Cadillac Repair: 96 deville, test procedures, traction control

Question
I have codes pc0300 and pc0507. What are they and is it something I can handle myself? Also, codes tc0061 and rs0062. Service ride control, traction control, and abs are on. Which of these codes relate to which ones or all?
Thanks for your help.

You will need, If necessary, Electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture.  I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
