuel And Deceleration Fuel Shut Off Rear HO2S Monitors

To allow learning for the misfire monitor and completion of the deceleration fuel shut off rear HO2S monitor, start from a stop, accelerate to 104 km/h (65 mph), hold steady throttle for 5 seconds, then decelerate at closed throttle to 64 km/h (40 mph) without using the brakes. Accelerate from 64 km/h (40 mph) to 104 km/h (65 mph), hold steady throttle for 5 seconds, and repeat the deceleration sequence 5 times.

Readiness Check

Access the On Board System Readiness (OBD monitor status) function on the scan tool to determine whether all non-continuous monitors except the EVAP monitor have completed. If not, additional steps may be required.

EVAP Engine Off

Turn the ignition OFF for 1 hour to allow the engine-off 0.508 mm (0.020 inch) leak check to run. This executes the 0.508 mm (0.020 inch) EVAP monitor.

Pending Code Check And EVAP Monitor Bypass Check

Check for pending codes with the scan tool and conduct normal repair procedures for any pending code concern. Otherwise, repeat any incomplete monitor. If the EVAP monitor is not complete and the ambient air temperature was out of the 4.4 to 37.8°C (40 to 100°F) temperature range, or the altitude is over 2438 m (8000 ft), the EVAP bypass procedure must be followed.

EVAP Monitor Bypass

Park the vehicle for a minimum of 8 hours and repeat steps 2 through 14, but do not repeat step 1. This allows the bypass counter to increment to 2.

7. OBD2 Drive Cycle Recommendations for Ford F150

Driving Style

Adopting a steady foot driving style during cruise or acceleration modes is highly recommended. Smooth operation of the throttle minimizes the time required for monitor completion.

Fuel Tank Level

Maintaining the fuel tank level between 1/2 and 3/4 full, with 3/4 full being the most desirable, helps ensure the drive cycle completes efficiently.

EVAP Purge Flow Monitor

The EVAP purge flow monitor operates only during the first 30 minutes of engine operation. When executing the procedure for this monitor, stay in part throttle mode and drive smoothly to minimize fuel slosh.

EVAP Leak Check Monitor

The EVAP 0.508 mm (0.020 inch) leak check monitor runs after the ignition is turned OFF. To complete this monitor, the vehicle must be driven to complete the EVAP purge flow monitor, which increases the temperature of the fuel in the fuel tank.

EVAP Engine Soak Times

When bypassing the EVAP engine soak times, the PCM must remain powered (ignition ON) after clearing the continuous DTCs and relearning emission diagnostic information.
