WARNING:

Never use an ohmmeter or similar tool to test airbags, inflatable curtains adaptive belt force limiters, adaptive steering column or belt tensioners. Disconnect airbags, inflatable curtains, adaptive belt force limiters, adaptive steering column or belt tensioners before testing them. Failure to do so may result in accidental deployment, which in turn could result in serious injury or death.

When the impact protection in the adaptive steering column is deployed, a pin is triggered that makes the steering column more deformable. In the event of a severe impact, it will possible to press the steering wheel toward the dashboard to a greater degree than if the steering column were rigid.

Steering is not affected by the deployment of the pin. The pin is deployed by a pyrotechnical charge and is located in the center of the steering column. The impact protection system in the adaptive steering column only deploys if the driver is wearing the seat belt and when the airbag is deployed. The entire steering column must be replaced if the impact protection system in the adaptive steering column has deployed.
