RAV4 4WD L4-2.0L (3S-FE) (1996)
Seat Belt Reminder Lamp: Description and Operation
Current always flows to TERMINAL 1 of the Integration Relay through the DOME fuse.
1. SEAT BELT WARNING SYSTEM
When the Ignition SW is turned ON, the current flows from the GAUGE fuse, to TERMINAL 7 of the Integration Relay. At the same time,
current flows to TERMINAL 9 of the relay from the GAUGE fuse through the seat belt warning light. This current activates the integration relay
and the current flowing through the warning light flows from TERMINAL 9 of the relay --> TERMINAL 10 --> GROUND, causing the warning
light to light up. A buckle SW OFF signal is input to TERMINAL 8 of the relay, the current flowing to TERMINAL 7 of the relay flows from
TERMINAL 10 --> GROUND and the seat belt warning buzzer sounds for approx. 4-8 seconds. However, if the seat belt is put on during this
period (while the buzzer is sounding), signal input to TERMINAL 8 of relay stops and the current flow from TERMINAL 7 of the relay -->
TERMINAL 10 --> GROUND is cut, causing the buzzer to stop. .
2. UNLOCK WARNING SYSTEM
When the Ignition key inserted in the key cylinder (Unlock SW ON), the ignition SW still OFF and driver's door open (door courtesy SW ON),
when a signal is input to TERMINAL 6 of the relay, the integration relay operates, current flows from TERMINAL 7 of the relay -->
TERMINAL 10 --> GROUND and unlock warning buzzer sounds.
