RABS valve closed code!
Hi guys. I am having problems with my RABS for my 92 Ranger 4X4 with a 4.0L. I pulled code 4 which points to a closed valve. Which makes sense beacuse that is the only code that will show if the parking brake lite is on along with the anti-lock warning lite. Which is exaclty what is going on with my truck. So my question is . . . with the RABS valve closed, will that stop my rear brakes from working? I noticed that the truck doesn't stop as quick as I would expect but then again I've only had it for 4 days so I really don't know what feels normal for this particular truck. If it is stopping brake fluid from flowing to my rear brakes, is there a way to get the RABS valve unstuck?
Thanks for any suggestions anyone may have.

I have it as....
PINPOINT TEST H: DIAGNOSTIC TROUBLE CODE (DTC) 4 — GROUNDED/OPEN RABS VALVE RESET SWITCH CIRCUIT
and would suggest running the pinpoint tests.
I don't think it would cause you to lose rear braking, it is common to have problems with the adjusters and the rears get REAL loose and don't work.
Check out some of the stuff I have on the RABS in the tech info thread.

Thank you for your help Ken! According to the Chilton's book, code 4 means closed valve either way it isn't working the way it should be. Is Chilton's repair guide a good reference anyway? Also where can I get more info on the pinpoint tests?

Ken I received your email but due to the fact that I have not been a member for more that 15 days and have not had at least 15 posts, I cannot email you back. If you can please email me the pinpoint test I would much appreciate it or let me know where I can find it for myself. Thanks
