Cadillac Repair: 94 Cadillac Deville code question, rear wheel speed, code faults

Question
Hi there;
I've read some of your question/answers and I can tell you know what you're talking about when it comes to Cadillacs so I wanted to ask you about a friend's '94 Deville that I have been working on.
Here's my question; 1.  I did the off/warmer button diagnostic and here's exactly what I got, in the order that it displays:  PO52 HIST, IO39 CURRENT, IO52 HIST, NO ACP CODES, NO SIR CODES, TO37 CURRENT, PCM?.  That is exactly as is displays in the same order.  It's different than what my Chilton's manual (which I don't trust to much) says it should be.  Can you tell me what those codes are for?  
2.  Is there a way to turn off the ANTI-LOCK light(which also turns off the traction control) because I had her brakes apart and forgot and turned the key on and set a code or tripped that light.  
Again, thanks for your knowledge and help.  Guys like you are a huge blessing to us do-it-yourselfers!

Answer
P052 = battery was disconnected sometime in the past.

I039 = (4.6L engine) = Loss of ROAD SENSING SUSPENSION
                      (RSS) DATA.

I039 = (4.9L engine) = SPEED SENSITIVE SUSPENSION SIGNAL
                      FAULT.

T037 = Left Rear wheel speed sensor continuity fault.

In order to turn off the anti-lock light you must fix the code faults. I can provide you with all the pictures and diagnostic procedures which are NUMEROUS so that you can diagnose and fix the vehicle depending upon your mechanical ability. E-mail me at: onlineautohelp@msn.com.
