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 seat belt 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.

There are two inflatable curtains connected to the supplemental restraint system module (SRS). Their connectors are electrically separated from each other.

The inflatable curtains are located in the roof between the A-post and C-post. They have only one igniter component each. The purpose of the curtain is to protect the head and parts of the upper body in the event of a side-on collision. The supplemental restraint system module (SRS) deploys the inflatable curtain on the side closest to the point of impact.

The inflatable curtain uses a pyrotechnic component in combination with a reservoir which stores a gas. In the event of deployment, the pyrotechnic charge combusts and mixes with the stored gas. The gas mixture inflates the curtain, which falls down and covers the door windows and B-post.
