Default Pass-Key® Help

Ok, so I've traced my no-start to an CCM code 53, Pass-Key® - Key Detection Circuit Open or Shorted to B+. Now my question is, and the FSM doesn't tell me, is what the hell does that mean? How the hell am I suppose to figure out which wire that is? Thanks.

Looks like the new Ignition Lock Cylinder is bad too. Going to try to switch that out tonight or tomorrow and see what happens. Great, I've got to pay for another key to be cut. Gotta love chinese parts...

The CCM is not seeing a circuit on the wiring ( Key Detection Circuit) that goes to the contacts in the ign switch that read the key resistor.
There is a 2 wire connector on the underside of column you can unplug ( check FSM for colors ) and put a DVM on the switch side of the connector to see if you can read the resistor pellet .If you can see the resistor when you turn the key on then problem is with wiring from connector to CCM

IT IS ALIVE. I'm 90% sure it was the starter solenoid. I put in the old key cylinder and VAROOM, she roared to life. Now, back out to put her all back together (took out the seat and center console to get to stuff). Now if I could only get my money back from getting the key made.
