ABS light and traction control light are on.

[04redfireRO]

Hey guys ,all of a sudden my ABS light and T/C light came on. Do you all think it could be just a wheel sensor or the ABS module(i hope not cuz it will suck)? My car has only 22k on the dash.

Anybody had this problem before?

Thank you!

Yes I had this exact problem...Its a sensor in the rear...Either the right or left side! Replaced mine and problem was fixed! Hope this helps u out

 

[04redfireRO]

Thank you sir.

 

[BlownShelby10]

No problem man! If you have any trouble just pm me

Do you remember when you had this problem, your ABS light was on at start up or it was coming on after the car was moving. Reason i'm asking is that mine comes on at start up and stays on.

Yeah man...and to know for sure if its a sensor...Unplug your battery for a few, then hook it back up and see if the light goes away...Then go for a drive and see if it pops back on and if it does its a sensor!

Where are these sensors in the rear located? I have had my abs light on for a while now

in between the irs ...if i remember ill take a picture tomorrow for u guys!

I have the same problem but how are you sure its the sensors on the rear and not the front?

Hook up a scan tool to the computer and what the error code is. It should tell you which sensor it could possibly be.

^^^IIRC, you need a special one for the brake system.

I know its the rear bc I changed mine and fixed the problem! I mean his could be a different problem but what I did fixed mine so, I was just giving him my .02 on what a did to fix mine!

With it affecting the traction control system, I would imagine it's in the rear like stated above.

With it affecting the traction control system, I would imagine it's in the rear like stated above.

The traction control turns off when ever the ABS system detects a faul. It has nothing to do with the front or rear.
Also the entire ABS system turns off when it detects any type of fault in the system. If you understand how the ABS system works and how the traction control system works (both are very primitive in our cars) you'll understand why it shuts itself down. (SAFETY)

(Edit)
Eh.. I'll post how it works lol.

-Traction Control-
When any of the four ABS/traction control sensors detect that a drive wheel is spinning at a rate higher than its counterpart, ignition spark is retarded and the fuel/air ratio is modulated to attenuate torque delivered to the slipping tire. If the condition persists, cylinder cut-off occurs, brakes are applied to the wheel with low friction, and power is transferred to the other drive wheel.

-ABS-
The Mustang has a 4-wheel anti-lock brake system (ABS). The system operates as follows:
Prevents wheel lock-up during an emergency stop by modulating brake pressure.
Permits the driver to maintain steering control and stop the vehicle in the shortest possible distance under most conditions.
Activates with varying brake pedal force to engage the ABS function depending on the road surface conditions. A dry surface requires a higher force, while a slippery surface requires much less force.
The driver will sense a pulsation in the brake pedal during the ABS operation.
The pedal effort and pedal feel during normal braking are similar to that of a conventional power brake system.


You can go to most major auto repair shops and have them hook up a ABS code reader tool to your car and it'll tell them exactly what is causing your system fault down to the exact part and location. Usually it costs $75-125.

Really? I guess that makes sense cause it's not the mil. I know on some older cars you can jump pins and pull a flash code.

I have the exact same problem with mine, assumed it was one of the rear sensors but I plan to swap sensors when I do my sra swap next month and see if that fixes it.

Hey Yellow2003Cobra thank you for the answers.It looks like i have what you said,i was just too lazy to hook up my scan tool last night.
Today I hooked it up and this is what it showed:

Rear right sensor.

ANYTIME MAN...glad I could help you out!

If you need the location pm and I can give you exact location...There kinda hard to get to

My ABS light goes on / off intermittently. Doesn't seem to have much rhyme or reason. A few weeks ago I swapped out the front system to the 14" Monobloc Brembos with new rotors, calipers, pads and the rear with new slotted rotors and HPS pads. Truly amazing performance improvement with the new brake system (but that is for another post).

As for the ABS I used to notice (prior to Brembo swap) when I was pulling up to a light the pedal would vibrate very lightly under foot. Almost like a really mild ABS action but I'm talking about going like 5 mph and definitely not triggering any type of slip / traction situation. Anyone feel that before in the brake pedal under light braking?
