Seat Belt Control Module: Description and Operation

Seatbelt Control Timer Module (SCTM) Location:

This vehicle uses a convertible structural seatbelt system. Anchors hold the belt to the seat rather than the body. Embodied in the belt system is a Retractor-Integrated Height Adjuster. The purpose of the height Adjuster is to accommodate a wide range of occupant sizes.

The SCTM is mounted near the center of the vehicle. A G-sensor is located inside the module.

This belt system attaches to a reclinable seat back so the traditional locking pendulum mechanism would not provide security. A solenoid was designed to lock the belt and was made part of each of the retractor mechanisms to each seat back. An impact sensor deactivates the solenoids. The impact sensor is a component of the Seatbelt Control Timer Module (SCTM) located under the center console.

The G-sensor is sensitive to frontal impact and to a roll or pitch or more than 45 degrees and to acceleration or deceleration equal to or greater than 0.7G in any direction.
