Diagnostic Notes

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





The Rotunda Air Bag Simulator 105-00008 is required to perform diagnosis and testing of the air bag system. The air bag simulator is a 1 ohm 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 connection with a zero ohm jumper wire. If a zero ohm jumper wire is used, a system fault may be displayed (Diagnostic Trouble Code 34 or 35) according to the priority scheme.
