Nut, Side Air Bag Sensor
-
Warning
-
• To avoid accidental operation (deployment) of the air bag and possible personal injury, always deplete the back-up power supply before repairing or replacing any front or side air bag structural component, and before servicing, replacing, adjusting, or causing impact to components near the air bag sensors, such as doors, dashboard, console, door latches, strikers, seats and bonnet latches.
• Before servicing, refer to this workshop manual to determine the location of the crash zone sensor.
• The side air bag sensors are located at the base of the B pillar.
• To deplete the backup power supply, disconnect the battery negative cable and wait 1 min or more. Make sure to disconnect the auxiliary batteries and power supplies (if equipped).

Note
-
• There are two procedures to repair a vehicle with a missing crash zone sensor installation weld nut. Read the following procedure and “Weld Nut Repair-Missing Weld Nut, Side Air Bag Sensor” in this section before proceeding with the repairing.
• If two or more weld nuts are missing, do not install the nuts as outlined in this procedure. Weld nuts must be installed as outlined in “Weld Nut Repair-Missing Weld Nut, Side Air Bag Sensor.”
• The following procedure applies to vehicles that have a rectangular hole in the sheet metal that is in close proximity to the missing weld nut.
1. Obtain a nut.
2. Obtain a 6 mm {0.24 in} grounding screw or equivalent.
3. Install the nut through the rectangular hole in the sheet metal.
4. Install the side air bag sensor.
-
Note
-
• Verify that the threaded portion of the nut is aligned with the clearance hole in the sheet metal.
5. Tighten the installation screws to the specified torque.

• There are two procedures to repair a vehicle with missing side air bag sensor installation weld nut. Read both this procedure and “Weld Nut Repair-Nut, Side Air Bag Sensor” before proceeding with the repair.
• Use only this procedure if two or more weld nuts are missing, do not install the nuts as outlined in “Weld Nut Repair-Side Air Bag Sensor.”
• The figure shows repair of the radiator support. Repair of other parts is the same.
1. Obtain a 6 mm {0.24 in} weld nut
2. Obtain a 6 mm {0.24 in} grounding screw.
3. Route a sufficient length of copper welding wire through the weld nut clearance hole and back it out an adjacent access hole.
4. Feed the copper welding wire through the weld nut, then through a standard flatwasher.
5. Secure the flatwasher so that it cannot be pulled off the end of the copper welding wire.
6. Pull the copper welding wire back through the clearance hole, allowing the weld nut and flatwasher to follow the copper welding wire through.
7. 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.
8. Holding the weld nut securely in place and using a MIG welder, weld in four places around the edge of the weld nut.
9. Metal finish if necessary.
10. Verify the nut is securely in place.
11. Install the side air bag sensor.
12. Tighten the attaching screws to specified torque.

• To avoid accidental operation (deployment) of the air bag and possible personal injury, always deplete the back-up power supply before repairing or replacing any front or side air bag structural component, and before servicing, replacing, adjusting, or causing impact to components near the air bag sensors, such as doors, dashboard, console, door latches, strikers, seats and bonnet latches.
• Before servicing, refer to this workshop manual to determine the location of the crash zone sensor.
• The side air bag sensors are located at the base of the B pillar.
• To deplete the back-up power supply, disconnect the battery negative cable and wait for 1 min or more. Make sure to disconnect the auxiliary batteries and power supplies (if equipped).
1. Obtain an 8 mm {0.32 in} grounding screw.
2. Drill out the internal threads of the stripped-out weld nut to 7.37 mm {0.29 in} using a large size drill bit.
3. Position the air bag sensor to the vehicle.
4. Install the 8 mm {0.32 in} grounding screw into the drilled-out weld nut.
5. Install the remaining attaching screws.
6. Tighten the attaching screws to specified torque.
