Problem with Power Seat Belt
Hi, it's Armando,

I have another problem with the power seat belt - light on the dash panel appear to stay light on. When car is running? What might be the problem?

Thank you

RE: Problem with Power Seat Belt
Here are a few things to look at. First the description of operation.
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. At the same time as the warning light blinks, a seat belt retractor SW OFF signal is input to TERMINAL (A) 5 of the relay, the current flowing to TERMINAL (A) 3 of the relay flows from TERMINAL 7 to GROUND and the seat belt warning buzzer goes on for approx. 6 seconds . However, if the seat belt is put on during this period (while the buzzer is sounding and warning light blinking), signal input to TERMINAL (A) 5 of the relay stops, and the current flow from TERMINAL (A) 3 of the relay to TERMINAL 7 to GROUND is cut, stopping the buzzer and warning light blinking.
2. KEY REMINDER SYSTEM
With the ignition key inserted in the key cylinder (Unlock warning SW ON ), the ignition SW still OFF and the driver's door open (Door courtesy SW ON ), when a signal is input to TERMINALS (A) 4 and 8 of the relay, the integration relay operates, the current flows from TERMINAL (A) 3 of the relay to TERMINAL 7 to GROUND and the key reminder buzzer goes ON .


I would first suspect the switch that is attached to the seatbelt retractor assm. See picture below.
