My abs light came on and when I restarted the truck it wasn't on any idea what that could mean?

 

There's probably something wrong with your ABS system if I had to guess. Go to O'Reilly Auto Parts and get the code read so you can figure out exactly what it is and how you can fix it.

 

the abs light went off after I turned the truck off

 

Like I said, I'd take it somewhere they have a code reader and get the code read, then you could find out what the light means.

 

There will be a soft code stored.

 

I removed the ABS sensor from the hubs on my '01 4x4, cleaned the sensors and re-installed them. Light went out and stayed out for a week or two and came back on. Heard on a truck show on TV that can be a sign that the unit bearing (or hub assembly) seal is leaking grease past it and the assembly needs to be replaced. Haven't done it yet.
