I have a ton of them man, and I'm not mechanically inclined at all. Here is a list of codes I am getting. 

B1161, b1162, b1252, b125, b1220, b127, b1660, b1910, b1982, b1983, b2107, b2115, b2119, b2120, b2150, b2750. 

C1210, c1216

U1016, u1064, u1088, u1096, u1300, u1275, u2150. 

Any help will be greatly appreciated.

Cross-ref here for 98 but similar: 

 

Quite a few yes.  Is there a specific symptom that you also are finding?

The B codes are body short circuits (windows, seats, memory settings); the C codes chassis (suspension, stabilitrak), the U codes are bus communication issues.  Good new is no P codes for engine issues. 

Several of these seem to suggest the system is shorted to ground, which may mean water incursion, or frayed wiring, or poor ground -- such as lost ground strap(s)?

What is your compaint? Besides codes?

How strong is the battery?  Has it been load tested?  Are connections at the battery good and clean?

Typically lots of codes are battery related. 

Interesting there are no P codes, lots of network and B or Body codes.  C is Chassis

You can start by removing the key from the keychain and use the key without a lot of weight hanging off of it.  Or, the key resistor may be dirty or worn.  If so, you can solve the problem by cleaning the resistor contacts or, at worst, with a new key.

Sometimes this problem is caused by the contacts for the resistor wearing out within the steering wheel mechanism.  That's a significant repair problem.  I would try a new key first.

There is a link to a spreadsheet with OBD codes and lots of other information about the 1997 model year Cadillacs.

Very likely the wires that run from the ignition down the column have broken.

Try moving the tilt column to a different position and see if it works.

The wires run down under the dash above the accelerator.

I just find out the resistance of the pellet and install a pellet resistor inline under the dash, therefore bypassing the Vats system
