Theory Of Operation

WARNING: This page is about a different car, the 2016 RAM 1500. 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 or ground) as protection against inadvertent deployment.

SPECIAL TOOLS: 

(special tool #8443A, SRS Load Tool)

The use of the SRS Load Tool Adapter (#8443-8 jumper, SRS Load) provides a test point, as well as a method for opening the shorting bar connections within the harness connector.
