My abs light stays on constantly

 

And have you had anything looked at?

 

Could be anything.... Do you have any specifics or something?

 

The truck is acting completely normal

 

Mine did that once, was a sensor on the back axle.

 

What ate the symptoms of it

 

Go get it read. Mine has been on the past couple months, acts normal except no cruise control, it is a Rear Isolation Inlet Valve Circuit Malfunction. Here is a tip from a post I read; follow the brake lines from the master cylinder to a block that houses the abs module and hydraulic control module. Disconnect the connector here and visually look at connector pins, clean as necessary, then reconnect to see if problem goes away. Leave disconnected for a half hour or so. If still a problem, you will need a scanner capable of reading abs codes, unfortunately with 4 wheel abs no way to check "flash codes" or jump wires that I know of.

I need to try this myself!

 

Autozone won't read it

 

No other auto stores near you? I would just try cleaning the connector and see if that helps and then go from there if you cant read it.

 

Yea there's a few more were would read it
