hey guys i have an 07 F-150 with only 50k. about 3 weeks ago my abs light and parking break light come on and off sometimes it'll stay on for days and sometime is off for days, i tried hooking up a computer but no code came up. Has this happened to anyone else?

Welcome to the forum.

I would start with the simple things like making sure there is the correct amount of brake fluid in the reservoir and then move on to ensure that all the connections are solid at the ABS/HCU unit.

Remember to check the wheel speed sensors at the front (The harness connector is located in the engine compartment secured to the fender apron.) and rear (on the front side of the differential) of the truck.

Hope that helps.
hey thank you, i did check everything but i did also put a after market radio with tv dvd and gps do u think that might be part of the problem?
It could be if you crossed up some wiring but if you reused the same connectors there then I doubt that would have anything to do with it. Was the new unit a plug and play installation or did you get into the wiring?
