Question ABS light on

Hey guys, I am usually in the 04+ section but i have a question for you all.

I am going to look at a F-150 for my brother this Friday. Its a 1999 f150 4x4 5.4 with 95k, I talked to the guy and he said the the ABS light is on....

What could be causing this? I was thinking that it could be one of the sensors on the front axle or rear diff?

Also in 1999 did they begin with 4 wheel abs?....I know my 97 only had 2 wheel

I will try to get the code read when I take it for a test drive and stop at auto zone......just wondering if you guys could give me a heads up on what it could be

Here's the link to it......XLT F150 99 White 95k miles 5.4 V8 4x4

Thanks guys


-Josh

4WABS was an option for many years. The only way to determine which system is on a truck is to inspect it.

Don't wast your time at AutoZone, their scan tools are worthless for ABS systems.

Most common reason for an ABS light is an open rear diff sensor. Check it with an ohmmeter.

If it's a good deal, get it. My 99 had 3 sensors, 2 in the front, 1 in the back. I did break one in the front before. After I got my wrangler MTR's I unhooked the ABS anyway. The ABS on the 99's was BS anyway.

Thanks for the reply's, I will bring my ohmmeter along and check them out....I was thinking that the rear diff one would be the most common....AS for the price I offered 5900 over the phone and he said he would take it.......I go to take a look at it on Friday.


One more question....Is the rear ABS senor the same as the speed senor?



I will let you know the out come on it.


Thanks

The rear ABS sensor is on top of the rear axle.
