Seat Belt Buckle Switch: Description and Operation
Operation
OPERATION
The seat belt switch is designed to control a path to ground for the seat belt switch sense input of the ElectroMechanical Instrument Cluster (EMIC) (also
known as the Cab Compartment Node/CCN). When the driver side front seat belt tip-half is inserted into the seat belt buckle, the switch closes the path
to ground; and, when the driver side front seat belt tip-half is removed from the seat belt buckle, the switch opens the ground path. The switch is actuated
by the latch mechanism within the seat belt buckle.
The seat belt switch is connected in series between ground and the seat belt switch sense input of the instrument cluster. The seat belt switch receives
ground at all times through its pigtail wire connection to the seat wire harness from a take out of the body wire harness. An eyelet terminal connector on
the body wire harness ground take out is secured beneath a ground screw on the left cowl side inner panel, beneath the instrument panel.
The seat belt switch as well as the hard wired inputs and outputs of the switch may be diagnosed using conventional diagnostic tools and procedures.
Refer to the appropriate wiring information.
