Driver Knee Bolster Squib Control Circuit Open
Driver Knee Bolster Squib Control Circuit Open
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. The knee blocker airbags are concealed below the lower edge of the instrument panel, just beneath the steering column opening cover on the driver side or just beneath the glove box door on the passenger side.
