TECH 2 Scan Tool

J-41433 SRS Driver/Passenger Load Tool
The SRS Driver/Passenger Load Tool J-41433 is used only when called for in this section. It is used as a diagnostic aid and safety device to prevent inadvertent air bag assembly deployment.

The load tool has four yellow connectors attached to its case.

The three small connectors are electrically functional and serve as resistive load substitutions.

No more than two connectors are used at any time. One of the small connectors is used to substitute for the load of the driver air bag assembly when it is connected at the top of the column to the SRS coil assembly. Another small connector is used to substitute for the load of the driver air bag assembly and the SRS coil assembly when it is connected at the base of the column to the SRS wiring harness. The third small connector is used to substitute for the load of the passenger air bag assembly when connected to the passenger air bag assembly harness connector.

By substituting the resistance of the load tool when called for, a determination can be made as to whether an inflator circuit component is causing system malfunction and which component is causing the malfunction. The load tool should be used only when specifically called for in the diagnostic procedures.




J-39200 DVM
The J-39200 DVM is the preferred DVM for use in SRS diagnosis and repair. However, J-34029-A may be used if J-39200 is not available. No other DVMs are approved for SRS diagnosis and repair.




Scan Tool
The Tech 2 is used to read and clear SRS Diagnostic Trouble Codes (DTCs). Refer to the Tech 2 Operator's Manual for specific information on how to use the Tech 2.




J-35616-A Connector Test Adapter Kit
The J-35616-A Connector Test Adapter Kit must be used whenever a diagnostic procedure requests checking or probing a terminal. Using the appropriate adapter will ensure that no damage to the terminal will occur from the DVM prove, such as spreading or bending. The adapter will also give an idea of whether contact tension is sufficient, helping to find an open or intermittent open due to poor terminal contact.




J-42986 SRS Deployment Tool
The J-42986 SRS Deployment Tool must be used for deployment of the undeployed air bag.




J-42987 SRS Adapter For Load Tool
The J-42987 SRS Adapter be used for connect previous load tool to new SRS system when inspect SRS system harness.




J-41497 SRS Deployment Fixture
