Question about 2001 Chevrolet Suburban

2001 suburban abs motor will not turn off

I got out of the car one day and heard something running. I was out of town and it was late Friday. The local dealer pulled the ABS fuse and advised I get it looked at when I got home. Upon returning home I was advised that it might be a failure of the ABS relay and that before spending a lot of money I should swap the A/C relay with the ABS relay to trouble shoot it. I see the A/C relay in the fuse box but where is the ABS relay?

Thanks

    We went to move the Suburban from one parking spot to another last night in front of our house and it began making an unusual noise, which continued after the ignition was cut off. We had a similar problem in 2004-2005 and can't recall what the fix was. We think it was ABS-related or traction-assist. The noise stopped after disconnecting the battery, of course (to save the battery drain). The dealership said electronic brake control sensor might be going bad.

The ABS relay should be located in the fuse box located on the drivers side inner fender in the engine compartment. Lift the lid and check the location diagram on the inside cover to locate the correct relay/fuse.

A related issue may be a loose ground wire. There is one located on the top rear of the engine block. It is a bolted connection. Remove this bolt, clean the surfaces and replace. This simple step has cured many electircal issues on these trucks.

The problem is the abs module. When the module goes bad the pump will run continuously. The only way to fix the issue is to replace or rebuild the entire module. First go remove the abs fuse (fuse box under the hood) temporarily( so your battery doesn't run down). It is still safe to drive, but remember you only have standard brakes now, not abs, so allow plenty of room for braking. You have then got to replace the abs module or find a rebuilt one. Don't try to repair the module yourself.Too many things can go wrong. If you can safely remove the module, contact module masters online and they will rebuild yours for around $150. Thats a good deal by the way. Most suburbans and yukon xl locate the module under the car below the driver seat. The brake lines can be difficult to remove an can get bent up. Remember to mark which line goes to what port so reinstallation isn't as hard as I made it with mine.

    It is the EBCM the elecronic brake control module. I had the same problem on a suburban 2001 and a silverado 2004. I found this company on ebay that offer to fix your EBCM and replace a relay with a better one. It only cost me $75 shipping. To start you need to diconnect the EBCM fuse in the electrical box in the engine compartment so you don't burn the ABS pump and then remove the 4 torx screws that hold the EBCM to the pump, disconnect the wires and ship it to get repaired. Cover the pump with plastic wrapand tape to prevent dirt from getting in. you still can drive the vehicle you will have braking but no ABS. The company's name is ATE, if you call the company directly it will cost you about $165. If you go through ebay auction the you only pay $75. Good luck

HI,When electrical components such as a stater motor get hot they draw more amperage thus making it harder to turn over the motor. There are 3 possible things going bad (1) Battery (2) Battery Cables (corrosion) (3) Starter. I hope this helps lead you to the proper diagnoses.

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

01 Suburban with abs system. abs light came on


A relay controls the ABS motor. You can trace the wires running to it. The next time you shut the engine off unplug the relay. If that shuts it off get a new relay for the old one will not open its circuit to shut off the motor to the ABS motor

It was the ABS system kicking in to try to keep the wheels from locking up. The squealing you heard was indeed the tires "sliding" across the surface in protest/resistance to your turning input thru the steering wheel. If you are not comfortable with that feeling go ahead and take it to the dealer/repair shop and have the ABS system checked/tested. (preferably the dealership)

Engine shutting down in extreme heat


Mine does the same thing as far as shutting down on long trips---usually 1 1/2 - 2 hours. I don't think it's overheating....it's got something to do with antitheft system

Abs relay


Good Day,

The easiest solution is to locate the abs fuse in the fuse box. Remove that fuse and ABS is now disabled(this will trip you abs light), brakes will function normal but keep in mind you will lock the wheels up under heavy braking. Possible cause are bad abs sensors, or bad abs module. If you don't mind no abs then problem solved, otherwise take it to a shop and have a code pulled from the abs module to diagnose further.

Hope this helps and Good Luck
