I did find this on disabling the seat belt chime:
From the off position:
- Turn Key to ON
- Within 6 seconds, press and HOLD the odometer button
- Wait 12-14 seconds (count 1 one-thousand, 2 one-thousand.....)
- Buckle your seat belt
- Let go of the odometer button and press it again
- Wait a few seconds until it clears and goes back to the odometer with your mileage displayed.
or you can try this sequence. I think it is outlined in the manual somewhere.- Press the ODO/TRIP switch until odometer displays "ODO"
- Turn the ignition switch "Off"
- Turn the ignition switch "On"
- Press ODO/TRIP switch immediately (within 6 seconds after turning the power switch on) and hold it down for 10 seconds or more
- Continue holding the ODO/TRIP switch and fasten the Passengers seat belt
- Check that the odometer displays either "b-on" or "b-off" (it will be "b-on")
- Press the ODO/TRIP button to change the display to "b-off"
- Turn the ignition switch off.
- Turn the ignition switch on while depressing the brake pedal.
- Check that no seat belt chime sounds when setting in the front passenger seat.
I am planning on trying these steps this weekend to see if they work. I would try the spring removal, but I really don't want to tamper with something that is supposed to save my life in the event of an accident. I will let ya'll know if this worked or not.
