Obd-Ii Drive Cycles Ford Explorer Sport Trac I

Introduction

The purpose of the OBD-II drive cycle is to execute the OBD-II monitors and identify any concerns with the OBD-II system. The DTC P1000 code will be erased of all OBD-II monitors have completed during the OBD-II drive cycle.

The scan tool will be used to observe the status of each OBD-II monitor at the completion of the OBD-II drive cycle. The completion status of the Exhaust Gas Recirculation (EGR), Heated Oxygen Sensor (HO2S), Evaporative emission (EVAP), secondary Air Injection (AIR) (if applicable) and catalyst efficiency monitors can be monitored during the OBD-II drive cycle by viewing the On-Board Readiness Menu on the scan tool.

Vehicle Preparation for OBD-II or Monitor Repair Verification Drive Cycle

Note. Vehicles equipped with Power Take Off (PTO) must have this system disengaged before proceeding. Verify by viewing the PTO PID for OFF status.

1. Attach a scan tool and access the ECT, FLI, IAT PIDs. Verify the IAT PID is between 50-100°F (10-38°C). Verify the FLI PID is between 15% and 85% (only available on EVAP Running Loss systems).
2. Warm the vehicle until the ECT PID reaches a minimum of 130°F (54°C).
3. Clear all DTC's with the scan tool by pressing clear with the key on engine off. P1000 will remain. Leave the key in the ON position, and start the vehicle.
4. Access the On-Board System Readiness Menu on the scan tool to view the status of the OBD-II monitors.
5. Proceed with the OBD-II Drive Cycle or selected monitor repair verification drive cycle. Once started, the engine must not be turned off.

Note. The IAT PID must be between 50-100°F (10-38°C) during the OBD-II drive cycle to enter into all the OBD-II monitors. The FLI PID must be between 15% and 85% at all times.

1. Drive in stop-and-go traffic with at least 4 idle periods (30 seconds each) while observing the status of the OBD-II monitor on the scan tool. If the Exhaust Gas Recirculation (EGR), Heated Oxygen Sensor (HO2S), Evaporative (EVAP) emission, secondary Air (AIR) (if applicable) or catalyst efficiency monitor have not completed, drive on the highway at a constant speed over 40 mph not to exceed 65 mph for up to 15 minutes. Heavy accelerations, sudden decelerations and wide open throttles are not recommended. If the scan tool sends out a three pulse beep at any time, the OBD-II drive cycle has completed. NOTE: Vehicles equipped with the EVAP purge flow system or EVAP vapor management flow system monitor do not require EVAP monitor completion to clear the DTC P1000. If the EGR, HO2S, EVAP, secondary AIR (if applicable) or catalyst efficiency monitor has not completed, perform the corresponding monitor verification drive cycle. See «MONITOR REPAIR VERIFICATION DRIVE CYCLES»(/ford/explorer-sport-trac/i-2000-2005/remont/drive-cycles/#obd-ii-drive-cycles__monitor-repair-verification-drive-cycles) .

OBD-II Drive Cycle Test Procedure

The primary function of OBD-II Drive Cycle is to clear DTC P1000. OBD-II Drive Cycle assists in identifying an OBD-II system problem through total monitor testing. (Scheme 1) Rerunning certain parts of drive cycle will verify repair of some monitor systems.

1. For HO2S monitor repair verifications, perform steps 1) through 4) and steps 10) and 11).
2. For EGR monitor repair verification, perform Steps 1) through Step 5) and steps 10) and 11).
3. For Evaporative Emission monitor repair verification, perform Step 1) and Steps 7) through 11).
4. For Misfire Detection monitor repair verification, perform the Misfire Detection Repair Verification Drive Cycle when directed here from the Misfire Pinpoint Tests. See «Misfire Detection Repair Verification Drive Cycle»(/ford/explorer-sport-trac/i-2000-2005/remont/drive-cycles/#obd-ii-drive-cycles__misfire-detection-repair-verification-drive-cycle) .
5. For all other monitor repair verification, perform entire OBD-II Drive Cycle if directed here from the EEC-V Pinpoint Tests.

