Question about 2004 Buick Rainier

1 Answer

Run Away ABS

My ABS light came on the other night. At the same time I got this continuous humming sound under the car (just behind the front drivers side wheel) The noise continued even with the car off. After waiting 3 hours, I chose to disconnect the fuse for the ABS. This stopped the humming, but light still on, and brakes harden after a few miles. What needs to be replaced? Where is it?

    ABS system was tested, no fault codes for the system. When the fuse is in place the brakes work properly but the motor/pump runs constantly.

There is no one answer or cure all for this problem, you need to have the ABS system tested for fault codes and then the technician can give you an informed idea of what the problem might be and some idea of the cost to repair it

    Check the ABS relay, I really feel a HELPFUL rating would be the correct rating, I am not a paid employee of, just do it to try and share my years of experience with others, I don't know everything, but have a good working knowledge of all automotive systems.

Humming noise from engine when driving lexus

Your wheels each have rotor speed sensors...

These are easily bent or misaligned... and can be
put into a position of INTERFERENCE with the
(particularly ... in YOUR case "RIGHT FRONT")

These parts ARE NOT CHEAP... and WILL
ADVERSELY impact the operation of BOTH
TRACTION CONTROL & ABS (anti-lock brakes)...

It is a WORK ERROR... while your BRAKES
were being "inspected" ... your
rookie dealer "mechanic" most likely did

ROAD-HAZARDS "can" break these parts...
but reasoning with your fully functioning
brain... (OCCAM'S Razor)
Occam razor Wikipedia the free encyclopedia

You should NEVER HAVE LEFT... without
having a SERVICE PERSON making a note
of your ABS & TRC lights...

You do have rights... and government
licensing boards... In the unlikely event
your "dealer" FAILS to recognize their
obvious WORK ERROR...

OCCAMS razor:
When you hear the thunder of hoof
beats... Think HORSES... (not Zebras)

I have had many BAD experiences with
DEALERS... (& I trust my lying eyes)...

I'm just saying (in my opinion)... Get back to that
"DEALER"... pronto...!!

Abs light came on while driving and when engine is shut off makes a loud humming sound ? took the fuse out to make hummimg noise go away and now abs light and emergency parking brake are on all the time...

have the abs module checked for codes to find out what the problem is.when the system detects a fault in the system it turns on the abs light and check the e-brake to make sure its all the way off.the humming noise sounds like its coming from the abs hydraulic unit that`s not shutting off.

I ve got a kalos 1.4sx 2008 and i ve got problems with the brakes. The brakes ''crunch'' when i m bringing the car to a halt,even on dry roads. The abs warning light has been on a couple of times but...

The Chevrolet/GM autos rely on a Kelsey ABS actuator system that is electronically controlled. I know its hard to describe sounds, but is it possible the crunch is a hum? If the ABS light comes on and goes off after restart it means one of two things. That the ABS controller is going bad or the speed sensors on the wheels have come loose or gone bad. Under your hood there is a fuse compartment that contains the fuse that controls the ABS system on your vehicle. Its a 60 Amp fuse and large.. Look in your owners manual for its location. . Check it with the vehicle OFF to make sure its not blown or cracked. Leave the fuse disconnected and start the car. The ABS light should STAY on as well as the parking brake light. Test your brakes by pressing down on them while the car is in park and not moving.. do you hear the sound. If you DONT hear the sound then the ABS control module is causing the brake pump to work continuously and thus your "noise". YOu can confirm by placing the fuse back in place and then listening to the car about where the drivers door is... do you hear a hum? If so you can leave the fuse disconnected to deactivate the ABS module. The brakes will still function you just WONT have ABS capability. Confirm this with a very slow roll from park or neutral and press brakes to stop. If you dont hear the noise or a hum, reconnect the fuse and take the car for a drive. Turn to the left and right while applying the brake at an intersection.. vehicle in motion slightly. Do you notice that the ABS light or noise occurs turning one way or the other or both? If it comes on during the turn then the ABS sensor in that wheel or both wheels need to be inspected and possibly replaced. Finally, you need to inspect the brake pads for wear..typically however brake pads have WEAR INDICATORS built in and will start to SQUEAL when you apply the brakes telling you time to replace pads. If its a squeal and not a crunch then have pads replaced. Finally, be sure and make sure you dont have any rocks or road debris within the brake area or between teh pads and the rotors. That would be your final area to review for a CRUNCH noise.

2002 Suburban 1500 - ABS Light On

No doubt the control module is out, and it continue to operate when the ignition key is off due to a circuit fault. You can disable it easily by pulling the 60 amp fuse in the under hood fuse box (it is listed on the panel as ABS). Note that this disables the ABS braking feature and traction control, so be very careful when driving. The part can be purchased on the GM global parts site, about $600-$700 for the module. This will be the second time this has gone out for me and GM is not sympathetic, rather "pathetic", for a part to fail so often.

Very loud Hum under driver side

There is an ABS fuse under the hood that you can take out, and the noise will quit. The noise is accually your ABS pump. They are kind of expensive.
