I am having RABS II problems as well. I replaced the rear sensor and still getting the light. I found the BK/O wire connected to the Red wire on the pass. side kick panel. Tried the diagnostic several different ways and could not get the ABS light to start flashing. I have a 97 F150 that was actually purchased in Feb. 96, so I don't know if that makes a difference.
I noticed in several posts that the diagnostic has to be started while the ABS light is on. I tried this yesterday. When I drove into the driveway, the ABS light was on, so I left the truck running and disconnected the coupler, grounded the BK/O wire to the chassis with no luck.
Others just say turn the engine to the "run" position, the light will come on then go off, then disconnect the coupler and ground the BK/O wire. I tried grounding to the chassis as well as to the NEG. terminal on the battery with no luck.
I called a friend of mine who works as a service writer for Ford. He asked a technician about the diagnostic I was running and the tech said it was only good on '96 and older trucks. There might have been a lack of communication as we were on cell phones.
HELP! I hate to take this to dealer and get screwed!
