ABS issue after 60 mph

I had this same issue and it was due to the fact that my rear tires had a lower series profile.
I had 45 series tires instead of 55 series tires.
As soon as I changed the rear tires back to 55 series the issue was solved. No more Abs light, brake light, and traction control lights illuminating when I was constantly holding the speed of 60-65 mph.

My first thought was that you had mismatched tire sizes and a T/C issue. With the combo above ^^^^ and no T/C, it may mean a sensor problem IMHO.

ABS and brake lights will go off in an 03 300a if the sizes are of. Posted a thread a while back about this. Doesn't sound like you issue though.
No I didn't rotate the tires the front have the stock sizes but the rear I didnt find the stock sizes so I put 255/55/18 instad of 245/55/18
The lights comes on after I drove the marauder on the highway when I cross 60 mph two to five minutes the lights will came on

My $ is on the issue i ran into. Wrong size tires.
Didn't click when you mentioned tire size earlier.
Edit: search for threads started by me and it will come up. Think it was around October of last year.

I had the same issues you are having and I had the same code regarding the speed sensor mismatch.
When I put on my new front tires using the same stock size, they had more tread and were at the proper height. Thus, it was throwing the code since my rear tires were 255/45R18.
It appears that at around 60 MPH throws this code as the front speed sensors and rear speed sensors are seeing a different speed (MPH). Mine was a difference of 5 MPH between the front and the rear. Thus, throwing the code.
To remedy this, I ended up buying 255/55R18 rear tires and no more codes or lights illuminating in the dash. Make sure you have the correct series tires and they are within the so called threshold.
See the attachment for more info and I hope this helps as I got this from this site and made sure to save it.

Also the brand of tires used can cause the above issues if they are different and not within the so called specs.
Thus, I went with the Nittos....
I have 555s in front (235/50R18) and 420s in the rear (255/55R18).
The above PDF file is most valuable and the individual who put this together is top notch and a life saver. Thank you very much!!!! :bows:

I use on the front Hancock 235/50/18 but the tire on the car foe a year now but the issue appear recently ...
does the vibration causing the problem if the bearing on the hub have noise or need to change .. because when I change the brake pads I test the hub and I noticed a noise when i rounding the hub ..:mad2:
I've had no problems with running 255/45 front and back on my 300a. I did have a Windstar years ago that had the same issue. One of the teeth on the reluctor was damaged, at low speed the sensor still got a strong enough signal from that tooth but around 60mph that tooth "dropped out" causing the ABS to shut down and turn on the light.

Before you start changing the wheel bearings or hubs, please put on the correct size tires and see if this remedies your problem.
Speed sensor mismatch, to me, means one abs sensor is reading a certain speed while they others are reading a different speed. Different tire sizes WILL do this because of the difference in revolutions per minute at 60 mph (smaller tire will have more and larger tire will have less) and our computer does not compensate for it.

Same size tires will NOT cause this issue because there is no speed mismatch being read by the speed sensor, which is why running the same size tires on an 03 300A will not cause any issues. Once you go outside the computer's parameters by running different tire sizes that rotate at difference revolutions, the issue starts to creep up. I am not 100% certain this is his issue, but it is a cheap and easy place to start and I still have my $$$ on this being the issue.

i just realized you are in Saudi.
That said, go the automotive/tire (benshir) area and have some hindi or sa'aeedi throw on all the same size tires (even if they are used and crappy) for SR 100 and see if you get an ABS light above 60mph. If not, you know just found your issue...
