whenever i turn my turck on the ABS and BRAKE lights come on and stay on while the truck is running. wondering if anyone has ever had this problem, the brakes arent acting funny. i also have a superchips programmer and i checked the codes and nothing is coming up with it. help!

 

Have ya checked to make sure you have enough brake fluid?

Fairly simply, but it'll cause the lights to come on.

 

speed sensor on the top of the rear diff is going bad. next your speedo will start acting funny

 

Go to rockauto.com and you can get that abs speed sensor for 30 bucks. It takes about 5 minutes to replace and no more abs light. As far as the brake light I'd take to Checker auto parts and have them hook it up to their computer and that will solve that.

 

I had this on mine i have a 99 its is your rear speed sensor. once that is replaced the lights will be off and if your speedometer is actin wierd it will be fixed. my speedometer didnt move till i reached about 27 mph

 

Hey,

I am having the same problem. I have a 98 1500 4x4 5.9L.

Brake & ABS light came on and at the same time the speedometer won't work until @25 mph. Where is the speed sensor located? How hard a fix is it? Autozone does not list that part in their inventory. Does it have another name?

Thanks for the info.
James
