Question about 2002 Mazda Tribute
Your ABS control module has failed. It can fail in two areas.. either the fuse controlling it which is a large fuse and located in the engine cmpartment on most vehicles or the actual ABS actuator control module which is a computer driven box located on bottom of vehicle that pumps the brakes to make them antilock (think how in the 70s you were told to pump brakes, now the car pumps its own brakes) The computer module is what burns out leaving you without ABS but not brakes themselves. Your car indicates this by showing you an ABS error light and a brake light. You are not in danger by driving the vehicle you just will NOT have antilock brakes in the event of an accident and could slide if you lock the brakes by slamming them down. Check your owners manual for the fuse location in your vehicle and inspect it. If its burned out replace it and see if this fixes the problem This is a 3-7 dollar fuse. If that doesnt do the trick unfortunately the repair is very expensive 700+ dollars for a new control unit.

It is most likely caused by one of the ABS wheel speed sensors, those little cylindrical nipples on the back of your rotors with the cable attached to them. One way to confirm it is to read out the OBD2 codes for the ABS system, but there are some checks you can do. Visually check all four cables and sensors , and make sure there is no build up on the sensors. Make sure that the connector they plug into has good connections. Look at the wheel speed sensor and make sure the gap between the sensor head and the sprocket is the same on all four wheels (should be no more than a mm). Disconnect the wheel speed sensor cable and use an ohm-meter to check the resistance of all four sensors (they should all be similar, but don't remember the value exactly). There is a way to just disable the ABS by pulling out the 60A fuse, but if you do that you may have to plug in a code reader and use a grounding jumper on the ABS electical access box (don't remember which pin) to reset the ABS faults, otherwise you won't be able to drive around like that because your engine rpm at high speeds will behave erratically. Also, do not drive around without fixing this problem or bypassing ABS completely because it could get you into an accident. My ABS problem was intermittent, and the ABS would sometimes kick in on completely dry pavement as soon as I touched the break pedal, it almost caused me to rear-end a car on couple of occasions.

This is most likely caused by an erratic wheel speed sensor when the car is turned on it does a abs system check. When the light goes on and off it is because probblem only shows up when wheel speed sensor signal is vaulty. Since you just did the front brakes and know the problem started, it is most likely that the sensor got damaged or misaadjusted. The other thing you need to check is, the sensor is magnetic and can catch alot of debris, like metal shavings from a freshly turned rotor or other metal particles. I would see if there clean and the reluctors are clean to, also check connection and wire make sure it was not damaged. The other thing that can happen but is least likely is that, materials can be pushed into the hydraulic control module. This happens by forcing the piston to the very bottom without opening the bleeder valve since, this is where dirt and corrosion usually accumulates.

You do not steam clean any engines from
1985 on, or you will have problems with water
intruding electical connectors & more
Brake fluid won't be low
As the pads wear & caliper piston moves out,
fluid level goes down,not an issue
The ABS light you should already know is a Vehicle
System Malfunction & we have had those or similar
lights on the dash of all vehilces for 30 years
So nothing new at all. Check for codes,diagnose &
have the ABS Braking System repaired

Testimonial: "I added brake fluid and the light went back out. It had also just turned over to 100k so it could also just be an automatic thing. No more trouble!"
