SEATBELT WARNING LIGHT

Postby XJ40-MARK » Wed Oct 02, 2013 7:21 pm

guys ;)

red sovereign.
when i first got this car, i noticed that the seat belt warning light was flickering on/off most of the time, but was off more than it was on. however, now it dos`nt come on at all.
am i right in assuming, that its the seatbelt buckle stalk at fault and what are they like to change?
and given mine is the magnolia trim, can i buy ANY stalk and swap over the trim thats on them?

I believe the stalks are the same and the covers do come off.

Its most likely to be the seat sensor itself in the cusion these. Ive seen this a few times before. Not saying its not the buckle though.

From my experience the buckle covers cannot be changed, well easily anyway. Better of spray painting one the correct colour.

Yes, agree, I would check the pressure sensor built into the cushion. Probably a break in the wire. Check for continuity with your multimetre.
Get some pix, as I have never really looked at then in detail, so not sure on repairing then.

Does the fault go when you plug both belts in?

If it does stop the fault then it is probably the seat sensor in the passenger seat or the connectors and wires to it.

If it does not stop the fault when you plug both belts in then it is probably the switch in the drivers stalk or the connectors and wiring to that.

The wires and connectors to both these can easily become damaged when work is done on the car involving the removal of one or both seats for example.

I have also known the seat structures to brake on the 40’s at the welding joints and this can trap the wires and damage them as well.

Taking the seats apart and putting them back together again is not that difficult. In fact it is a lot easier on the 40’s than in many other cars.

In the past few years I have removed the cover from the seat back to sew in new piping and stripped the seat base down to weld it up. There are no special tools or 'tricks' involved but like many jobs on the 40 it just takes time.

I am sure if I can do it anyone can.

The only problem parts I had were the chrome bezels for the head rest support holes that tend to snap.

However I suppose you could always by-pass the stalk and seat base switches, or even just remove the warning bulb from the dashboard if you just want the light to go out and do not want to do a proper job of fixing the fault!

Does the fault go when you plug both belts in?


theres no fault there to come or go, its not there period!
when i switch the ignition on and all the lights go out, normally, the light that remains on, if you are`nt wearing your seatbelt, is the warning light.
when i first got the car, it was `on`, but flickering on and off all the time, even with the buckle in the stalk. now, it dos`nt do anything. dos`nt come on, go off, flicker, anything, it just dos`nt come on at all now.

i did`nt know the seats had sensors in them.
i want it to work right, but not so sure i fancy taking the seat apart.

It is an easy job mark, only two screws on the front of the squab. When you lift the squab up you can see the wires going to the sensor which is under a plastic cover glued to the foam on the under side of the seat iirc.

Very easy, even I can do it! 8-)
