    Year, make, model, and engine size?

    Is the ABS light on?

    Are there codes that lead you to believe the abs motor is bad?

The ABS motor is serviced as an assembly. Product liability being what it is these days.

What makes the ABS MOTOR turn on and off . 1996 ford explorer. My ABS MOTOR WORK IF I hot WIRE IT To BATTERY. BUT WON'T WORK normal. ALL BRAKER AN FUSES REPLASED. IT QUIT WORKING AFTER I BLOW A tire

The ABS motor is controlled by the computer. The function is different for 2 wheel vs 4 wheel ABS. My guess is that you have 2 wheel ABS. Look at the write ups by Chris and Helmet. Basically the computer will compare engine speed and transmission speed to wheel rotation during braking. If very different, it will pulse the braking system to avoid skids and most effectively apply braking pressure.

Abs motor pack

You have valves in the abs block altho the motor might be working it could the valve is not working is the load sensing vavle working on the rear axle. Check the master cylinder is pumping fluid to the pump then check if fluid is coming from the from abs pump when brake peddle is applied. Ps don't forget you might have to bleed brakes once the pipes have been slackened

I have a 1999 Sable and the ABS motors seem to come on and off randomly. I cant aford to fix the problem. Perhaps pulling the fuse and disconnecting the ABS system would be an easy solution?

yes you can do this then car will revert to conventional braking system ,but the ABS motors do run randomly to maintain pressure so its nothing to worry about perhaps motors are a bit noisey which is why you can hear them ,I would advise you to leave well alone to be honest as i think teh system is working ok abeit a bit noisey

abs stands for anti breaking system its something strting to go wrong with your brakes it throws that code until you fix the problem could be serious could be low break fluid find a honest mechanic shop most of them will tell you what it means free they can pull the abs code that tells them what it is good luck

ABS light went on while driving and noise stays on after ignition is turned off.

There is a relay inside of the ABS motor housing that can stay engaged making the motor run continuously without the key in the run position. If this is the problem the only fix is to replace the Brake Pressure Modulator Valve assembly. You may also may need to replace the Control Module that is attached to it.

The motor can be unplugged from the module and will shut off. The ABS light will stay on until it if fixed properly. The other way to shut down the motor is to remove the ABS fuse in the underhood fuse box.

The ABS module and BPMV are expensive and the brakes will have to be bled. Junk yard parts can be cheaper if your capable to replace them.

Brake and abs lights stays on in a 2003 gmc safari wile driving after a small period of time. put new pads and there's no leaks in the calipers

Have the ABS Distribution Unit/Computer checked at the dealer.

NOTE: ABS Unit located under the vehicle, under the drivers seat. Listen to it with the vehicle running with no brake on... if you hear ABS motor running continuously, unplug ABS fuse in fuse block under hood to turn ABS motor off and be able to use vehicle in the meantime whether you decide to get the ABS fixed or not.. This will not affect brake operation, but will disable ABS feature. ABS and Brake idiot lights will remain on. No way to turn them off short of having the correct repair done. ABS Distribution Unit/Computer is very expensive part and requires expensive labour for replacement.

I know nothing about cars but my ABS just activated on my 2001 Chevy Suburban. Cut ignition off and motor still running. Happened in 2005 also, cost $1500 to fix. Is there anything I can do so I can drive...

Remove the ABS maxi-fuse (Large fuse) located in the under hood electrical center. In the event you cannot locate that fuse, you can unplug the ABS pump two wire connector at the ABS pump motor located under the vehicle.
Good luck

I have a 1997 Blazer. The ABS light comes on intermittently. When the ABS light is on the power windows and blower motor do not work. When the ABS light is off everything works just fine. Help????

That sounds strange about the power windows and the blower motor not working when the ABS light comes on. I happen to have a 99 Chevy blazer and I had the ABS light come on several times. There are ABS sensors on the two front wheel bearing hubs. If you take off the front wheels you will be able to see a black electrical cable that has 2 wires inside of it. This cable is coming directly from the ABS sensor on the wheel hub and is strapped to a bracket the is on the upper ball joint. From the hub it then goes to a plug connector that is under the protective flap that you lift to change your spark plugs. What I found that is a common problem is that wire tends to corrode or doesn't have enough slack in it when making turns and starts to pull and break. Examine that cable and if you see any breaks in it, that will cause the ABS light to come on. Also if you can get to the plug underneath the flap, unplug it and use a multimeter to see if you are getting any resistance on the two wires. If you aren't getting any resistance then your sensor is bad or you have a broken wire to the sensor. On my vehicle the ABS light kept on coming goin on and off intermitently and I found that wire from the sensor to the plug had a break in it. I stripped the wires back, spliced them together, soldered them and I used heat shrink tubing to cover the connections. The ABS light went out and it has been fine ever since. Hopefully this will solve your problem as well.

Abs motor run after ignition switch is shut off on 2000Expedition

the quickest way to check if the ABS motor is working properly, is to switch the relay with another to verify it is not just a stuck open relay! if this doesnt solve it, have a scan done on ABS system to verify component function......good luck, marty

92 Gr Caravan ABS system stop working

The most common failure of an ABS is wheel sensors. I doubt you'll have to replace the entire system.
