Installing the test device
Install the test devices to the connectors for the cables instead of the airbags. The test devices are used so that no diagnostic trouble codes (DTCs) are registered when the engine is started.
On model 1999-2004, 1 or 2 9511506 alternatively 9511506 version B are used depending on the version the connectors have.
On certain versions of model year 2005 or later, 2 9511506 or 9511506 version B is used for the green and violet connector. Use 9511506 version B for the gray connector that is found on certain vehicles.
Install the battery negative lead, see Battery, disconnecting
