While driving around yesterday, I started up and pulled away in a rush. My ABS light started flashing intermittently, and while driving the speedometer would continually cycle from the current speed down to 0, then go back up to the current speed, and down again.
After having stopped at the next destination, when I started up again, it has not done it again since.
I am thinking it must be the ABS sensor on its way out. Or maybe worn disk pads?
It's your VSS speed sensor mounted on the rear differential. Look at the top of the rear pumpkin. A new one can be had for $25. About 5 minutes to replace and you're good to go.
The ABS flashing is the code you need, count the number of flashes and this is what is wrong with your system (start vehicle, light should go solid, then start flashing, and then stay solid). Do it two or three times to verify the number, then do a search for "ABS flashing 12 times" and you will figure this out.
I think I have some resolution. Yesterday I read somewhere that a bad earth on the driver side headlamp could cause the ABS light and the flashing O/D.
Interesting enough, I replaced my driverside head bulb about a week ago, because it went dim. Thought it was the bulb.
Then last night the new bulb went dim too, and I figured it can be a bad earth.
When I got home, I touched around on the headlamp harnass, looking for a bad connection.
So this morning when I started up, the ABS light and flashing O/D is gone, and the dim bulb is bright again.
This weekend I will look for, and try to correct the earth.
did you disconnect the batteries for about 20 minutes so the computer will reset to the new part?I had the same problem and someone else here staraightened me out with that advice.
How does the headlight earth affect the abs light? I think I may be having this problem also bacause my turn signals are not working either... I have a new vss to put in anyways but I dont think it is going to fix the problem.
My symtoms are abs light, no turn signals, no speedo which leads to flashing od light. Ill have to check my headlight to see if it is dim but I dont think it is...
