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.

When powered, the Occupant Restraint Controller (ORC) sends a test current to the squibs to verify the integrity of the squib and wiring. These circuits are maintained in a "floating" configuration at the ORC (connected to neither power nor ground) as protection against inadvertent deployment. Use of the Supplemental Restraints System (SRS) Load Tool Kit (special tool #8443A, SRS Load Tool) in the tests below substitutes a suspect squib with a known good component. The SRS Load Tool Adapter provides a test point as well as a method for opening the shorting bar connections within the ORC harness connector.
