ABS Test
91 FSB 5.0
Recently my abs light cam on along with my emergency brake light.
After doing some research and searching the forum, I havent really been able to pinpoint the testing.
I read in the haynes manual about a test i can perform with the black/orange wire, but i can figure out what all i need to do with it. It says to unplug one wire and run a jump wire. The orange/black wire isnt plugged into anything its just sitting there so i didnt know if its supposed to be like that or not. From what i understand, all i need to do is run a wire to the black/orange wire and start the truck and ground it for a couple secounds and it will blink the codes. Is it that easy?
Also in the past i have been able to move the float in the master cylinder reevour and the lights will turn off. Not working now. Is there a way to clean the resevor? I new resevoir is 40 bucks from ford. Any suggestions on getting a clean one some where else? Also will i need to bleed the brakes if i can clean the resevour?
My front suspension sags so the alignment shop can only align it so much so my wheels get worn at a slight angle. Say all this to say i rotated the tires a week or so ago. Then the lights came on. Would this effect the lights turning on.

Seeing that its a 91 you have RABS not ABS.....so in your case 75% of the time the problem is with the VSS located on top of the rear diff. Pull it out and clean it off.....could be some ***** on it???? Then remove the neg cable from the battery for a while to reset the codes and see whats what.

this may sound stupid but the same happened on my bronco and after months of not being able to figure it out it turned out to be low on brake fluid, simple as that! give it a check it might be that easy.
