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 module (connected to neither power nor ground) as protection against inadvertent deployment. Use of the SRS Load Tool 8443A in the tests below substitutes a suspect squib with a known good component. The use of the SRS Load Tool Adapter provides a test point as well as a method for opening the shorting bar connections within the harness connector. When Monitored: The ORC sends out a 40 ma diagnostic current on each squib voltage supply circuit at power up and every 500 ms thereafter while the ignition is on. Set Condition: This Diagnostic Trouble Code (DTC) sets when the ORC detects an open or high resistance on the squib circuit for more than 2.5 seconds. This DTC transitions from active to stored when the ORC sees a recovery from an open condition for greater than 2.5 seconds.
