Seat Belt Reminder Buzzer: Description and Operation
Current Always flows to TERMINAL 1 of the Integration Relay through 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
Current flowing through the Warning light flow 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 through
TERMINAL 10 --> GROUND and the Seat Belt warning Buzzer sound for Approx. 4-8 Seconds. However, if the 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
With the Ignition Key Inserted in the Key Cylinder (Unlock SW ON), the Ignition SW still OFF and Driver's Door opens (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.
