Did you read Ch9-Sec14.2: "RABS II module part numbers begin with F3TF-2CO18 or F3UF-2CO18; all other RABS modules should be considered RABS I."In reply to:
Today I went out and pulled the diagnostic code from the RABS1 computer in my bronco. I read 9 blinks, which my haynes book tells me is a "Open speed sensor or Harness". So I might have to replace the speed sensor instead of just cleaning the metal shavings off. Once I have a methoid of rasing the truck I can figure more out.
Another thing I am wondering about is this: The haynes manule says "The diagnostic connector has two mating halves. . . disconnect the two halves." Mine doesn't have the two halves. I only have the one half with the black/orange wire in it (male connector inside a plastic boot). I looked for the other half of the connector but the only thing I could find was a black/green wire (with a female connector) which was pluged into the parking brake.
So could my lack of a matching connector for my black/orange wire be part of my problem?
Okay I deleated my post. I didn't want to hijack this thread, but whatever.In reply to:

Have you looked at illustration 9-14.20b? If you have RABS I, that BK/O wire should have been connected to a R (red) wire with a matching connector. The red wire is the KAPwr wire. Did you read the Note at the end of 9-14.1, just before Pre-Check? "Some problems such as those associated with brake fluid level or loss of power to the module will cause the system to be deactivated and the YELLOW ABS light to be illuminated, but will not provide a diagnostic flashout code."
How about the note at the end of the Pre-Check (end of 9-14.8)? "A blinking yellow ABS light indicates loss of Keep Alive Memory power (RABS II only)."
Why do you need to raise the truck? There should be plenty of room to crawl under or roll on a creeper to get to the rear axle from the front side. From there, you can trace the wire that's clipped to the e-brake cable to see where it's broken or shorted. That code doesn't necessarily mean the sensor is bad - you should look for an "Open harness" before assuming you have an "Open sensor".
BTW If a new sensor is more than $30, consider a used one...
