A 2000 Ford pickup truck uses an OBD-I computer to control and keep track of all of the mechanical and electrical functions of the vehicle. When the ABS light illuminates on the instrument panel, it means there is a malfunction with the Anti-lock Braking System that needs to be addressed immediately. Once you take it to a qualified mechanic or fix the problem yourself, you will need to reset the ABS light right away. You can do this manually at home in just a few moments.
Lift up the bonnet of the truck and find the battery. Locate the negative terminal and find the nut attached to the cable clamp. Loosen the nut in a counterclockwise direction using an open-end wrench.
Pull on the clamp carefully in an upward direction to remove the clamp from the negative terminal. Allow the battery sit for about five minutes.
Reattach the clamp to the negative battery terminal. Tighten the nut in a clockwise direction with the open-end wrench. The ABS light should turn off.
