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. System Deactivation ProceduresThese procedures allow the removal of the air bags from the vehicle thereby removing the risk of air bag deployment while diagnostics are performed.






Rotunda Air Bag Simulator 105-00010 or equivalent is required to perform diagnosis and testing of the air bag system. The air bag simulator is a 2 ohm resistor used to simulate an air bag connection to the system. It is not acceptable to jump out the air bag connection with a zero ohm jumper wire. If a zero ohm jumper wire is used to jumper out the air bag connection, a system fault may be displayed (Diagnostic Trouble Code 34 or 35) according to the priority scheme.

NOTE: The air bag simulator 105-00010 for 1993 vehicles has a different connector than previous simulators. The new simulator will only mate with 1993 vehicles and beyond. Likewise, the old simulator 105-00008 will only mate with 1992 and previous model year vehicles.
