Diagnosing Customer Concerns With Hard Fault Codes

Most Safety Restraint System (SRS) diagnostic procedures will require the use of the system deactivation and system reactivation procedures. These procedures require the removal of the driver side air bag module and disconnection of the passenger side air bag module, there by removing the risk of air bag deployment while diagnostics are performed.










Air Bag Simulators are required to perform diagnosis and testing of the air bag system. The air bag simulator is a 2-ohm resistor used to simulate air bag module connections to the System. It is not acceptable to short-circuit the air bag module connections with a zero-ohm jumper wire. If a zero-ohm jumper wire is used to short-circuit the air bag module connections, a Diagnostic Trouble Code (DTC) will be displayed.
