Seat Belt Warning relay

[MeteorMetal86]

Hi,

for a ROW/Euro '86 Targa I'm wondering if I have the right seat belt warning relay... the issue I have is the seat belt warning light is always on.

I have checked the wiring and when belt is clicked there is continuity between pin 86 and G on the relay mount (or was it the other way around, I forget now! either way, wiring seems right). So far so good but the relay when I turn it over, has no pin on the G-position... does anyone know if my relay is somehow modified? It is the correct p/n as far as I can tell. Also pin 85 seems to have been broken off... I guess this is the door buzzer someone has disabled? That I can definitely live with, but the seat belt warning light is kindof an annoyance :-)

Thanks in advance,
Mike

What's the story of your car? Is it right hand drive ? Reason I'm asking is because according to PET, the relay you are showing is said to be for countries that drive on the wrong side of the road. For other countries, including US, Canada and Saudi Arabia, it should be 911 618 102 00. That's what is in the PET.
Also, since your car is a Euro, it shouldn't have this relay at all nor the related buzzer. On Euro cars, this relay was simply replaced by two jumpers on the socket, because the seat belt warning function was just the standard indicator light on the dash.

Ok, that's interesting. The car has German origins and is a LHD. I have papers dating it to being sold there.

Weird. Mine is also originally from Germany and LHD. It has the two jumpers as shown on the factory diagram.

Let me go check if the seat belt insertion breaks the circuit or closes it. If it breaks it, then the light goes out if I bridge L and G and 86 and 31. Easy check... give me a few hours.

EDIT - I just went out and indeed inserting the seatbelt breaks the circuit. I'll make some jumpers tomorrow and that should close the case. I wonder why there is a relay there though... who would put something like that in? hm. oh well, onwards...

That pic (also in my shop manual) has the wrong positions for the device, at least on my 88. Mine was in the middle of that little “platform” in the frunk, not on the LH side. It was also ’sideways’ in the sense that the part # info was 90 degrees off, pointing to the other side of the car. (not sure if that is normal or even consistent car to car)

Learned from a PCA Q&A post that if the lights stay on it’s your door switches, and sure enough both of mine were wonky. I could have cleaned them I guess but I just replaced them. I also pulled the control unit and used contact cleaner & an old toothbrush on the pins. Now it’s all happy again.

Here is what it looks like on my ROW 88. Looks like same as in the workshop manual.

Thanks, that is precisely how I solved it. Not a ”neat” engineering solution but that’s how they did it I guess.
