Inflatable Curtains
XC90
Never use an ohmmeter or similar tool to test airbags, inflatable curtains, the adaptive steering column or seat belt tensioners. Disconnect airbags, inflatable curtains, the adaptive steering column or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.
Depending on the model and configuration, there are up to four inflatable curtains connected to the supplemental restraint system module (SRS). Their connectors are electrically separated from each other.
For the 7 seater XC90 models, the inflatable curtains are in the roof between the A and D-posts. For the 5 seater XC90 models and other models, the inflatable curtains are in the roof between the A and C-posts.
The configuration is as follows:
- On the 7 seater XC90, side and rear inflatable curtains on each side. There are a total of four inflatable curtains
- On the 5 seater XC90 and other models, there is one inflatable curtain on each side. There are a total of two inflatable curtains.
The inflatable curtains have only one ignition component each. The task of the 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 inflatable curtains on the side where the collision occurred.
The inflatable curtain uses a pyrotechnic component in combination with a reservoir which stores a gas. On activation the pyrotechnic charge and mixes with the stored gas. The gas mixture is blown into the inflatable curtain which falls and covers the side windows and B post. If rear inflatable curtains are installed the C post is also covered.
Where there are two inflatable curtains per side, these are always activated simultaneously.
Never use an ohmmeter or similar tool to test airbags, inflatable curtains, the adaptive steering column or seat belt tensioners. Disconnect airbags, inflatable curtains, the adaptive steering column or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.
