Theory Of Operation

WARNING: This page is about a different car, the 2019 RAM 3500 HD and 2019 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

When powered, the Occupant Restraint Controller (ORC) sends a test current to the Impact/Pressure Sensor circuits. During this test, the sensors discovered are checked for agreement with the pre-programmed configuration of components assigned to the module.
