Drive Cycle Procedure

NOTE: The drive cycle requires that the vehicle has been driven for 12, 070 km (7, 500 mi) or that the EGT12 temperature has been greater than 550°C (1, 022°F) for a minimum of 120 minutes for some monitors to run and complete at hot idle.
NOTE: If a diesel particulate filter (DPF) regeneration event occurs before or during the drive cycle, multiple drive cycles may be required.
NOTE: If a particular step is interrupted, simply repeat the drive mode. If the drive cycle is interrupted with an ignition OFF, only drive modes that were incomplete must be run.
NOTE: Rough road conditions may prevent certain steady state conditions and steady accelerations from validating the transmission and load related monitors.

Some monitors may require extended driving.

  1. Most OBD monitors complete more readily using a steady foot driving style during cruise or acceleration modes. Operating the throttle in a smooth transition minimizes the time required for monitor completion.
  2. The fuel tank level should be between 1/2 and 3/4 full with 3/4 full being the most desirable.

Drive Cycle Preparation
  1. Ignition ON. Do not crank until the WAIT TO START indicator cycles, or at least 10 seconds, whichever occurs first.
  2. Install the scan tool. Clear the continuous DTCs in the PCM.
 Bypasses the engine soak timer. Resets the OBD monitor status.
 
  1. Start the engine. Idle in PARK or NEUTRAL for 40 seconds.
  
Prep For Monitor Entry
NOTE: Make sure the ambient air temperature is greater than 0°C (32°F) or the monitor may not complete.
4. Drive the vehicle between 72 to 104 km/h (45 to 65 mph) until the engine oil temperature exceeds 70°C (158°F) and the exhaust gas temperature exceeds 160°C (320°F).		 Engine warm-up and provides intake air temperature input to the PCM.
  5. Monitor the following PIDs: AAT, ECT1, EGT11, EGT12, EGT13, EGT14, EOT, FLI, IAT11 and RPM.  
EGR
NOTE: Make sure the ambient air temperature is greater than 0°C (32°F) and engine coolant temperature is equal to or greater than 90°C (194°F) or the monitor may not complete.
6. From a stop, accelerate from 0 to 97 km/h (0 to 60 mph) for a minimum of 30 seconds in duration. Repeat this step 5 times.		 Executes the exhaust gas recirculation (EGR) monitor.
Fuel System Monitor 7. Accelerate from 48 to 97 km/h (30 to 60 mph) for a minimum of 20 seconds in duration. Carry out a closed pedal deceleration without applying the brake until the vehicle speed drops to 48 km/h (30 mph). Repeat this step 5 times. Executes the fuel system monitor.
  8. Drive the vehicle with a steady pedal between 89 to 97 km/h (55 to 60 mph) for a minimum of 30 minutes.  
Exhaust Gas Sensor
NOTE: If the vehicle has been driven less than 12, 070 km (7, 500 mi), this monitor will not complete until the EGT12 temperature has exceeded 550°C (1, 022°F) for a minimum of 120 minutes.
Make sure there is no accelerator pedal position (APP) or break pedal input during deceleration.9. Accelerate steadily to greater than 80 km/h (50 mph). Carry out a closed pedal deceleration without applying the brake for 10 seconds. Repeat the accelerate and closed pedal deceleration 10 times.		 Executes the exhaust gas sensor monitor.
  10. Drive the vehicle with a steady pedal between 89 to 97 km/h (55 to 60 mph) for a minimum of 10 seconds.  
  11. Bring the vehicle to a stop. Idle with the transmission in drive (neutral for M/T) for a minimum of 1 minute.  
NOx Catalyst
NOTE: Make sure the ambient air temperature is greater than 4°C (40°F) or the monitor may not complete.
12. Monitor the EGT11, EGT12, EGT13 and EGT14 PIDs. Make sure the exhaust gas temperature is between 200 to 300°C (392 to 572°F). Drive the vehicle with a steady pedal between 89 to 97 km/h (55 to 60 mph) for a minimum of 30 minutes.		 Executes the NOx catalyst monitor.
HC Catalyst
NOTE: Make sure the ambient air temperature is greater than -7°C (19.4°F) or the monitor may not complete.
For Vehicles With a GVW Under 10K,13. Drive the vehicle between 72 to 113 km/h (45 to 70 mph) untilthe engine coolant temperature exceeds 70°C (158°F) and the exhaust gas temperature exceeds 200°C (392°F). Drive the vehicle with a steady pedal between 72 to 113 km/h (45 to 70 mph) until the monitor completes or for 402.34 km (250 miles).For Vehicles With a GVW Over 10K,13. Drive the vehicle between 72 to 113 km/h (45 to 70 mph) until the engine coolant temperature exceeds 70°C (158°F) and the exhaust gas temperature exceeds 200°C (392°F). Drive the vehicle with a steady pedal between 72 to 113 km/h (45 to 70 mph) and carry out a manual regeneration event. Repeat the regeneration event if it does not complete normally.		 Executes the HC catalyst monitor.
Particulate Matter (PM) Filter 14. Drive the vehicle between 72 to 113 km/h (45 to 70 mph) until the engine coolant temperature exceeds 70°C (158°F) and the exhaust gas temperature exceeds 200°C (392°F). Executes the PM filter monitor.
  15. Drive the vehicle with a steady pedal between 72 to 113 km/h (45 to 70 mph) and carry out a manual regeneration event. Repeat the regeneration event if it does not complete normally.  
 
  1. Drive the vehicle until the monitor completes or for 3 hours after the regeneration event completes normally.
