Mission Weld Nut, Restraints Control Module (RCM) and Side Impact Sensor
WELD NUT REPAIR - MISSING WELD NUT, RESTRAINTS CONTROL MODULE (RCM) AND SIDE IMPACT SENSORNOTE: 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.
1. Depower the system See SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING.
2. Obtain a 6 mm (0.24 in) weld nut.
3. Obtain a 6 mm (0.24 in) grounding screw.
4. Route a sufficient length of copper welding wire through the weld nut clearance hole and back out an adjacent access hole.
5. Feed the copper welding wire through the weld nut then through a standard flatwasher.
6. Secure the flatwasher so that it cannot be pulled off the end of the copper welding wire.
7. Pull the copper welding wire back through the clearance hole, allowing the weld nut and flatwasher to follow the copper welding wire through.
8. 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.
9. Holding the weld nut securely in place and using a MIG welder, weld in four places around the edge of the weld nut.
10. Metal finish as required.
11. Verify the nut is securely in place.
12. Install the crash sensor.
13. Tighten the attaching screws to specification. See Torque Specifications.
