are mandatory when proceeding through the following drive cycle.
7. NOTE: This step allows engine warm-up and provides intake air temperature (IAT) input to the
PCM.
Idle the vehicle for 15 seconds. Drive at 64 km/h (40 mph) until the ECT is at least 76.7°C (170°
F).
8. 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.
9. NOTE: This step executes the heated oxygen sensor (HO2S) monitor.
Cruise at 64 km/h (40 mph) for 60 seconds.
10. 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.
Cruise at 72 to 104 km/h (45 to 65 mph) for 10 minutes.
11. NOTE: This step executes the ISC portion of the Secondary Air/CCM.
Bring the vehicle to a stop. Idle with the transmission in DRIVE (for automatic transmission) or
NEUTRAL (for manual transmission) for two minutes.
Pending Code and EVAP Monitor Bypass Check
12. NOTE: This determines if a pending code is preventing the clearing of P1000.
NOTE: If the EVAP monitor is not complete and IAT was below 4.4°C (40°F) or above 37.8°C
(100°F) temperature range in Step 8, or the altitude is above 2,438 meters (8,000 feet), the
EVAP Monitor Bypass (Step 13) must be carried out.
Using the scan tool, check for pending codes. Conduct normal repair procedures for any
pending code concerns. Rerun any incomplete monitor.
EVAP Monitor Bypass
13. NOTE: This allows the bypass counter to increment to two.
NOTE: Do not repeat Step 4.
Park the vehicle for a minimum of eight hours. Repeat Steps 5 through 12.
