So, back to my original question, I have a 2005 Crossfire Roadster with 28000 miles on it and runs great. I changed the RCM last year when the car wouldn't start. Everything is working on the car except the Computer module under the dashboard, it isn't reading any fail codes. Does the RCM control the computer module under the dashboard to let you know what the code is for inspection failing. Thanks for any help!
