2005 Chevy Uplander ABS problem

My 2005 Chevy Uplander's abs system is engaging intermittently when you come to stop. sometimes during a straight stop on smooth road, other times while turning and braking. the abs light will come on the dash sometime but most of the time it's off. I've just had the brakes all replaced and rotors turned. any ideas? thanks Bill

SOURCE: ABS WARNING LIGHT ON VOLVO V70 1997

ABS light comes on with ignition then should go off when you start the car.
If abs sensor does not turn off after disconnecting the battery, then there is a real problem, a faulty sensor or ABS malfunctioning.
When the ABS led comes on immediately after you start the car and stays on usually is one of the relays.
The main one is called surge arrester relay, if it is faulty usually there have been an overvoltage.
There should be two more, usually located behind the black plastic cover of the ABS.
Testing and changing the faulty relay can fix the problem.

If light turns off on startup, and comes back on when you reach some speed, usually you need to check the wheel sensors. You test them unplugging the sensor located behind the wheel and testing it for continuity with a multimeter.
Use Haynes manual to find locations and specs of relays.
Contact a qualified mechanic if you cannot fix it yourself, problems with ABS may compromise safety of the vehicle.

These vehicles have a recall on the ABS system for faulty wiring. You may want to check with your local dealer to see if your vehicle is included.

SOURCE: abs brakes

does all break grab?? if so, the break master cyclinder need attention. if only one break grab then one of the break cyclinder need attention. the cyclinder is not backing off when the break is released.
do not keep driving the car if you don't fix the break. the car will lock up and going to cost you more.


if this answer your question. please rate the answer
thank you

SOURCE: 2007 Chevrolet Uplander LT ABS and TC light on

We were having this problem...have your wheel bearing checked out. There was a sensor in the drivers side wheel bearing...once we replaced it (because it was going out) the ABS and Traction Control warning lights stopped coming on.

I have a 2006 chevy uplander that had an abs light coming on so i took it to my local GM dealer to have it diagnosed and they had told me that the hub and bearing assembly needed to be changed, so i changed it and the light still came on. Upon further investigation i came to discover that the abs wires were frayed in two locations and that the connecters were loose i tightened the connecters and replaced the wires and now my abs light does not come on. I also discovered that i did not need a new hub and bearing assembly after all.

AB Light Keeps Going On


software? sounds like a bad wheel sensor, have the abs computer scaned for history codes to find the problem. most of the time its a abs wheel sensor that looses contact then starts working agian so light comes on and off, start with that good luck.

All Wheel Drive Disabled


I would take it back to place where it was repaired, it is possible that the part they replace is defective..

Also they should have clear all codes in the system at that time!!!

How do i turn off the abs light on a 2005 chevy uplander? replaced front pads and checked wires and connections. is there a way to see if the anti-locks are working?


Hello Abintz.
When your ABS light is on you have a problem in the system.
As long as the light is on your ABS system does not function at all.
If you have already checked the harness and connections the next thingt you can check yourself is resistance values at the wheel speed sensors.
One at each front wheel and one in the output shaft housing to the rear drive shaft.
They should read very close to 1000 ohms.
The front sensors are usually the area of most problems I see. They are replaceable.
Other than that you really would be hard pressed to find any other issues without getting it scanned by a repair shop.
If you have further questions please put them in "add comments and I will return to answer.
Best of the season to you.
