INTEGRATION RELAYA

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 relay and the current flowing through the warning light flows from TERMINAL 9 of the relay to TERMINAL 10 to
GROUND, causing the warning light to light up. A buckle SW off signal is input to TERMINAL 8 of the relay to TERMINAL 10
to 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 1 of the relay flows from TERMINAL 10 to GROUND and the seat belt warning buzzer sounds for
approx. 6 seconds. However, if the seat belt is put on during this period (While the buzzer is sounding), signal input to
TERMINAL 8 of the relay stops and the current flow from TERMINAL 1 of the relay to TERMINAL 10 to GROUND is cut,
causing the buzzer to stop.
2. KEY REMINDER SYSTEM
With the ignition key inserted in the key cylinder (Unlock warning 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 integration relay, the relay operates, current flows from
TERMINAL 1 of the relay to TERMINAL 10 to GROUND and key reminder buzzer sounds.
