Our cars and trucks are filled with systems that monitor all kinds of things, and they have warning lights to go with them. Some of these warning lights are just nuisances that seem to come and go, but when they arrive, you can be sure they will keep your car or truck from passing state inspection. Aside from the dreaded Check Engine Light, the ABS malfunction light seems to be the top offender. If your dash is haunted by this light, you might want to try cleaning your ABS sensors before you resort to dropping your car off at the repair shop for diagnostics. It takes very little time and effort, and could save you hundreds in service costs!
