My 05 4wd 5.4 has abs light randomly. Read code its b1155 LF malfunction. Autozone gave part # for duralast su8784. I cant get pn to cross over to any other pn and i refuse to run duralast parts. Anyone have another part number they can share?

 

Not sure what the problem is, but many times the wheel sensors get dirt/mud/brake dust on the brake sensor. I'd remove that left front wheel and inspect before I buy anything.

 

B codes are usually body codes. Are you sure that code doesn't relate to a subwoofer problem? No clue what part numbers you are referring to.

 

Part number was for wheels speed sensor made by duralast. Doubt the problem is with subs since my system is all JL Audio.

 

Sorry none of my documents cover body or chassis codes. I would start with what Bucko posted.
