For 1990-2009 cars

#### J 38715-A SIR Driver/Passenger Load Tool

Use the J 38715-A SIR Driver/Passenger Load Tool only when the SIR diagnostics require this tool. Use the load tool as a diagnostic aid. Use the tool also as a safety device in order to prevent inadvertent deployment of the inflator module.

The load tool has four yellow connectors which are attached to the case. The three small connectors function electrically. These connectors serve as resistive load substitutions. The large dummy connector does not serve as a load substitution. This connector is not used.

Use no more than two connectors at any time. One of the small connectors with adapter J 38715-15 is used in order to substitute the load of the inflatable restraint steering wheel module. This connector is at the top of the column to the inflatable restraint steering wheel module coil. Another small connector with the adapter J 38715-25 substitutes the load of the inflatable restraint steering wheel module and of the inflatable restraint steering wheel module coil. This connector is attached at the base of the column to the SIR wiring harness. The third small connector with adapter J 38715-20 is used in order to substitute for the load of the inflatable restraint IP module. This connector is attached to the harness connector of the inflatable restraint IP module.

You substitute the resistance of the inflator module in order to determine if an inflator circuit component is causing a system malfunction. Use the load tool only when the diagnostic procedures require the load tool.

#### J 38715-96 SIR Shorting Bar Tool

Use the J 38715-96 SIR shorting bar tool only when the SIR diagnostics call for this tool. The shorting bar tool lifts one side of the shorting bar on the harness connector of the Sensing and Diagnostic Module (SDM). The Connector Position Assurance (CPA) lifts the opposite side of the shorting bar. If the CPA and the shorting bar tool are installed, the warning lamp circuit disconnects from the ground circuit. This turns the warning lamp to the OFF position.

#### J 39200 DMM

The J 39200 is the preferred DMM for SIR diagnosis and for repair. However, you may use the J 34029-A if J 39200 is not available. Other DMMs are not approved for SIR diagnosis and for repair.

#### Scan Tool

Use the Scan Tool for the following reasons:

• | Reading and clearing SIR system diagnostic trouble codes (DTCs)

• | Providing SIR system circuit values using the data list function

Refer to the Scan Tool Operator's Manual for specific information on how to use the scan tool.

You may also use scan tools from other manufacturers. For specific instructions, refer to the Operator's Manual for the tool.

#### J 35616-A Connector Test Adapter Kit

Use the J 35616 Connector Test Adapter Kit when a diagnostic procedure requests that you check, or probe a terminal. If you use the appropriate adapter, damage will not occur to the terminal from the DMM probe, such as spreading or such as bending. You can use the adapter for the following:

• | Indicate if contact tension is sufficient

• | Find an open, or an intermittent open, because of poor terminal contact
