Drive Cycle Recommendations
WARNING: This page is about a different variant/trim than selected.
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 OR DEATH.
- 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.
- Fuel tank level should be between 1/2 and 3/4 fill with 3/4 fill being the most desirable.
- 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.
- 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:
ON BOARD DIAGNOSTIC (OBD) DRIVE CYCLE TABLE
| OBD Monitor Exercised | Drive Cycle Procedure | Purpose of Drive Cycle Procedure |
|---|---|---|
| Drive Cycle Preparation |
|
Bypass the engine soak timer. Resets OBD Monitor status. |
| Prep for Monitor Entry | 4. Is IAT within 4° to 37°C (40° to 100°F)? If not, complete the following steps, but note that step 14 requires to bypass the EVAP monitor and clear the P1000. | Engine warm-up and provide IAT input to the PCM. |
| HO2S | 5. Cruise at 64 km/h (40 mph) for at least 5 minutes. | Executes the HO2S monitor. |
| EVAP | 6. 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 greater than 75%, and FLI must be between 15 and 85%. | Executes the EVAP monitor if the IAT is within 4° to 40°C (40° to 100°F). |
| Catalyst | 7. Drive in stop-and-go traffic conditions. Include 5 different constant cruise speeds, ranging from 32 to 112 km/h (20 to 70 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. |
| CCM (Engine) | 9. Bring the vehicle to a stop. Idle with the gear selector in DRIVE position for 2 minutes. | Executes the ISC portion of the CCM. |
| Misfire & Fuel Monitors | 10. Profile learning is carried out after the PCM commands engine shutdown, the fuel injectors are disabled and the generator motor spins the engine. After the profile is learned, the engine shuts down. The profile learning may require up to 4 seconds. The traction battery must be within its operating limits to carry out the profile learning. | Allows learning for the misfire monitor. |
| Readiness Check | 11. 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 Check | 12. With the diagnostic tool, check for pending codes. Conduct normal repair procedures for any pending code concern. Otherwise, rerun any incomplete monitor. If the EVAP monitor is not complete and IAT was not between the 4° to 37 °C (40° to 100°F) temperature range in step 4, or the altitude is over 2,438 m. (8,000 ft.), the EVAP bypass procedure must be followed. Go to Step 13. | Determines if a pending code is preventing the clearing of DTC P1000. |
| EVAP Monitor Bypass | 13. 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 2. |
