Background: I've got an 01 Blazer 4x2 with 106k on it. Drives just fine, lights on the dash are on..

Problem: A few thousand miles back the abs and parking brake lights started turning on and off. They seem to turn on and off every 50-100 miles, the truck brakes just fine, had new brake put on about 10k ago. I'm not sure what could be causing this but I don't see a reason..

I've heard that 01's seem to have this problem alot and I've been told before that it's just a computer malfunction? Any input is greatly appreciated!!


Side note: sorry if this has already been discussed, I searched for a thread on it and came up with nothing..

 

my girlfriends 01 jimmy does the same thing...talked to a mechanic and he said it needed a new abs module...havent tried it yet but thats what he said would fix it

 

We have a 2000+a 2001 and my 01 does the same thing, when the dash light's are lit
you will find the anti lock brake system does not work properly-but the brake system seem's
to work just fine-just NO ABS!
I do not know the cure-I believe there is a scanner for pulling the brake code(trouble code)
though I've never done mine-I'm to cheap! LOL Put some black tape over the light's-hehehe.

 

Good to know I'm not alone, wonder why it affects 01's?

Anyways, I thought it might have to do with the module but I dont really want to know what it's gonna cost haha. and yes, I've noticed that when the lights are lit and I hit the brakes real hard they kind of grind? cant really explain it.

Edit: But thanks for the info!

 

I just encountered this same problem in my 01 4x4 blazer, my emergency brake stopped working for me about a couple months ago. Recently I started getting the ABS and Emergency brake lights coming on at the same time. It might not be the same problem as discussed, plan on getting into the shop soon to get the codes scanned. How much do you think it will be to repair if it is the module?

 

Yeah my parking brake doesn't work either, as far as cost go I couldn't really tell you since i havent gotten an estimate, Frankly if its not something that effects my stopping (which is doesnt) it's not on the top of my to do list! Ive tried cleaning the brakes and etc but that didnt help at all.

 

I hear you, I'm really not trying to put a **** ton of money in my truck to fix a problem that really isn't too big of a problem if its going to be a lot of money. Going to the dealer ship around 1pm today to get the codes scanned and i'll find out from there what the problem is. Hoping its nothing expensive, was finally about to get some sub woofers in my truck but if this is an expensive fix I'm going to put them off again.

 

Sweet man let me know what they say!

 

Bad news, they said the ABS control unit needs to be replaced which i'm looking at spending $1,000 for part and installation. They said it doesn't need to be fixed right away, but I should get it fixed before next emissions which isn't for a good while though. Something like $250 for the emergency brake, I got a print out of the estimations.

 

That's no good... Maybe get a second opinion on it though.
