Standby Power Supply: Service and Repair

The electrical circuit necessary for system deployment is powered directly from battery and back-up power supply. To avoid accidental deployment and possible personal injury, the airbag system must be deactivated prior to repairing or replacing any system components.

Fasteners used on airbag components must be replaced after removal. The fasteners are coated with an epoxy adhesive making them non-reusable.
