'95 buick abs

I just bought a 1995 buick regal and the abs sensor on the left front wheel was disconnected, so I connected it, the abs light is still on. How do you reset the abs, do I need a scan tool?

Yes, you do need a Tech 1 to read the ABS codes on the '95
Buicks. Since the wire was disconnected I'm guessing the light
is on because an open circuit is being detected on the left
front wheel speed sensor. I don't have a list of the codes, just
the diagnostic charts (Chilton's Total Car Care). You need to
have the car scanned and the codes read. I think you'll probably
end up with a bad left front wheel speed sensor or the wiring at
the very worst.

Make sure all the brake light lamps are working too, including
the third brake light in the back window. On my 1996 Century,
the ABS light stayed on if certain lamps blew out (found that out the hard way, lucky the guy didn't charge me for the scan! I swore that I checked all the bulbs before I came to his garage!)

When I do my own work I buy my parts at Autozone, they can
scan the codes in your Buick and reset the light for free. When
I don't do my own work, there is an excellent PEPBoys near
my place that does really quality work. (I only had to take the
car back once because I didn't like the tires they put on the
front of the car (35psi instead of 60psi), but they swapped the
tires the next day without a problem!

Thanks, I'll hit Autozone tonight. The dude I bought it from said it was like that (light on) when he bought it, brakes worked fine so he ignored it. I immediately saw the wire hanging and reconnected. Breaks work, but no antilock. I will see if autozone can reset it and go from there!

Great! Your location doesn't show, so I don't know if you
live in the snowbelt or not, but the biggest thing I've noticed
about the ABS is hearing the pump operate to bring the
pressure up when I start the car. This only happens occasionally, but it's enough to tell me the system is working.

I get a lot more ice around here than snow so when the weather gets bad I'll take the car out on the street and jam the brakes on
while doing 10-20 mph. This is usually enough to active the ABS,
light the "Low Traction" Idiot light and get the system to pump
the brakes. If everything goes right, I'm happy for the rest of
the year!

Autozone only read engines codes on obd 2 vehicles 1996 and up.Maybe the terminals are corroded from being diconnected.I think a independent shop may be able to pull codes with their scanner.If not a dealer can read them for you.

I believe that system resets itself every time the key is cycled. It goes through a self test every time the key is turned on so if the light is staying on then there is a hard code and something needs to be fixed. Once you turn the key off, the code is gone and will be tested again the next time the key is cycled on. I don't think it holds any memory codes.

Autozone said they can only read check engine light, not ABS. I believe there is a problem. Now that I think about it my '98 GMC had the ABS light come on--I had to remove the sensors and clean up the rust behind them--once it was back together the light reset itself.

That car carries a Delco VI ABS system. It will reset itself, but only after I believe 100 key cycles and driving above 10mph. I'd try that first, if the lite comes back on, you have a hard code setting.

Do you know if that fuse is under the hood, cause the sticker on the cover of the underhood fuse box is impossible to read.
