Performing Drive Cycle

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Ford RV Cutaway, 2002 Ford Pickup, 2002 Ford F550 Super Duty, 2002 Ford F450 Super Duty, and 2002 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Rough road conditions may prevent certain steady state conditions and steady accelerations from validating the transmission and load-related monitors. On models with Power Take-Off (PTO), disengage PTO system before performing drive cycle.
  1. Turn ignition on, but do not crank engine until WAIT TO START indicator turns off, or 10 seconds has passed (whichever is greater).
  2. Start engine. Allow engine to idle with transmission in Park or Neutral for 40 seconds.
  3. The following conditions must be followed to run certain OBD-II monitors that require engine to be under a load. On A/T models, select OVERDRIVE CANCEL to perform test in 3rd gear. On all models, turn on accessories (headlights, A/C compressor, blower fan, etc.). DO NOT use hazards or PTO. Select an uphill or level road. DO NOT select a downhill road. Driving downhill will unload engine and defeat test.
  4. Accelerate steadily to 3rd gear (A/T) or 4th gear (M/T) and keep engine speed at 1500 RPM for 3 seconds. Accelerate steadily from 35 MPH to 65 MPH in about 15 seconds (A/T) or 11 seconds minimum (M/T). Repeat this procedure 3 times while maintaining conditions set in step 3)  . Before proceeding, turn all accessories off and disengage OVERDRIVE CANCEL. On A/T models, go to next step. On M/T models, go to step  6.
  5. On A/T models, drive vehicle in 4th gear continuously for one minute. Accelerate steadily from a full stop to 4th gear and then return to a full stop. Repeat this procedure 10 times, then go to next step.
  6. Before continuing, use NGS tester and select EOT PID from PID/DATA MONITOR & RECORD menu. Ensure EOT PID value is more than 140°F (60°C). Allow engine to idle for 20 seconds in Park or Neutral. Turn ignition off. Start engine and allow engine to idle for 40 seconds in Park or Neutral. Repeat QUICK TEST . Drive cycle is complete.
  7. If DTC P1000 is present after performing drive cycle, repeat step  4 maintaining a minimum MFDES PID value of 37 milligrams/stroke with engine speed at more than 1500 RPM for 11 seconds. Also, maintain a minimum MFDES of 37 milligrams/stroke with engine speed at more than 2300 RPM for at least 6 seconds. Repeat step  6. MFDES PID value must remain less than 12 milligrams/stroke for 11 seconds.
