Weld Nut Repair - Missing Weld Nut, Restraints Control Module (RCM) And Side Impact Sensor
WARNING: This page is about a different car, the 2005 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- There are two procedures to repair a vehicle having missing air bag crash sensor attaching weld nut(s). Read both this procedure and WELD NUT REPAIR - "J" NUT, RESTRAINTS CONTROL MODULE (RCM) AND SIDE IMPACT SENSOR before proceeding with the repair.
NOTE:
- Use only this procedure if two or more weld nuts are missing, do not install the "J" nuts as outlined in Weld Nut Repair - "J" Nut, Restraints Control Module (RCM) and Side Crash Sensor.
NOTE:
- Radiator support repair shown, others are similar.
- Depower the system. See SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- Obtain a 6 mm (0.24 in) weld nut.
- Obtain a 6 mm (0.24 in) grounding screw.
- Route a sufficient length of copper welding wire through the weld nut clearance hole and back out an adjacent access hole.
- Feed the copper welding wire through the weld nut, then through a standard flatwasher.
- Secure the flatwasher so that it cannot be pulled off the end of the copper welding wire.
- Pull the copper welding wire back through the clearance hole, allowing the weld nut and flatwasher to follow the copper welding wire through.
- Position the weld nut to the weld nut clearance hole, firmly pulling on the copper welding wire allowing the secured flatwasher to hold the weld nut in position.
- Holding the weld nut securely in place and using a MIG welder, weld in four places around the edge of the weld nut.
- Metal finish as required.
- Verify the nut is securely in place.
- Install the crash sensor.
- Tighten the attaching screws to specification. See Torque Specifications.
