Seat Belt Latch: Description and Operation
DESCRIPTION
Vehicles equipped with the structural seat system have an electric seat belt retractor latch solenoid that is integral to each of the two outboard front
seat belt retractors. These solenoids are grounded at all times through their wire harness connector and circuit. These solenoids receive battery
current that is switched by the Seatbelt Control Timer Module (SCTM), through a fuse in the junction block.
The electric seat belt retractor latch solenoids can- not be adjusted or repaired. If the solenoid is faulty or damaged, the entire driver side or
passenger side seat belt retractor unit must be replaced.
OPERATION
When the electric seat belt retractor latch solenoids are energized, the retractor spools are unlatched which enables the seat belt webbing to be
withdrawn from the retractor. When the solenoids are de-energized, the retractor spools are latched which prevents the seat belt webbing from
being withdrawn any further from the retractor.
