The other day the park brake light and anti-lock light showed up on the truck and are both staying illuminated. both park brake and brakes work fine and as they should. I had a fuse blow for the turn signals and both these dash lights run off that fuse BUT the turn signals work fine? is it a bad sensor maybe? any help greatly appreciated, thanks.

 

Checked the brake fluid level?

 

I`ll go check that. that never even crossed my mind, thanks

 

Did you make sure the parking brake lever is returning all the way to the top?

 

yes I had that problem last year and put a new spring in it to keep it where it should be. that wouldn't affect the anti lock light though

 

Check the abs connector on the very top of the diff. Housing. My lights were on, went to unplug that said connector and whole assembly broke off in my hand. So I just unplugged the abs unit behind the glove box. Lights are out. For my use of the truck the abs is non sense. But if you want to retain the abs, id look at that sensor. Known to corrode, and be very careful, at it's age it might do what mine did.
