Caution: Refer to SIR Caution in the Preface section.
Caution: Do not strike or jolt the inflatable restraint sensing and diagnostic module (SDM). Before applying power to the SDM, make sure that it is securely fastened with the arrow facing toward the front of the vehicle. Failure to observe the correct installation procedure could cause SIR deployment, personal injury, or unnecessary SIR system repairs.
Important: The following repair procedures should only be used in the event that the inflatable restraint SDM mounting studs and/or fasteners are damaged to the extent that the SDM may no longer be properly mounted.

10.2. | Drill out the weld spots to the weld stud from the floor pan side, then remove and discard the stud. |
10.3. | Condition the floor panel attaching surface where the new stud is to be installed. |
10.4. | Install new weld stud GM P/N 115115602 and clamp the weld stud. |
10.5. | Migweld the stud at the drilled holes from above or below the floor pan, as required. |
