had a few pulls on the dyno a couple weeks ago and realized the ABS INOP light came on. It has never came on before so i thought it might be something they did on the dyno. went back and talked to the guys but found out they didnt do anything to cause that. Any ideas whats wrong or troubleshooting to do? Its a mostly street car so i would like to keep ABS.

UPDATE
ive been looking under, and all around the rear end and all the wires are connected, nothing is missing or pulled out. I cant seem to find a picture of where the wheel speed sensors are located. can anyone describe where they are or have a pic of them?

 

afternoon bump

I read a thread a while back where the light stayed on. I think in that case they banged the wiring harness by the rear axle when they were strapping the car down.

 

i read this thread but the dyno day i went to was february 11th and the light is still on. however they did say my car was the most complicated to strap down so maybe they did hit the harness or something.

 

Here is that thread:

If you have a 4 ch abs system your rear abs sensors will be located on your brake bracket below each axle. Its held into place by a single 10mm bolt. If you have a 3 ch abs system you only have one abs sensor and that is located above the rear end.

Hope this helps

 

you could get it scanned at any local parts store that has an ABS code scaner...
