Cadillac Repair: 1995 caddy deville, theft security, change oil

Question
96000 miles today the display read "traction disabled" and wouldnt start then i waited and tried again started kind of erractic then leveled out but now is reading "theft security problem/car may not restart" "check coolant" "check washer fluid" "change oil" "traction disabled" "service engine" and when I apply the break the lights on the display flash and the ABS symbol blinks. Could this be just an alternator or a censor or something?

Answer
The FIRST thing I would do is have the charging system tested. Once it is verified that it is OK, You need to be mechanicaly inclined or know of someone who is, You will need a DIGITAL MULTIMETER, Simple electrical schematics, Test procedures and picture locations of the components within the systems that are 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.
