Clearing DTC P1000/OBD II Drive Cycle

DESCRIPTION
In some localities it may become a legal requirement to pass an Inspection/Maintenance (I/M) test of the OBD II System. If the vehicle's OBD II system or its battery has just been serviced, the PCM system is reset to a "not ready for I/M testing" condition. To prepare the vehicle for this test and to clear the DTC P 1000, the OBD II drive cycle must be performed.

OBD II DRIVE CYCLE
The following steps must be run in the order shown. If Steps 2, 3, or 4 are interrupted, repeat the step before proceeding. Any safe driving mode is acceptable between steps.
1. Start engine and drive vehicle in typical city stop-and-go traffic for at least 10 minutes after it has reached normal operating temperature.

NOTE: Always drive vehicle in a safe manner according to traffic conditions and obey all traffic laws.

2. Idle vehicle for at least 45 seconds, then accelerate at part throttle to near 72 km/h (45 mph).
3. Drive to accumulate at least 4 minutes in the range of 48-72 km/h (30 to 45 mph). If stop-and-go conditions occur, the designated accumulative time must be within the 32-72 km/h (20 to 45 mph) range. No wide-open throttle (WOT) conditions should be encountered.
4. Cruise and maintain a select speed in the range of 48-64 km/h (30 to 40 mph) on a level road with throttle held steady for at least 1 minute.
5. Decelerate and idle for at least 1 minute.
6. Accelerate to 89 km/h (55 mph) at half throttle (elapsed time is about 10 seconds).
7. Cruise and maintain select speed in the range of 64-105 km/h (40-65 mph) on a level road with throttle held steady for at least 1 minute and 20 seconds.
8. Bring vehicle down to idle.
9. While the ignition key is ON (vehicle at idle), check for continuous memory DTCs.
10. If system PASS, OBDII Drive Cycle is complete. If DTC P1000 is received, check monitor completion status (On-Board Readiness Menu), and repeat the drive cycle.
