To-Orc Squib
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 nor ground) as protection against inadvertent deployment. Use of the Supplemental Restraints System (SRS) Load Tool Kit (special tool #8443A, SRS Load Tool) in the tests below substitutes a suspect squib with a known good component. The SRS Load Tool Adapter provides a test point as well as a method for opening the shorting bar connections within the ORC harness connector.
WHEN MONITORED
With the ignition on.
SET CONDITION
The Occupant Restraint Controller (ORC) monitors the resistance of the Driver Seat Belt Tensioner circuits. The ORC will set this DTC if it detects low resistance on the Driver Seat Belt Tensioner circuits.
