Drive Cycle Recommendations

WARNING: STRICT OBSERVANCE OF POSTED SPEED LIMITS AND ATTENTION TO DRIVING CONDITIONS ARE MANDATORY WHEN PROCEEDING THROUGH THE FOLLOWING DRIVE CYCLES. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY.

  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.
  1. The fuel tank level should be between 1/2 and 3/4 full with 3/4 full being the most desirable.
  1. 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.
  1. When bypassing the EVAP engine soak times, the PCM must remain powered (key ON) after clearing the continuous diagnostic trouble codes (DTCs) and relearning emission diagnostic information.

For best results, follow each of the following steps as accurately as possible:

OBD Monitor ExercisedDrive Cycle ProcedurePurpose of Drive Cycle Procedure

Drive Cycle Preparation

Note: To bypass the EVAP soak timer (normally 6 hours), the PCM must remain powered after clearing the continuous diagnostic trouble codes (DTCs) and resetting the emission monitors information in the powertrain control module (PCM).

1. Install the diagnostic tool. Turn the key on with the engine off. Cycle the key off, then on. Select the appropriate vehicle and engine qualifier. Clear the continuous diagnostic trouble codes (DTCs) and reset the emission monitors information in the powertrain control module (PCM)Bypass the engine soak timer. Resets the OBD Monitor status.

2. Begin to monitor the following PIDs: ECT, EVAPDC, FLI (if available) and TP MODE. Start the vehicle without returning to key off.

3. Idle the vehicle for*****at 64 km/h (40 mph) until the ECT is at least 76.7°C (170°F).

Prep for Monitor Entry4. Is the 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.

HEGO5. Cruise at 64 km/h (40 mph) for at least 5 minutes.Executes the HO2S monitor.

EVAP6. Cruise at 64 to 89 km/h (40 to 55 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%, and for fuel tanks over 25 gallons FLI must be between 30 and 85%.Executes the EVAP monitor if the IAT is within 4.4 to 37.8°C (40 to 100°F).

Catalyst7. Drive in stop-and-go traffic conditions. Include five different constant cruise speeds, ranging from 32 to 89 km/h (20 to 55 mph) over a 10 minute period.Executes the catalyst monitor.

EGR8. 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 the 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 81 km/h (0 to 50 mph), and continue to step 11. For A/T, from a stop and in overdrive, moderately accelerate to 81 km/h (50 mph) and cruise for at least 15 seconds. Stop the 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 the overdrive, accelerate to 81 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 and Fuel Monitors11. From a stop, accelerate to 97 km/h (60 mph). Decelerate at closed throttle to 64 km/h (40 mph) (no brakes). Repeat this 3 times.Allows learning for the misfire monitor.

Readiness Check12. Access the On-Board System Readiness (OBD monitor status) function on the diagnostic 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 Check13. With the diagnostic tool, check for pending codes. Conduct the normal repair procedures for any pending code concern. Otherwise, rerun any incomplete monitor. If the EVAP monitor is not complete and the 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. Go to Step 14.Determines if a pending code is preventing the clearing of P1000.

EVAP Monitor Bypass14. Park the 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.

It wont complete drive cycle if the check engine light is on or codes are stored for a different concern
