RAV4 4-Door 4WD L4-2.0L (3S-FE) (1997)
Key Reminder Switch: 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, 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 LH 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. KEY REMINDER SYSTEM
With 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 key reminder buzzer sounds.
