Driver Seatbelt Retractor Pretensioner Deployment Control Circuit Short To Ground
Driver Seatbelt Retractor Pretensioner Deployment Control Circuit Short To Ground
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 load tool in the tests below substitutes a suspect squib with a known good component. The use of jumpers and the ORC connector adapter tool provides a test point as well as a method for opening the shorting bar connections within the harness connector.
