First you need to download the 2005 service manual from the archives, it has most of the DTCs
What I get is:
B1040- NO CAN COMMUNICATIONS WITH YAW RATE/ACCELERATION SENSOR
P1174 - STEERING ANGLE SENSOR NOT INITIALIZED
P1175 - STEERING ANGLE SENSOR MOMENTARILY NOT INITIALIZED
P2300 - Ignition Coil 'A' Primary Control Circuit Low


Do not think any of these would keep it from starting but the RCM or SKREEM could.
