Tacoma 2WD V6-3.4L (5VZ-FE) (1995)
Seat Belt Reminder Buzzer: Description and Operation
System Outline
Current always flows to TERMINAL 12 of the integration Relay through the Dome fuse.
1. SEAT BELT WARNING SYSTEM
When the Ignition SW is Turned ON, current flows from the Gaugefuse to TERMINAL 6 of the integration Relay. At the same time, current
flows to TERMINAL-A 2 of the Relay from the Gauge fuse through the Seat Belt Warning Light [Comb. Meter]. This current activates the
integration Relay and, for Approx. 4-5 Seconds, current flowing through the warning Light flows from TERMINAL-A 2 of the Relay -->
TERMINAL 7 --> Ground, causing the warning Light to Light up. At the same time as the warning Light Light up, a buckle SW ON signal is
input to TERMINAL-A 3 of Relay, the current flowing from TERMINAL 12 of the Relay flows to TERMINAL 7 --> Ground and the Seat
Belt Warning Buzzer Sound for Approx. 4-8 Seconds. However, if the Seat Belt is put ON (Buckle SW OFF) during this period (While The
Buzzer Is Sounding), signal input to TERMINAL-A 3 of Relay Stops and the current flow from TERMINAL 12 of the Relay --> TERMINAL 7
--> Ground is cut, causing the Buzzer to stop.
2. UNLOCK WARNING SYSTEM
With the Ignition Key inserted in the key Cylinder (Unlock SW ON), the Ignition SW still OFF and front LH Door open (Door Courtesy SW ON
), when a signal is input to TERMINAL-A 10 of the Relay, the Integration Relay operates, current flows from TERMINAL-A 5 of the Relay -->
TERMINAL 7 --> Ground and the Unlock Warning Buzzer Sounds.
