abs and parking brake light on
 

Last week i got home from a 28 day run on the drills, so i fired up my truck and the abs light and the parking brake light was on, they were not on when i left to go drilling and as far as i know nobody used my truck while i was gone. Any idea whats causing those codes to pop up?

Sounds like you'll either need to find a good shop or have access to a good scan tool.

Check the wires at the rear diff my 03 did that and the wires had broken there

There is a sensor on the rear diff and one on the right front wheel. The one on the rear is the most common to give problems but start there first. I've dealt with this bs too.

it could be anywhere. get a good scanner on it and it will tell you where the problem is. could be a rat has chewed on the wires
