The Intoxilyzer 5000 has had numerous issues over the years. However, the government always falls back on the position that the machine runs a self diagnostic check to ensure that it is working properly. This is fine if the self diagnostic test actually works. Dr. Stephen Rose and Charles Smith, International Forensic Research Institute located at Florida International University ran various diagnostic tests on the Intoxilyzeer 5000 with key parts disconnected. They found that the machine does not ahave the ability to recognize when key parts are disconnected and still showed the diagnostic test to be OK. Some of these key parts were vital to ensure that outside interferents would not affect the test.
