How should you service an air bag supplemental restraint system (SRS) to ensure safety and proper repair on 2004 Mercury Mountaineer?

All technicians working on vehicles with air bag supplemental restraint systems (SRS) should use safety glasses because this protects them from injuries that could result from accidental deployments. The safety canopy module deployment requires an assessment of damaged tether cord rivet nuts prior to putting in a new safety canopy. Start the procedure by making the system powerless followed by removing the trim panel from the A-pillar. The next step involves removing the bracket and bolt from the A-pillar which allows secure storage of the side air curtain tether cord assembly along with bracket outside the work area. Attach the proper service tool to sand the rivet nut shoulder until the external material layers vanish then utilize it to make an opening in the remaining rivet nut through the rivet nut hole. Always substitute the rivet nut using original Ford Motor Company parts identified through the Ford Master Parts Catalog while selecting the precise square shank rivet nut and placing it within the rivet nut hole for the specific vehicle. Insert the rivet nut through its hole by using an appropriate rivet nut installation tool. Position the A-pillar tether cord near the bolt antichannel and tighten it according to the specified torque value. Before putting back the A-pillar trim panel make sure the tether cord is in its proper placement.
