ABS broke, fix it or F*#& it?

My ABS light used to come on at random but a few months ago it came on and hasn't shut off since so I'm assuming something in the system is fubar. I've been fine without it during our autocross winter series and I really don't miss it (probably because I didn't have ABS in my fox that I had for 8 years).

I have a bulb out in my dash behind my speedo so I'm pulling that out this weekend to replace it and I'm so tempted to just yank the bulb out of the ABS socket and call it a day, thoughts?

I usually hit 2 autocross events per month all season long and I daily drive the car 5 miles each way to work.

If you arent using your ABS in an autocross you arent braking hard enough.

Pull the codes on it and fix it. http://www.veryuseful.com/mustang/te...sDiagInfo.html

And if you ARE using, you are probably slow and overdriving. It is a fine line...

That being said, the SN95 I have experience with had excellent ABS which turned quite a few massive screw ups into salvageable runs.

I'd fix it.

Fixing it will save you money from flat spotting tires if you are the type to overdo it going into corners ocassionally.

(who? me? I don't know what you are talking about... )

Thanks guys, my head is now officially out of my ass on this one and I'm going to get it fixed, it's so stinkin cold here that my lazyness has reached new heights with anything outside

When the ABS was working it was great, the Bosch 4 channel system isn't super intrusive but still gets the job done real well when I needed it. I just don't really miss it because I got very used to threshold braking without ABS in my old fox like I had mentioned. Oh and believe me I'm using the brakes enough, every event I've been at that I haven't had the ABS I've locked a wheel up once or twice, my buddy even caught me doing it with my camera...

Oops!

Here's the picture...



And here's video from one of the last events of the season last year with some up close and personal brake locking action

After a little detective work, I know which event that picture came from, and that it was from somewhere in the first "segment" of the course. What I can't figure out is if you were braking for the left-hand sweeper or the right turn leading across into the second segment. Or why your car is aimed the way it is

Got to ya a little (but congrats on your class win).

I've been running sans ABS for a while. IF you're using track pads, the abs helps when the pads are cold. As the pads warm up and become more liner, the ABS serves a bit less in function. It also helps when there are bumps in the braking zone....sometimes, in the wet, during panic braking, when the track gets greasy, and when you're locking up a rear tire and not realizing it.

It's hard to flat spot r-comps or street tires as long as you're aware of the potential of locking up a tire. I had some decent smokey stops, and I never had a problem.

I'm fixing mine now. I'm going to replace that front sensors (I think I scraped the wires, which are brittle as they are exposed to the elements) during a spring change.

I believe that was coming into that annoying little left hander box thing after the straight that was after the sweeping left hander. Did that make any sense?

Yup. Actually, I kind of liked that feature even though I know I left some time there.

Ciotti,
Cool vid. What are you using for a camera. I really like those body mount shots.

This might be a stupid question but oh well. How do I ground the wire on the connector? I've never done this and I would like to pull the ABS code. If I find the "connector" will there be an orange wire that is there or is there something that needs to be plugged in.

Ciotti,
I would suggest pulling the codes via the OBD plug port under the dash. Suggested tool would be an NGS (New Generation Star) scanner. Some auto parts stores have them and will go out to the parking lot and give you a quick scan. Certainly most repair shops and dealer would too.

Regarding diagnosis, one quick easy tell tail is if the light is off at start up and then goes on after driving it is likely a wheel speed sensor. However if a sensor wire is broken and fails continuity for the open circuit check then the light will be on from the get go.

Another quick thing to check is there was a water intrusion issue for years, where water would "wick" into the system via the ground wire on the radiator support. The wire harness crimp at the ground loop wasn't sealed and water would migrate down into the ECUs electrical connection. This can be inspected fairly easily by unplugging the ECU connector at the ABS unit and looking for corrosion on the pins/plugs.

my 0.02 ......

Mine comes and goes. From your post, it is most likely a wheel sensor?
