Missing codes in cars computer

Have a California Gold Shield Station look at your incomplete monitors and then have them check what is called the mode 6 data. That will tell you why and what monitor is not completing. If the Station does not really know how to do this, then try another Gold Shield that does know. I deal with this everyday as I am a Gold Shield Smog Technician and incomplete Monitors do do occur and it is because some component is worn to the point of almost setting a code but not quite. Or you may have a small EVAP System leak etc.

Agreed with Dan 100%; I will add, though, that Hyundai's are notorious for being extremely difficult to set monitors. The car is looking for a string of criteria to be met, and it just doesn't come easy.
