Retractor TENSIONER
Seat belt retractor tensioners supplement the dual front airbag system for all versions of this vehicle. These tensioners are integral to the front seat belt retractors (1), which are secured near the base of the inner B-pillar on the right and left sides of the vehicle. The retractor is concealed beneath the molded plastic inner B-pillar trim. The retractor tensioners are controlled by the Occupant Restraint Controller (ORC). Each retractor tensioner has an initiator connected to the vehicle electrical system through a dedicated take out of the body wire harness by a keyed and latching yellow molded plastic connector insulator (2) to ensure a secure connection.
An adaptive load-limiting device is also integral to the front seat belt retractor to supplement the anchor and retractor tensioners. The adaptive load limiter is also controlled by the ORC. Each adaptive load limiter initiator is connected to the vehicle electrical system through a dedicated take out of the body wire harness by a keyed and latching yellow molded plastic connector insulator (3) to ensure a secure connection.
The retractor tensioners and adaptive load limiters cannot be repaired and, if ineffective or damaged, the entire front seat belt and retractor must be replaced. If the front airbags have been deployed, the retractor tensioners and adaptive load limiters have also been deployed. The retractor tensioners and adaptive load limiters are not intended for reuse and must be replaced following any front airbag deployment. A growling or grinding sound while attempting to operate the seat belt retractor is a sure indication that the retractor tensioner and adaptive load limiter have been deployed and require replacement. Refer to RETRACTOR, SEAT BELT, REMOVAL . If a front airbag has deployed, for a complete summary of items that need to be replaced or inspected. Refer to STANDARD PROCEDURE .
