Theory of Operation

WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The Occupant Restraint Controller (ORC) receives power for the Run/Start circuit from the Totally Integrated Power Module (TIPM) via fuse M16. This circuits power the ORC and the capacitors used to initiate the squib deployment circuits in the event of collision detection. The use of the Supplemental Restraints System (SRS) Load Tool Adapter in the tests below provides a test point in place of the ORC harness connectors.
