COMPONENT SERVICE-METERS AND GAUGES
SEAT BELT WARNING SYSTEM
1. If the driver turns the ignition key to “ON” while his seat
belt is unbuckled, the seat belt warning system is acti-
vated to provide an audible and visual reminder through a
buzzer and light to fasten the seat belt properly.
2. The seat belt warning system consists of a belt switch,
buzzer, warning light, belt warning timer.
Seat Belt Warning Timer
The timer operates when the ignition key is in the “ON”
position and terminals 2 and 3 are electrically connected to
terminal 4 (ground). (16W73 1)
Seat Belt Warning Light and Buzzer -
When the seat belt switch is ON (seat belts not buckled) with
the ignition key at the ON position, the seat belt warning
timer causes the seat belt warning light to illuminate and the
buzzer to sound for 4 to 8 seconds. If the seat belt switch is
set to OFF (the seat belts buckled) during theseat belt wam-
ing timer interval, only the buzzer is cancelled.
Seat Belt Switch
CONTINUITY TEST
1. Pull back the floor mat and disconnect th.e seat belt
switch connector from where it is at the attachment to
the buckle stalk assembly.
2. Use an ohmmeter to check for a short circuit at the 0.3-Y
wire and the 0.3-RB wire of the, driver’s seat belt switch.
(16W732)
3. If the ohmmeter reads no resistance with the buckle
unlocked and indicates an open circuit when the buckle is
locked, the belt switch is operating properly.
4. If a microswitch is defective, the buckle stalk assembly
containing microswitch should be replaced. For replace-
ment, see GROUP 23.
