Two problems on my 05 6.0 2wd The abs light cam on and cant figure it out, i try and run the codes and it tells me there are none. Also The tow haul light started flashing while driving the other day and the trans temp gauge stoped working, im guessing its the sending unit for the temp. is this correct? Any input would be great..

 

A normal code reader wont read brake codes, you need a specific reader for that. Your problem is quite common though. Take the sensor out of the rear diff, it sits right on top, try cleaning it up and see if it fixes it, if not, just get a new one. As for the trans temp gauge, I'm not too sure on.
