I replaced the rear sensor on the rearend and the light remains lit. What else can i check whats left to check its only rear abs. Is there any sensors on the brakes themselves??. The rear brakes are OEM with 136,000 on them but they look good. Fluid level is good contacts are good going into the abs unit under the master cylinder. I am now baffled any help would be a plus here.

 

I would follow the wire back. Check for any shorts, and tight connections. I read of the wire hitting an exhaust pipe once after the truck had an especially heavy load.

 

The problem has been fixed. It was the brake reservoir (low fluid switch) switch had some corrosion on it. I simply detached it cleaned the contacts and plugged it back in and NO LIGHT.

 

Thanxs for the followup.

 

Neighbor had same problem with light being on and all i did was add just a bit od brake fluid and wala no more light!!!!!.
