Seat Belt Latch: Description and Operation
SYSTEM OPERATION
A seat belt retractor latch solenoid is integral to each of the two outboard front seat belt retractors. The solenoid is grounded at all times through its
wire harness connector and circuit. The solenoid receives battery current, which is switched by the Seatbelt Control Timer Module (SCTM),
through a fuse in the junction block.
When the seat belt retractor latch solenoids are energized the retractor spools are unlatched, and the seat belt webbing can be withdrawn from the
retractor. When the solenoids are de-energized the retractor spools latch, preventing the seat belt webbing from being withdrawn any further from
the retractor.
The seat belt retractor latch solenoids cannot be repaired. If the solenoid is faulty or damaged, the entire seat belt retractor unit must be replaced.
