Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Buckle TENSIONER
A seat belt buckle tensioner supplements the dual front airbags for domestic market versions of this vehicle. This tensioner is integral to the front seat belt buckle unit, which is secured by a large screw to the outside of the inboard seat cushion frame of the front seat. The buckle tensioner consists primarily of a buckle (1), a molded plastic scabbard, a cable and piston, a cable guide and bracket, a metal cylinder tube and a small pyrotechnically activated gas generator (4).
The buckle tensioner is controlled by the Occupant Restraint Controller (ORC) and is connected to the vehicle electrical system through a dedicated take out of the seat wire harness by a keyed and latching yellow molded plastic connector insulator to ensure a secure connection. The buckle tensioner has a single pigtail harness (3) for the integral seat belt switch.
The buckle tensioner cannot be repaired and, if ineffective or damaged, the entire front seat belt buckle unit must be replaced. If the front airbags have been deployed, the buckle tensioners have also been deployed. The buckle tensioners are not intended for reuse and must be replaced following any front airbag deployment.
