Why is the ABS light not working on my Bronco?
I have a 1995 Bronco that I just bought and the speedometer doesnt work, the abs light is on, the overdrive light flashes and as a result the transmission is shifting very hard and basically when ever it wants to. Ive read that the VSS in the rear diff sometimes goes out so I replaced that and nothing (its the same).
What to do if your Speedo is not working?
Run it around to heat the engine up and shift thru all gears incl Reverse. Then turn off all accessories/lights, etc. Make sure A/C is off and transmission is in Park (automatic) or in Neutral for a Manual & release clutch. Do Key On Engine Off (KOEO) portion first.
How can I tell if my speedometer is working?
If it works normally, then the speedometer module is at least receiving a speed input signal and the wiring and sensor & tone ring can be assumed to be good. Any slight dents, chips, etc., in either the exciter ring or VSS will create needle waver. Measure air gap between the VSS and exciter ring. It should be 0.38-0.51mm (0.015-0.020″).
Why do I have so many double posts on my Speedo?
It is related to the speed sensor VSS if you replaced the sensor maybe the wiring or maybe the teeth on the tone rine in the diff are F-ed up. All of your reported problems are from there. Not sure why you have so many double posts?
Why is the ABS light on and the Speedo not working?
After a recent jump start my daughter’s 1993 C180 developed 2 problems. The ABS light stayed on and the speedo didn’t work. A search of the forums suggested resetting the car by disconnecting the battery but that didn’t work.

How does the speedometer work and transmission doesn’t shift?
Speedometer doesn’t work and transmission doesn’t shift gears. The speedometer stays at 0 all the time. When the transmission is in drive it won’t come out of 1st gear. Reverse works fine, and if I manually put the transmission in 1st or 2nd it works fine. 102 people found this helpful.
