Drive cycles follow a general pattern, but the specific drive cycle for each monitor type and manufacturer requires slightly different driving conditions. A drive cycle includes a cold engine key-on startup followed by a warm-up period at idle. The next phase is a moderate acceleration, cruise, followed by deceleration. A second idle period for one minute with another heavier acceleration is followed by a steady-state cruise and a final deceleration. Using a scan tool, you can access the Readiness Status menu to determine which monitors have run and which have not. Driving the vehicle while displaying the Readiness Status allows the driver to view the information as each monitor is run to completion.
