Question about 2002 GMC Sierra

Open Question

ABS and Brake light stay on in my 2002 sierra

2002 Sierra with a 6.6 Duramax Diesel and a 6 forward one reverse speed manual transmission.
Problem started with ABS kicking in at low speed when coming to a stop. GM maintains my vehicle is not part of the speed sensor corrosion re-call even thought I am in Ontario. One day the ABS and Brake light came on. I assume the ABS is not working anymore because it does not kick in at low speed anymore. Other problems which I think are associated: My speedometer; I will be doing 100km and it drops down to 30km and at the same time my radio volume drops and if I apply my brake the pedal is right up and very hard to push down. My tach works fine, in fact I use it to know what speed I am doing. 2000 RPM in 6th gear is about 100km/h.

SOURCE: right rear wheel locking up

okay you had brake work done!!! "THINKING" that was the problem originally right rear wheel locking up! okay,,, so doing brakes has not solved your problem! I would maybe look into rear end bearing??? do you have any load road noise from rear and do you have rear end fluid in differential? question to you was the baking plate ""WET"" looked damp? or moister get at it!??? seal might have leaked all fluid out??? all the above would be good place to start! good luck I hope this info helps you out.Happy new year.

Have you by chance checked your fluid? If not, you may want to do that, it could show that you need brakes if it is low. If that doesn't do it, the mechanic may be right about a sensor, but just the wrong one. Hope that helps.

does the abs light come on ? there was one cause on the van that i owned (ford windstar) that can happen to any vehicle. the ring that the sensor reads from can become crack. that causes the teeth to not be aligned properly. just curious... have you had your brakes replaced recently ?

SOURCE: trailer brake controller problem

I found the problem. Talking with a technician from the controller company, we determined that it was a fuse problem. I found that the fuse to the CHMSL was blown.

ABS problem with GMC 2002 Sierra


its a low speed abs activation the problem is in the front sensors they need to be cleaned or replaced they [or one] probably has some corrosion on the sensor --[the 99 chevy tahoes had a limited recall over this issue and the fix was to remove and clean the abs sensor or if to corroded replace ] this problem doesnt set off an abs code or trouble light also sometimes the abs will activate by itself at under 4 mph without even touching brake

2002 GMC sierra brake lights not working. Reverse and blinkers ARE working!


Check fuses first. If thats OK, could be a problem with the brake switch (down by the pedal) or the wiring.

Excessive black exhaust on 2003 GMC Sierra Duramax Diesel.


This is what i would try (cheapest first) redexe/wyyns
injector cleaner,double dose,then i have put 1gal gas in 10gal diesel to increase burn temp (you may encounter a hot start problem temporarilly)then if still smoking, get a compresion check on the engine(this will tell you volumes)
by the way the NATO tanks put in 1/3 gas in diesel to stop it freezing in arctic conditions.any more than 1/3 can result in problems.

Brake pedal vibrates while braking and doesent stop right away


There's speed sensors at each wheel. You may have got some contamination in front of one of them... sounds like the abs is trying to compensate for un equal speed at each wheel... and something may be blocking a proper read at one of the wheels...

2001 GMC SIERRA . ABS LIGHT STAYS ON


Wheel speed sensors misadjusted, damaged , or metal shavings and other debree, since they are magnetic can give false readings from one of the wheel circuits. Over sized tires can give of false speed readings as well. there are many other causes including bad relay, control module, e.t.c. It is best to have the proper scan tool to diagnose an ABS problem
