Drive cycle monitors clear after driving the vehicle in city and highway conditions for a set period of time. Every manufacturer has a way of performing the drive cycle. Which can be impossible to perform on regular streets and highways so suggest to drive the vehicle on city and highway but be steady on your throttle and braking. Dont perform wide open throttles. It might be easier to invest in a pocket scan tool that can read your monitors to see if the monitors are clearing. If monitors still wont clear then try to find a reputable shop to find out what is preventing the monitors to clear.
