Diagnosing Customer Concerns With Hard Fault Codes

Most air bag Supplemental Restraint System (SRS) diagnostic procedures will require the use of the deactivation and reactivation procedures. Arming and Disarming These procedures require the removal of the driver air bag module and disconnection of the passenger air bag module, thereby removing the risk of air bag deployment while diagnostics are performed.

Air Bag Simulator T96P-50-AH:

Special Tools

Air bag simulators are required to perform diagnosis and testing of the SRS. 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 Lamp Fault Code (LFC) will be displayed.
