Use the J 35616-A Connector Test Adapter Kit whenever a diagnostic procedure requests testing or probing a terminal. Using the appropriate adapter will ensure that no damage to the terminal occurs from the DMM probe, such as spreading or bending. The adapter will also give an idea of whether contact tension is sufficient. This helps to find an open or intermittent open due to poor terminal contact.

Use the J 38125-B Terminal Repair Kit for SIR wiring repair. This kit contains a special crimping tool, heat torch, and sealed splices. Do not use the terminals in the kit in order to replace damaged SIR system terminals unless specifically indicated by the terminal package.

Use the J 38715-A SIR Driver/Passenger Load Tool only when the SIR diagnostics call for use. The Load Tool is used as a diagnostic aid and a safety device in order to prevent inadvertent inflator module deployment.

The load tool has 4 yellow connectors attached to the case. The 3 small connectors are electrically functional and serve as resistive load substitutions. The large dummy connector does not serve as a load substitution and is not used. Do not use more than 2 connectors at any time.

One of the small connectors is used in order to substitute the load of the inflatable restraint steering wheel module. The connector is connected at the top of the column to the inflatable restraint steering wheel module coil. Use 1 of the following adapters in order to connect the load tool to the steering wheel module coil:

A second small connector is used in order to substitute the load of the inflatable restraint steering wheel module and the inflatable restraint steering wheel module coil. The second small connector is connected at the base of the column to the SIR wiring harness. The third small connector is used to substitute for the load of the inflatable restraint IP module. The third small connector is connected to the inflatable restraint IP module harness connector.

Substitute the resistance of the inflator module in order to determine whether an inflator circuit component is causing a system malfunction. Use the load tool only when specifically called for in the diagnostic procedures.

Use the J 38715-96 SIR Shorting Bar Tool only when the SIR diagnostics call for use. The shorting bar tool lifts one side of the shorting bar on the inflatable restraint sensing and diagnostic module (SDM) harness connector. The connector position assurance (CPA) lifts the opposite side of the shorting bar. When the CPA and the shorting bar tool are installed, the warning lamp circuit is disconnected from the ground circuit turning the warning lamp OFF.

Use the J 38826 SIR Deployment Harness in order to deploy a driver inflator module outside of the vehicle. Use 1 of the following adapters in order to connect the deployment harness to the inflator module:

The J 39200 Digital Multimeter (DMM) is the preferred DMM for use in SIR diagnosis and repair. The J 34029-A may be used if the J 39200 is not available. No other DMMs are approved for SIR diagnosis and repair.

Use the J 39401-B SIR Deployment Fixture when deploying passenger frontal air bags, side impact air bags, or seat belt pretensioners outside of the vehicle. Use the deployment fixture in order to secure the module for deployment.

Use the scan tool for the following reasons:

Refer to the scan tool operator's manual for specific information on how to use the scan tool.
