    Fault criteria
   
  
  
   Upon ignition, the impact sensor carries out a self-test. If an internal fault is detected, the impact sensor sends a message to the control module and a DTC is set.
   
   
   
    System reaction to a fault
   
  
  
   The control module ignores all signals from the impact sensor as long as the fault is present.
