Preparation For Monitor Entry
WARNING:
Strict observance of posted speed limits and attention to driving conditions are mandatory when proceeding through the following drive cycle.
- Idle the vehicle for 15 seconds. Drive at 64 km/h (40 mph) until the ECT is at least 76.7 °C (170°F).
- Is IAT above 4.4°C (40°F) and below 37.8°C (100°F)? If not, continue with the following steps but note that the EVAP Monitor Bypass portion of the drive cycle (Step 13) will be required to bypass the EVAP monitor and clear the P1000.
- Cruise at 72 to 104 km/h (45 to 65 mph) for 10 minutes.
- Bring the vehicle to a stop. Idle with the transmission in DRIVE (for automatic transmission) or NEUTRAL (for manual transmission) for two minutes.
NOTE:
This step allows engine warm-up and provides intake air temperature (IAT) input to the PCM.
NOTE:
This step executes the heated oxygen sensor (HO2S) monitor. Cruise at 64 km/h (40 mph) for 60 seconds.
NOTE:
This executes the EVAP monitor if IAT is above 4.4 °C (40°F) and below 37.8°C (100°F).
NOTE:
To initiate the monitor, TP MODE should equal PT, EVAPDC must be greater than 75%, and FLI must be between 15 and 85%.
NOTE:
Avoid sharp turns and hills.
NOTE:
This step executes the ISC portion of the Secondary Air/CCM.
