I changed my Hyundai 2000 Accent battery and My CAT and EVAP monitors will not complete. I have tried a generic drive cycle and monitors will not complete. Any suggestions.

  • How full is the gas tank? 50% full should be best. What is the ambient temperature of where you are? If it's too cold (below freezing) the monitors may not run.
