Ford Motor Company Driving Cycle
Description of OBDII 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:
For best results, follow each of the following steps as accurately as possible:
Drive Cycle Procedure
Drive Cycle Procedure
|1. Install scan tool. Turn key on with the engine off. Cycle key off, then on. Select appropriate Vehicle & Engine qualifier. Clear all DTC's/ Perform a PCM Reset.||Bypasses engine soak timer. Resets OBDII Monitor status.|
|2. Begin to monitor the following
PIDs: ECT, EVAPDC, FLI (if available) and TP MODE.
Start vehicle WITHOUT returning to Key Off.
|3. Idle vehicle for 15 seconds. Drive at 64 Km/h (40 MPH) until ECT is at least 76.7°C (170° F).|
|Prep for Monitor Entry||4. Is IAT within 4.4 to 37.8°C (40 to 100° F)? If Not, complete the following steps but, note that step 14 will be required to "bypass " the Evap monitor and clear the P1000.||Engine warm-up and provide IAT input to the PCM.|
|HEGO||5. Cruise at 64 Km/h (40 MPH) for up to 4 minutes.||Executes the HEGO monitor.|
|EVAP||6. Cruise at 72 to 104 Km/h (45 to 65 MPH) for 10 minutes (avoid sharp turns and hills) Note, to initiate the monitor: TP MODE should =PT, EVAPDC must be >75%, and FLI must be between 15 and 85%||Executes the EVAP Monitor (If IAT is within 4.4 to 37.8° (40 to 100°F))|
|Catalyst||7. Drive in stop and go traffic conditions. Include five different constant cruise speeds, ranging from 40 to 72 Km/h (25 to 45 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.|
|SEC AIR/CCM (Engine)||9. Bring the vehicle to a stop. Idle with transmission in drive (neutral for M/T) for 2 minutes.||Executes the ISC portion of the CCM.|
|CCM (Trans)||10. For M/T, accelerate from 0 to 80 Km/h (o to 50 MPH), continue to step 11. For A/T, from a stop and in overdrive, moderately accelerate to 80 Km/h (50 MPH) and cruise for at least 15 seconds. Stop vehicle and repeat without overdrive to 64 Km/h (40 MPH) cruising for at least 30 seconds. While at 64 Km/h (40 MPH) , activate overdrive and accelerate to 80 Km/h (50 MPH) and cruise for at least 15 seconds. Stop for at least 20 seconds and repeat step 10 five times.||Executes the transmission portion of the CCM.|
|Misfire & Fuel Monitors||11. From a stop, accelerate to 104 Km/h (65 MPH). Decelerate at closed throttle until 64 Km/h (40 MPH) (no brakes). Repeat this 3 times.||Allows learning for the misfire monitor.|
|Readiness Check||12. Access the ON-Board System Readiness (OBDII 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||13. With the scan tool, check for pending codes.
Conduct normal repair procedures for any pending code concern. Otherwise, rerun any
Note: if the EVAP monitor is not complete AND 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.
Proceed to step 14.
|Determines if a pending code is preventing the clearing of P1000.|
|Evap Monitor "Bypass"||14. Park vehicle for a minimum of 8 hours. Repeat steps 2 through 12. DO NOT REPEAT STEP 1.||Allow the "bypass" counter to increment to two.|
