1997 4.0 Ranger - ABS Light

[cal74]

Have a '97 rear only ABS

Light came on a few weeks ago, master cylinder level is fine and about 10,000 miles ago the fluid was changed.

Replaced the sensor on the back diff and the light is still on. My code reader wouldn't read it, brought it to O'Reilly's and there's wouldn't work. Brought it to a local shop and their SNAP on reader wouldn't work. He mentioned they'd have to bring it in and hook it up to a different power source.

Tempted to just pull the bulb, but any other suggestions? Possible I received a bad sensor, but ? Not sure what else to check, all the wiring looks good that's visible.

Thanks

RABS valve could be fried.

Adsm has the best advice about RABS! Removing the bulb is after you do the actual fix to the problem lol. (Bad engineering) But it is your truck, life and l brakes you're messing with.

I CAN believe I'm going to get to do it again on the truck I just got but not until I start having trouble with it. it seems to work okay at this time it's a 94

So what is the "RABS" and where is it located?

Rear anti-lock brake system??

Somehow, I feel like your question is meant to be humorous, but not sure. As to location, I would say the system components are scattered around the truck - sensor in rear diff, control valve on driver side frame rail? And some mysterious control module somewhere? Might be in "the cloud" these days. [emoji3]

Acronyms are great until you don't know what they stand for. I was hoping a nudge might get some clarification for those members and future readers that are unaware of the meaning...not that that would be me...nope...I'm not ignorant...well, maybe just a little ignorant. OK, a lot ignorant on a lot of subjects....lol.

Ignorance is nothing to be ashamed of, it can be cured with knowledge. [As long as your mind is open!]

It's inside the frame rail below and slightly behind the master cylinder area, the one in my truck magically disappeared, curiously there's a new brake line where it used to be RABS should be spelled POS and it's a PITA to work on, and one of the major reasons rear brakes lock up and drag for mysterious reasons. My van had true abs not to be confused with RABS,

I don't know it all either. I still don't know what SLA stands for in relation to front end suspension design. But the only front suspension I want is solid axle or twin traction beam.

Thanks Denise.

SLA = Short Long Arm = "A" arm type suspension, usually the longer arm is on the bottom and the short is on the top to provide a good camber curve with movement of the tire.

"Rear" = RABS, basically worthless
