Question 95 blazer abs light

I have a 95 chevy blazer 4.3 4X4 auto and the ABS light is on it has been since i purchased it. I recently just the ABS sensors on both sides and disconnected the battery to reset the system. I also traced all the wires to see if there was a break in it anywhere. Still no ABS and the light is on.

Let's see...

With some of the older kinds of ABS, you can jumper a couple of wires on a connector and read out the codes from the flashing ABS light. But you would need the factory service manual set (order from dealer or helminc.com) to tell you what the code(s) was for. You may find this information on the internet? Be sure it is for your specific vehicle and ABS system. (Some vehicles may have one of two types of ABS and the codes can mean different things depending on WHICH ABS it is!)

Otherwise your best to take it to a dealer to at least read the code for you and tell you what the problem is. Find out what their diagnosis charge is first.

Then at that point you may be able to fix it yourself. Or you may need the troubleshooting instructions in a factory service manual set and a multimeter.

If the ABS unit is toast, there are places which rebuild them. Like at the following link. Might want to poke around there...
ModuleMaster rebuilds ABS modules for as low as $100, 2 day average turn-around, 5 Year Guarantee

If you need to replace the ABS module and rebleed all the brake lines, there are exacting instructions for doing this and probably would require special tools. Probably best to have that done at a GM dealer.

I've seen some new engine code readers on the internet which can also read ABS codes. I don't know if these would read the codes in a 95 though? (96 and later is called OBD II and these would probably be like that???)

The most common cause on those is the abs relay unfortunately it is part of the modulator valve (located on the left inner fender well) you can check the wiring to this for power ect. ect. you can pull the abs codes by grounding(jumper wire)the top right pin to the second from the left on the bottom pin IF yours has the pcm controlled abs if your diag connector doesn't have pins in those locations (the same one for engine) you have to have the abs scanned there is no other way to get codes on that version.The abs light will flash like if you were checking engine codes.Here is what they mean. Good Luck

What exactly is that you did? Just the ABS?
