They built ceritifcation specials to pass tests. Which means the devices under test were not representative of mass produced examples. Specifically they flashed some custom ROM on a airbag computer so it auto-deploys at scheduled T+ time from the beginning of a test run. That's kind of a huge deal because we wouldn't know if airbag is going to deploy in real crashes. Other tampering includes ignoring requirement that crashes must also unlock front doors, reporting numbers from a note hidden in palm while the test is running instead of from gauges, so on and so forth.
