Does any one know what 9 flashes for the Rear Antilock light means?

 

9 = Open speed sensor or harness.

Service circuit 519 or 523 (open)

Both are the VSS circuits, VSS to RABS module.

 

 

I checked for power at the speed sensor and there is none, where you think I should start now? Where does the power for the sensor come from? Thnx

 

A few days ago I bought a used 1992 F-250. Everything was fine after driving about 50 miles, until the tires locked up and I slid through a stop light (during the damned snow we just had). Lo and behold the RABS light turned on along with the check engine light. I located two separate black wires with orange stripes underneath the glove box (neither were connected to anything). I tried grounding both wires several different ways but had no luck with the RABS light blinking (just glowed solid). Hoping someone can help. I will try to post a photo of the wires.

i have this issue to. The light was on. So i looked under the dash. The orange and black connector was unplugged. I didn't know if it was supposed to be since it's a diagnostic connector. So i grounded it and with the ignition on and engine off it went off. When i started the engine the light came on and it blinked three times. Then it blinked a 9 times. So if it is supposed to be connected where would it connect? I'm going to shoot the wires and make sure they are all good and clean the sensor for good measure. Thanks.

 

This thread is almost three years old bud

 

well hopefully it didn't take them 3 years to resolve the issue and they can help me out lol I didn't actually notice that but maybe bumping it to the top will catch everyone's eye again

 

Maybe so, but I don't think any of these guys are still active on here.
