Hi Scotty,
love your youtube channel and thanks for being HONEST. I took my Hyundai Genesis 2012 (3.8 L engine) for smog check in California and unfortunately it did not pass the inspection. Everything passed except "OBDII" monitor not ready!? The mechanic who installed a new "mother board" for $1400.00 the previous month instructed me to drive the car at different speeds for different length of time / keeping it idle at different length of time. Yet this is very difficult and dangerous to do in the highway since sometimes the car need to decelerate to "0" speed.
It seems to me that this could be related to the newly installed "mother board". Do you have any suggestions?
How much did you drive your car after installing a new motherboard?