If driver is working alone, scan tool can be used after drive cycle is completed to view monitor system status. A scan tool can be installed in vehicle before drive cycle to observe DTC output. Scan tool an be used anytime through the couse of a drive cycle to observe monitor completion status by viewing On-Board Readiness Menu and PID Monitor Data Record Function.

Note. Rough road surfaces may prevent some monitors from completeing and extreme ambient temperatures may pervent the HO2S, Catalyst (both steady state and Federal Test Procedure) and Evaporative Emission monitors from initiating.

Note. If a particular drive mode of Drive Cycle is interrupted before completion, repeat drive mode. Once started, engine must not be turned off at any time during OBD-II Drive Cycle.

Note. Vehicles with PTO must have system disengaged before OBD-II Drive Cycle is started.

Note. The engine on all vehicle applications, (except, Escort/Tracer) must be warmed up to an operating temperature of at least 180,°F (82°C) before .proceeding with the OBD-II Drive Cycle (check ECT PID). The OBD-II drive cycle for the Escort/Tracer must be initiated on a cold start or at an ECT reading of less than 100°F (45°C) to assure completion of the evaporative thermister flow test (part of the comprehensive component monitor) and the catalyst monitor. This temperature can be verified with the ECT PID on the Scan Tool. Do not turn the engine off or restart anytime during the OBD-II Drive Cycle to clear DTC P1000. If a key off does occur, start the process from the beginning.

1. Start engine. Drive vehicle or idle in neutral for 4 minutes.
2. Idle vehicle in drive (neutral for M/T) for 40 seconds.
3. Accelerate vehicle to 45 MPH (M/T upshift from 1st to 5th gear, but hold in 2nd gear for at least 5 seconds) at 1/4 to 1/2 throttle for 10 seconds.
4. Drive vehicle with steady throttle at 45 MPH (M/T use 5th gear) for 30 seconds.
5. Idle vehicle in Drive (neutral for M/T) for 40 seconds.
6. Continue driving vehicle in city traffic at speeds between 25 and 40 MPH (M/T primarily drive vehicle in 3rd and 4th gear when possible) for 15 minutes. During 15 minute drive, the following modes must be achieved: At least 5 stop and idle modes at 10 seconds each. Accelerations from idle at 1/4 to 1/2 throttle. Choose 3 different speeds to do 1.5 minute steady state throttle drives.
7. Accelerate vehicle up between 45 and 60 MPH (M/T upshift to 5th gear). This should take approximately 8 minutes.
8. Drive vehicle and hold throttle steady at the selected speed between 45 and 60 MPH (M/T use 5th gear) for approximately 5 minutes.
9. Drive vehicle for 5 minutes at varying speeds between 45 and 60 MPH (M/T use 5th gear).
10. Bring the vehicle back to idle. Idle in drive (neutral for M/T) for 40 seconds.
11. Rerun quick test.T

Scheme 1

Misfire Detection Repair Verification Drive Cycle

Note. The engine must be warmed up and at an operating temperature of at least 180° F (82° C) (check ECT PID).

Note. Start the engine, drive vehicle to location where posted legal speeds between 55 and 65 MPH can be held and where sudden coast downs approaching 35 MPH can be done without interferring with normal traffic.

The purpose of this drive cycle is to verify that Misfire DTCs are not present and the Malfunction Indicator Lamp (MIL) is off. The misfire detection repair verification drive cycle is required, if there was no drive concern associated with the original complaint and DTCs are present. The misfire detection repair verification drive cycle is not required when the drive concern was classified a runs rough type and the drive concern is no longer present after the repair.

In the event that a particular drive mode of the misfire detection repair verification drive cycle is interrupted before completion, repeat this drive mode.

