ABS Light is On

Anonymous Asked:
Question: The "ABS" light just came on in our 1999 Volkswagen Jetta. I checked the brake fluid level, and it was full. The brakes don't seem soft, what do you think could be causing the light to be on?

Leon (Transmission Exchange) Replied:
Each wheel has a sensor that tell the computer what that wheel is doing. The sensor is connected with wire to the computer. In this kind of weather with the snow and the slush it can get to that wire and sensor. Sometimes the the snow can break a weak wire or if the insulation comes off the wire and the snow can short the signal to ground it will set the ABS light. The system is such that even if the ABS systems fails the brakes still will work, only you won't have the added protection that the ABS gives.

This is a fantastic idea for a blog. I will spread the word.

First Question: How often do tires need to changed? What is the standard for general drivers and cars? I drive a Honda. I never know if they guys at the shop are telling me the truth when it comes to my tires.

When you say change your tires I assume that you are meaning to rotate them. You should change your motor oil every three thousand miles, so using that as your reminder every other oil change would be six thousand miles. If you rotated them at that interval it would get the maximum wear out of your tires. In Utah if your tires are worn down to the wear bars near the bottom of the grooves in your tire tread they fail the safety inspection and must be replaced. There are many different grades of tires, buy ones with a good mileage rating if you are going to keep the car. It will be cheaper in the long run.
