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 driver side air bag modules from the vehicle, removing the risk of air bag deployment while diagnostics are performed.






Two of the Rotunda Air Bag Simulators 105-R0009 or equivalent is required to perform diagnostics and testing of the supplemental air bag restraint system. The air bag simulator is a 1-ohm resistor that must be used to simulate an air bag connection in the system. It is not acceptable to jump the air bag connection 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.
