Both the break light and antilock break light are lighting up on the message center. The break fluid is very dirty, Im in the process of changing out the master cylinder, removing the old fluid and replace with new. Would that make both lights turn off?? or is there another problem with the abs??? Also where is the abs computer located on this truck???

Thanks,

You could have a bad sensor on the top of the rear axle or the connector on it may be loose or corroded.

 

I have a bad abs term. conition so when it rains or somehow when water can splash on it it will do the same. so it might be something like that for you. or just shorting together. inspect the wire from the top of the axle all the way to the computer if you can

 

Yep...here's some more info...

the link provided just takes me back to the same page.

So the axle in your schematic is the rear correct??? Also, where is the(rawl) computer unit located???

 

Sorry,I corrected the link above.
The picture is of the rear axle. The RWAL module should be on the passenger side under the dash.



The control module is located behind the lower right side cowl panel of the passenger compartment.

 

Ok im really confused, for the rawl do you mean under the glove box and behind that black plastic wall
picture of what area im talking about:
