Drive Cycle For Readiness

I noticed today when someone posted about their readiness codes that this is not in the repair database, so I'm adding it. Basically, if you go for emissions testing and they scan your computer and find that your car is not ready although there are no diagnostic trouble codes (DTC's) or check engine light, you'll fail the inspection. A regular OBD-II scanner will also tell you that your readiness codes are not set. Volvo gives us a specific Drive Cycle that has to be done at least twice to set these codes so that you will pass inspection. In this thread, you'll find those instructions. Continue reading →
