My ABS light and my Break light are coming on randomly while driving. I drive all highway and dirt roads. Only 20 miles a week on dirt roads. While driving my abs and break light are coming on staying lit for a few seconds and then turning off again. I did however have my ABS light turn on this afternoon for 40 miles and when I shut the truck off and restarted 10 min later it didnt re light. BUT it has since still showed up with the break light randomly.

All fluids are fine as well as pads. Where do I go?

Truck:
2007 Screw with 41,000 miles Lariat 5.4L
Bought it Certified Pre-owned ford a Ford dealer.

I hate to go thru them for anything because well they are the dealer and I have already been thru them for other things and had troubles.


Thank you all,

Could be a problem with the fuse, I would check that out if I were you.

 

Check your wiring harness for any corrosion, I had a similar problem and after the tech replaced my abs sensor, abs module etc.. it turned out to be a wiring harness corrosion issue. A wiring harness is a big remove/replace so be prepared for $$ if you have no warranty left. Also check for loose connections, a friend has a similar problem as mine although there was no corrosion. He was off warranty and had actually purchased the wiring harness and decided to double check the connections, turned out to be a loose connection. Luckily he was able to return the harness for a full refund.

 

Thank you, I will get on your suggestions today.

Should I begin with the connections on the abs sensor it self and work my way back to the ECM and the Master cylinder. Would giving each connection of Di-electric grease help as well?

Thank you for helping me out here!

I know a lot of guys start with replacing the ABS sensor by the rear differential. 20 dollar part. Do a search on this and you will see tons of info.

(My ABS just came on too, so I have been searching a lot)
