Can anyone help with troubleshooting a problem I'm havin' with an abs light that's on constantly. My speedometer doesn't work periodically and I think my ABS is not working at all (occasional rear wheel lock-up in slippery conditions). My local dealer says it will cost almost $1000 to replace the ABS control module and I'm skeptical because of the cost. Could it be a sensor only or is there anyway to tell?
Can anyone help? 2000 F-250 Crew Cab 4wd

 

By the way does anyone have any feedback on the Edge "juice" programmer for the 7.3 liter?

 

It sounds like you may have a speed sensor going out. It is located on top of the differential and looks at a toothed wheel located inside the differential. It provides input to the speedometer, cruise control, ABS......anything that has to do with speed.
I've read of prices anywhere from $20 - $40 for them. That's where I'd start because the speedometer itself has nothing to do with the ABS module.

 

What touchofgrey said. If the ABS unit were failing that would be the ONLY thing that is acting up. But with your speedo quitting at the same time, it's the VSS.

 

Thanks guys & Iknew there would be a better solution to start troubleshooting instead of the Dealer always wanting to just replace everything from the start. It wouldn't be such a bad idea to replace it all if you had unlimited resources but I would rather spend my money on something to make it go faster and tow stronger!

 

Check NAPA for the VSS. I got mine there for about $11. They carried more than one brand. I can't remember what they called the part, wasn't "vss". Make sure you tell them it is located on the top of the rear axle.

 

Thanks - Whitmo -
I'll post my results after a new vss is installed. Hopefully I won't have to visit the dealer again, everytime I get some absurd estimate.
FYI two months ago I took my truck in for a grinding/ rattling noise when 4 wheel was engaged and got a quote of $865 to replace the front drive shaft. After a little research I found a rebuild shop in town that charged $220 for a complete rebuild. I've tried two seperate dealers for quality of service but they all are interested in charging the maximum for repairs.

Thanks for the Napa tip.

 

A while back, my 01 was losing the speedometer. Tried the speed sensor, same thing. Took it to Ford, comp. showed the speedometer module itself. They ordered a new one and it did the same thing. After 4 trips to the shop, the mech finally found the antilock brake controller had a whole in it. Problem solved. Truck had been wrecked and it had a crack in the module that let water in when i washed my motor.

 

Nubwon- I just ordered the VSS @ Napa (24.95). Where is the "Brake controller" located? I had intermitted flashes of the abs light and now a solid light. I,m wondering if I might have the same problem. Regardless I' gonna start with the VSS.

Thx!

 

Mine is right behind the drivers headlight. I lost my speedometer right after washing the engine compartment so i knew it had to be water getting in somewhere. I first tried unplugging and spraying something to dissipate water, then blowing out all the electrical connections i could find under the hood...man there are a lot of plugs under there lol. Good luck with yours, let us know what you find!!

 

Well, Champion Auto had the correct sensor that I needed. Every little glich went away after I replaced it. The part was $13, you tell me weather my dealership was trying to overcharge me for parts that weren't needed.
$13 and a little advice from you guys really helped me out. Thanks!
