01/11/2022 Q: What should be noticed when you connect the inflator module to the adapter on the SIR deployment harness?
A:
On the steering wheel dual-stage inflator module both connectors must be attached to the deployment harness adapter. This will ensure that both stage 1 and stage 2 of the deployment loops are energized, regardless of the deployment state.

01/11/2022 Q: What's the removal procedure for the inflatable restraint side impact module wiring harness?
A:
The removal procedure is to disable the SIR system, remove of passenger or driver inflatable restraint side impact inflator module wiring harness uses the same procedure, and remove the inflatable restraint side impact inflator module from the seat, with the seat back cover in the open position of the inflatable restraint side, then remove the retaining clips that secure the side impact inflator module wiring harness to seat.

01/11/2022 Q: What should you be careful about when replacing the Supplemental Inflatable Restraint (SIR) sensing system?
A:
Proper operation of the Supplemental Inflatable Restraint (SIR) sensing system requires that any repairs to the vehicle structure return the vehicle structure to the original production configuration. Not properly repairing the vehicle structure could cause non-deployment of the airbag in a frontal collision or deployment of the airbag (s) for conditions less severe than intended.

01/11/2022 Q: Can I remove the center fastener from the side impact module inflator?
A:
No, you cannot. You should not remove the center fastener from the side impact module inflator. If the center fastener is removed this could cause the side airbag to deploy improperly, or unnecessary airbag system repairs.

01/11/2022 Q: What should be known about dual-stage deployments?
A:
Dual-stage deployments are only used in the steering wheel and IP inflator modules. If stage 1 was used to deploy a dual-stage inflator module, stage 2 may still be active. If disposal of a deployed or undeployed dual-stage module is required both deployment loops must be energized to deploy the airbag.
