Corolla LE Sedan L4-1.8L (1ZZ-FE) (1999)
System Outline
The current is applied at all times to TERMINAL (A) 3 of the integration relay through the DOME fuse.
1. SEAT BELT WARNING SYSTEM
When the ignition SW is turned ON and the driver's seat belt is not used, the current flows from the GAUGE fuse to the integration relay at the
same time, the current flows to TERMINAL 9 of the relay from the GAUGE fuse through TERMINAL (A) 9 of the integration relay to
TERMINAL (D) 2 of the seat belt warning light. This current activates the integration relay and, at intervals of approx. 0.6 seconds, current
flowing through the warning light flows from TERMINAL (A) 2 of the relay to TERMINAL 7 to GROUND, causing the warning light to blink.
