  • Warning Light on the Dash. What Does it Mean?

    Today's cars and trucks have many lights that can come on the dash to warn the driver of a problem in a particular system. Many times when multiple lights are on, these can be related to the same problem.

    Computers "TALK" to each other. So, a problem in one system can affect one or more other systems. Sometimes this will cause a system to be dissabled and the warning light to come on, even though that system does not have a probem.

    A good example of this is that a problem in the ABS will usually cause the Traction Control to be dissabled. You may have an indicator that shows "TRAC Off". That does not neccesarily mean there is a fault in the Traction control function.
