Diagnosing Customer Concerns With Hard Fault Codes

Most air bag system diagnostic procedures will require the use of the system deactivation and system reactivation procedures. These procedures allow the removal of the air bags from the vehicle, removing the risk of air bag deployment while diagnostics are performed.





The Rotunda Air Bag Simulator is required to perform diagnosis and testing of the air bag system. The air bag simulator is a resistor that must be used to simulate an air bag connection in the system as specified in the deactivation procedure. It is not acceptable to jump the air bag connections with a zero ohm jumper wire. If a zero ohm jumper wire is used, a system fault may be displayed according to the priority scheme.
