Question about Chevrolet Suburban 2500

1 Answer

I have a 1992 Suberban 4x4 454 auto trans. I have an ABS light that comes on at 10-15mph and goes off when I stop. I believe my vehicle has three speeed sensors two up front and one on tail shaft. How can I trouble shoot the speed sensors and ABS light?

    Yes itwas help full but its not fixed.

    I checked the resistance at both fron wheels and they were the same. I havnt checked the volts because I was not sure how. Ill try just spinning the wheel with my volt meter on the plug of the sensor. I also checked the tail shaft sensor and resistance was the same. I dont think my car has a sensor at each wheel.Ill also need to take it to a shop to have it scanned. If you have any other tips Im all ears.

Need scanned the ABS module for codes to see if a sensor may be going bad or you have a solenoid or pressure problem at the ABS controller or calipers.

Sounds like one sensor is reading different speed then the other. Have you checked the individual sensors at the wheels. Each wheel will have a sensor. Check the resistance in the sensor and the volts coming out of the sensor when you spin the wheel. You need to check it at the sensor though, because if you have no volts coming out of the sensor then your problem is probably inside of the sensor. Make sure all of the tooths ar still on the ring also (which is what the sensor reads).

Hope this helps.

Reset abs light pajero


When the ABS comes into play from heavy braking you will feel a pulsating of the brake pedal under your foot. This is the brake pressure, on off on off as the wheels stop start stop etc. The ABS will not control the vehicle direction but by allowing the wheels to turn under brakes and not lock up you have control of the steering and the direction the vehicle goes.The ABS will not stop you quicker and in fact on ice or loose surface the distance to stop will be increased. As I said all the ABS does is give you steering ability under brakes.. Take the vehicle to an accredited brake shop and have the ABS tested if you feel that it is no operating properly

The antilock breaks on my 2001 toyota sienna come on even when making normal stops on flat dry roads. what is causing this ?


For some reason the ABS module believes one of your four tires is locked up and skidding.
Do you have any warning lights that are coming on? I would suggest you take the vehicle to your local Auto Zone or Advance Auto Parts and ask them to scan the vehicle for trouble codes. Write the codes down and respond back to this reply and we can get started diagnosing.
Chances are you have a wheel speed sensor that is registering "0" mph when the brake is applied, that is usually the most common problem with your type of ABS activation.
Good luck, let me know when you have the codes.

My 1996 S-10 Blazer will not shift sometimes and the ABS light comes on. This problem goes away after I drive it for awhile. The code I get is P0502 (vehicle speed sensor low imput). Would a bad speed...


A faulty VSS (Vehicle Speed Sensor) or related wiring can cause both of your problems, trans and ABS. If the computer doesn't know the vehicle is moving, then it won't shift the trans. If the ABS controller sees wheel speed, but not vehicle speed, it will turn on the ABS light. The VSS is located in the rear transfer case housing. But remember, it may be the VSS, related wiring, a faulty speedo buffer (usually located in the dashboard), ECM, or even the reluctor on the transfer case output shaft. You may want to have a shop scan "data stream", or even have them diagnose the problem.

Abs and brake lights comes on


What you will need to do is have the system scanned for codes. Your local Auto Zone or Advanced Auto will scan the vehicle at no cost for you. Write the code numbers down and reply back.
When both lights come on, it is indicating one of the ABS sensing components is not operating properly. Your base brakes will be fine, however the ABS function will not work properly. No danger of base brakes not stopping the vehicle.
My guess at this point would be a wheel speed sensor faulty, but again, only a guess until you get the codes scanned.
Get the codes and let me know.

Can a replaced non programmed abs affect auto gearbox


The ABS control unit does need to be coded to the vehicle. After coding the control unit, an End-Belt run test must be performed. I know that you will also have transmission faults stored, because the Trans warning is set since the control unit has not been coded
and the control units communicate constantly during engine operation. The trans uses abs input for shift characteristics and helps with power reduction during evasive driving control. A dealer should be able to code and perform the end run test and usually charge about an 1hr fee. They will also need to quick delete other fault memories.

Abs releases brakes on dry pavement while coming to a stop


Just as it says...When I come to a stop, the abs releases the brakes, usually only momentary but occasionally I have to shut off the ignition to stop the vehicle. When this happens the ABS active light does come on and there are no DTCs, I do believe I found the problem tho, the right rear exciter ring is ground up due to wheel bearing failure and a lot of metal has 'grabed' on to the sensor itself.