1. Repeat the following drive mode steps three consecutive times: Accelerate the vehicle to 60 MPH (M /T up shift to 5th gear). Drive the vehicle with a steady throttle at 60 MPH. (M /T use 5th gear) for 30 seconds Coast down vehicle with foot off of the throttle from 60 MPH to 40 MPH (M / T stay in 5th or 4th gear).
2. Bring the vehicle back to idle (idle in drive or neutral for manual transmission) for 40 seconds.
3. Rerun quick test.

Note. DTC will set when a fault is present in the system. Not all DTCs will illuminate MIL. Anytime a DTC is set or a repair is made and DTCs are cleared from PCM memory, the I/M ready monitors will reset to NO. To reset I/M monitors to a ready status, OBD-II drive cycle must be performed. Go to step 1 .

Note. PCM must see a change of at least 72°F (35°C) in ECT from the time engine is started until it reaches normal operating temperature of 158°F (70°C) before proceeding with drive modes of OBD-II drive cycle.

1. Warm engine to normal operating temperature of 158°F (70°C). Operate engine at idle for 2 minutes.
2. Accelerate at a steady rate (1/4-1/2 throttle) until vehicle reaches 55 MPH. Release accelerator pedal for at least 10 seconds. Allow vehicle speed to drop and then quickly depress accelerator to increase speed to 53-60 MPH. Drive at a steady speed of 53-60 MPH for 5 minutes.
3. Stop the vehicle.
4. Accelerate vehicle at a steady rate until speed reaches 30-35 MPH. Drive at this speed for 20 seconds, the stop vehicle. Repeat steps 3 and 4 at least 3 times.
5. Accelerate smoothly until vehicle speed reaches 50-55 MPH and drive at this speed for about 3 minutes.
6. Stop vehicle and turn engine off for at least 5 seconds.
7. Repeat steps all the previous steps at least one more time. If a step is interrupted, repeat the preceding step.

Follow the steps in order. If a step is interrupted, repeat the preceding step. Any safe driving mode is acceptable between steps.

The following procedure is designed to execute and complete the OBD-II monitors and to clear the Ford P1000, I/M readiness code. To complete a specific monitor for repair verification, follow steps 1 through 4, then continue with the step described by the appropriate monitor found under the "OBD-II Monitor Exercised" column. See Drive Cycle Procedures . When the ambient air temperature is outside 40 to 100°F (4.4 to 37.8°C), or the altitude is above 8000 feet (2438 meters), the EVAP monitor will not run. If the P1000 code must be cleared in these conditions, the PCM must detect them once (twice on some applications) before the EVAP monitor can be "bypassed" and the P1000 cleared. The EVAP "bypassing" procedure is described in the drive cycle. The OBD-II Drive Cycle will be performed using a scan tool. Consult the instruction manual for each described function.

Drive Cycle Recommendations

1. Most OBD-II monitors will complete more readily using a "steady foot" driving style during cruise or acceleration modes. Operating the throttle in a "smooth" fashion will minimize the time required for monitor completion.
2. Fuel tank level should be between 1/2 and 3/4 fill with 3/4 fill being the most desirable.
3. 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".

Vehicles equipped with Power Take-Off (PTO) must have that system disengaged before the OBD II drive cycle is initiated.

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 in appropriate SELF-DIAGNOSTICS article. 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.

The following procedure is designed to execute and complete the OBD monitors and to clear the Ford DTC P1000. To complete a specific monitor for repair verification, follow steps 1 through 4, then continue with the step described by the appropriate monitor found under the OBD monitor exercised column. When the ambient air temperature is not between 4° to 37°C (40° to 100 °F), or the altitude is above 2,438 meters (8,000 feet), the EVAP monitor does not run. If the DTC P1000 must be cleared in these conditions, the powertrain control module (PCM) must detect them once before the EVAP monitor can be bypassed and the P1000 cleared. The EVAP bypassing procedure is described in the following drive cycle.

The OBD drive cycle is carried out using a diagnostic tool. Consult the instruction manual for each described function.

1. 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.
2. Fuel tank level should be between 1/2 and 3/4 fill with 3/4 fill being the most desirable.
3. 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.
4. 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
