The seat belts along with attachment components need authorized dealership inspections for proper functioning following collisions to check retractors, buckles, belt tension sensor (BTS), front seat belt buckle support assemblies (slide bar), seat belt shoulder belt height adjusters, and child seat tether bracket assemblies, and the automatic locking retractor (ALR) for child seats in passenger areas. A new seat belt assembly becomes mandatory whenever any safety device displays damage or nonfunctionality or fails during the Functional Tests procedure. When attaching areas are damaged or distorted the sheet metal needs restoration to its original state before professional installers put in new seat belt assemblies and attaching hardware to avoid crash-related severe injuries and deaths. The installation of new driver and front outboard passenger seat belt systems with their components of retractors, buckles, and height adjusters becomes necessary after any crash where pretensioners activated. The first step before installing new seat belts requires checking all attaching areas for damage along with measuring distortion; any damage must be repaired to restore the original metal shape before proceeding with the new belt installation. All functional tests must be conducted for the components within this process.
