SEAT BELT SWITCH
DESCRIPTION
The seat belt switch is a small, normally open, sin-
gle pole, single throw, plunger actuated, momentary
switch. Only one seat belt switch is installed in the
vehicle, and it is integral to the driver seat belt
retractor assembly. The seat belt switch is connected
to the vehicle electrical system through a short pig-
tail wire to a dedicated take out and connector of the
body wire harness.
The seat belt switch cannot be adjusted or repaired
and, if faulty or damaged, the entire driver seat belt
and retractor unit must be replaced.
OPERATION
The seat belt switch is designed to control a path
to ground for the seat belt switch sense input of the
Electro-Mechanical Instrument Cluster (EMIC). The
seat belt switch plunger is actuated by the seat belt
webbing wound onto the seat belt retractor spool.
When the seat belt tip-half webbing is pulled out of
the retractor far enough to engage the seat belt buck-
le-half, the switch plunger is extended and closes the
seat belt switch sense circuit to ground; and, when
the seat belt tip-half webbing is wound onto the
retractor the switch plunger is depressed, opening
the ground path. The EMIC monitors the seat belt
switch status, then controls the seatbelt indicator
and sends electronic chime request messages over
the Programmable Communications Interface (PCI)
data bus to the Central Timer Module (CTM) based
upon that input.
The seat belt switch receives ground through its
pigtail wire connection to the body wire harness from
another take out of the body wire harness. An eyelet
terminal connector on that ground take out is
secured under a ground screw to the left lower B-pil-
lar. The seat belt switch is connected in series
between ground and the seat belt switch sense input
of the EMIC.
DIAGNOSIS AND TESTING - SEAT BELT
