Clearing DTC P1000/OBD II Drive Cycle

CLEARING DTC P1000
In some areas it may become a legal requirement to pass an inspection/maintenance (I/M) test of the OBD II system. If the vehicle powertrain system or battery has just been repaired, the OBD II system is reset to a "not ready or I/M testing" condition. To prepare the vehicle for this test and to clear Diagnostic Trouble Codes (DTC) P1000, the OBD II Drive Cycle must be performed.

OBD II Drive Cycle
The following steps must be performed 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.
Always drive the vehicle in a safe manner according to traffic conditions and obey all traffic laws.
1. Start the engine and drive the vehicle in typical city stop-and-go traffic for at least 10 minutes after it has reached normal operating temperature.
2. Idle the vehicle for at least 45 seconds, then accelerate at part throttle to near 72 km/h (45 mph).
3. Cruise and maintain a select speed in the range of 48 to 64 km/h (30 to 40 mph) on a level road with throttle held steady for at least one minute.
4. Cruise and maintain a select speed in the range of 64 to 105 km/h (40 to 65 mph) on a level road with throttle held steady for at least one minute and 20 seconds.
5. The OBD II Drive Cycle has been completed.
