WARNING:

Never use an ohmmeter or similar tool to test airbags, door mounted inflatable curtains, adaptive seat belt tensioners, the adaptive steering column, rollover bar cassette or seat belt tensioners. Disconnect airbags, door mounted inflatable curtains, adaptive seat belt tensioners, adaptive steering column, rollover bar cassette or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.

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

The door mounted inflatable curtains are positioned in the upper section of the left and right doors. They have only one ignition component each. The task of the door mounted inflatable curtains is to protect the head and the upper body in the event of a side impact. The Supplemental restraint system module (SRS) activates the door mounted inflatable curtains on the side of the impact.

The door mounted inflatable curtain uses a pyrotechnic component in combination with a reservoir which stores a gas. On activation the pyrotechnic charge combusts and mixes with the stored gas. The gas mixture is blown into the door mounted inflatable curtain, which inflates and covers the side windows.

WARNING:

Never use an ohmmeter or similar tool to test airbags, door mounted inflatable curtains, adaptive seat belt tensioners, the adaptive steering column, rollover bar cassette or seat belt tensioners. Disconnect airbags, door mounted inflatable curtains, adaptive seat belt tensioners, adaptive steering column, rollover bar cassette or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.
