Output Test

Important Note: Please do NOT run Output Tests (function 03) on your Airbag Controller!
No, it won't deploy your airbags. But it MAY render the vehicle undrivable. Running Output Tests is supposed to make the airbag controller generate a simulated crash signal to the rest of the systems in the vehicle so that unlocks itself and shuts various things OFF. Unfortunately, one of the things it shuts off in the Touareg is the power supply to the Engine Control Module. Two things are needed (confirmed by a dealer tech who was brave enough to run Output Tests on an Airbag Module):

  1. Clear "Crash Data" code from the DTC Screen in 25 - Immobilizer.
  2. Reset the yellow Circuit breaker under driver's seat. The circuit breaker should be yellow and should be visible/accessible if you remove the carpeted "step" trim panel at the front of the seat (an operation requiring some dexterity, but no tools).

Beginning with Beta 310.0, VAG-COM will pop up a warning if you try to run Output Tests on the Airbag Controller.
