Red brake warning light and ABS light and 4X4 inactive light are constantly on

Hello, I'm Danny.

This means you have codes stored in your vehicles computer relating to the brakes and ABS- anti lock brake system. The first thing you need to do is access the stored codes. If you don't have access to a scanner or code reader most auto parts stores have a tool loaner program and can rent you one. Auto parts stores like AutoZone can check codes for free. Just be sure the scanner has anti lock brake system capability. Here is a tutorial showing what is involved checking codes:

Once you perform this get back to us with the code information and we can then properly diagnose these issues. Hope this helps and thanks for using 2CarPros.
