i'm still trying to hunt down the cause of my abs and brake light.... i replaced the rear sensor but still no luck..... i have a new front sensor but can't see where it goes...anyone know where to start looking?? or know anything else it could be???

 

Watch your speedometer from 0 to 25 and see if it is working properly. If it isn't it's the speed sensor located on the top of your differential. Even if you have already replaced the sensor you might have got a bad one from the dealer. As far as I know the only things that will cause both of those lights to come on at the same time are that speed sensor or a bad abs unit. Good luck.

 

hello,

I had the same problem on my ram.

reason was a damaged wire from the brake very dispenser (i hope thats the correct translation) .
i repaired that wire and everything's ok now

hope to be useful

Just had my wheel speed sensor replaced a week ago. (less actually) No more abs / brake light. I agree with mrfixit, maybe you got a bad replacement part. my two cents.
