abs light / traction control

[cobraetti]

ok the abs light has been on for a while so today I painted the calipers and cleaned the front abs sensors, for the heck of it I disconnected the battery. Reconnected and the light comes on instantly, now the traction control light is off (it was on before) but the traction control doesn't seem to be active?

are the rear tires taller than the front, I'm running MT 295 on the back and 245 on the front, it activated my abs light, and tc is no operational.
. however i need to be going over 40 mph before th abs comes on and then stays on untill i turn car off.

 

[cobraetti]

18 front and back 275 on front and 285 back im going to put 17's on in a few days

Did you clean the rear abs reluctor rings?

 

[cobraetti]

no ran out of light ...what are the reluctor rings

 

[snakeraper11b]

Just do a quick Google search for abs reluctor ring, I don't want to get into all the science behind it. They are outboard on the front axle and inboard on the rear cv's. Just hit them all with some brake cleaner. You'll clean the sensors in the process of cleaning the reluctor wheels. They're only about 1/32" away from each other.

Update

ok had the ABS checked today here is what :

the scanner could not communicate ? disconnected the module and checked for corrosion looked ok. disconnected battery and checked light comes on immediately so im thinking module?.

I was thinking of swapping the one in my 2001 cobra just to see

Pretty sure that would be the module my 01 had this happen a year before I sold it scan tool would not communicate. There used to be a sticky on this in the new edge section. You can either look for a used one, or send yours out to be rebuilt.

Could not communicate with module means the abs module is bad. Common problem with cobras and mach ones, just snag up a used one and swap it. No biggie.
:beer: had to do it on mine, takes about an hour. Be sure to bleed the brakes.

 

[cobraetti]

makes sense got one on order


thanks guys

I don't think you even need to open up the brake system. Just swap out the module mounted to the abs "pump" I think it is?

Correct me if I'm wrong

 

[cobraetti]

^^^ hoping to shouldn't be a big haslet

 

[cobraetti]

ok changed out the module and light went off until I stated moving forward. Before the module change the light would come on instantly now only when the car moves???

oh well

 

[cobraetti]

had the code read again came back as faulty module ? it was used of course jez this thing is killing me

 

[BlksvtCobra01]

You do not have to program the module do you? Also i'm sure you checked but it was from a Cobra or Mach 1 right? GT will not work.

 

[cobraetti]

yes it was a cobra module and I was told by the shop that ran the code we didn't have to program the module.

Ok just checking I know when I replaced one in a Windstar years ago it had to be programmed.

Think I am going to send mine to him.

I researched last year cuz trac control does not turn on & occasional ABS light. I swapped master cylinder & fluid, cleaned all sensors.

The symptoms of a failed module on a Ford Mustang
- ABS warning light lit on dash
- TCS off warning light lit on dash
- Inability to communicate with the ABS module through diagnostic software
- Intermittent problem that becomes worse over time or only happens at certain temperatures
- Loss of ABS functionality (wheels lock up when braking on ice or loose gravel)

Update

second module installed light still on ! omg

why would the 1st replacement = light off until moving forward a few feet

2nd replacement= instant abs light ok I miss my 01

Hmm....chance of getting 2 faulty modules are slim to none. Did you buy the modules yourself? Are you SURE they're not using GT modules?
