Thanks for holding!

When a repair is made and the trouble codes are cleared, this resets the on-board computer's "Readiness Monitors". The computer now needs to do a "reboot" of sorts and re-check all the systems. The only way to cure this is to drive the vehicle. This is known as a "Drive Cycle". GM has issued a procedure that should better help get these monitors set more quickly. I can provide that drive cycle for you here: https://goo.gl/83KFfo

For best and quickest results, try to stay as close to the times and speeds stated in the procedure.
