Passenger Frontal Squib 1 Control Wires Shorted Together
Description
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 in the tests below substitutes a suspect squib with a known good component. The use of the Adapter, Supplemental Restraint System Load Tool provides a test point as well as a method for opening the shorting bar connections within the harness connector.
