The drive cycle for a 2001 GMC Yukon involves a series of specific driving conditions designed to ensure that the vehicle's onboard diagnostic system can complete its readiness tests. This typically includes a cold start, driving at various speeds, and idling for a specified duration. The cycle generally requires a combination of city and highway driving, with periods of acceleration and deceleration. It's essential to follow these steps to reset the check engine light or prepare for emissions testing.
