I have an '03 350, TPMS never worked so when I got new tires I had them rebuild them and reset the TPMS system. but these pictures are of the read out that I get. shouldnt it show both front tires and both rear tires? If can add a picture of how they should look and how can I get them all reading correctly?

 

It looks just like yours but with numbers in the bottom also, where your dashes are.

 

Your rear sensors are either dead, broken, or not reset correctly. Being an 03 your sensors are probably dead. They're battery powered and need to be replaced entirely once they're dead (Battery might be changeable, but I'm not sure). I have an 06 and my rear sensor's battery is dead so it shows the dashes like yours.
