What is a Dodge Grand Caravan 4th Gen airbag control module?

The Dodge Grand Caravan 4th Gen airbag control unit, also known as the Occupant Restraint Module (ORM), is the central safety unit.

This critical module is responsible for the precise analysis of crash information and the correct activation of passive safety systems. It plays a crucial role in the drivability and safety of your Dodge Grand Caravan.

Proper operation is essential because a faulty control module can activate the airbag warning light and prevent deployment in an emergency, requiring immediate Dodge Grand Caravan 4th Gen airbag control module repair.
