Passive restraints are safety systems designed to protect vehicle occupants during a crash without them having to buckle or activate anything manually. The most common examples are airbags and automatic seat belts (popular in older vehicles). These systems work in tandem with active restraints like standard manual seat belts to manage the kinetic energy of a human body during a sudden deceleration.
The diagnostic tool is showing high resistance in the driver side passive restraint circuit, probably a bad clock spring.
