Question about 1996 Ford Taurus
The ABS hazardlight in the dashboard is always on ( int he last few weeks) , I don;t feel anything wrong with my breaks , what can i check before taking the car to repair ?
Almost nothing! ABS warning lights first require an ABS code scan to find a starting point for vehicle service. Most of the ones I scan have wheel speed sensor failures, but sometimes those failures are caused by the sensors becoming disconnected from the system. Sometimes road debris will break a sensor wire, socket or other component close to the wheel. 96 Taurus will have a sensor for each front wheel which requires sensor wiring to each wheel as well, find the sensor wire (it will be a twisted pair of wires running to the wheel hub) follow it to the hub and make sure it's connected, look at the sensor and make sure it's not damaged. Do this at each wheel. If it has 4 wheel antilock brakes, there will be a sensor at each rear wheel as well, check them all. If you decide to remove wheels, be sure to properly support the vehicle with safety stands before you get underneath the vehicle. A jack is NOT a safe support while any part of your body is in danger from being crushed by the vehicle. If you do remove wheels, do a thorough brake inspection while the wheels are off. Check the brake fluid level in the master cylinder, look for brake fluid leakage everywhere there are hydraulic lines or hoses, check the lining thicknesses of the disc brake pads and drum brake shoes. If you can't find an obvious mechanical failure, it's time for an ABS diagnostic. However if you find a visual sensor problem, and you successfully correct it, the ABS light will go off, after the system self test completes. Usually the system self test completes in 3 to 10 seconds. Here's another thing to keep in mind: The wheel speed sensors are sensitive enough to trigger the light due to a severely low tire. They also can detect a tire size mismatch so if you've replaced a tire lately pay attention to the size designations, they must match!
