Constant seatbelt warning light/beep even when fastened

[Chasabi]

Morning chaps. Gave the interior a good clean yesterday, including moving the seats as far forward as possible to clean behind them. When I took her for a spin a few hours later my seatbelt warning light/beep continued after I had connected my seatbelt. After about a minute it stops.

I got the missus to get in the passenger seat and not put the seatbelt on. As soon as the warning started beeping she connected her seatbelt and the warning stopped. I think it's definitely the driver side buckle sensor. Anyone fixed this before? Is it easy?

Sounds more like the passenger presence sensor rather than the buckle.
I'd have a look underneath and see if there's a loose cable connection.

As above, my bet is the passenger occupancy sensor, it must think there is always a passenger. Try plugging passenger seatbelt in and it will stop the beeps!

[Chasabi]

No definitely not the passenger occupancy sensor. Tried plugging passenger belt in and it still beeps/flashes.

Did you kneel on the seats when cleaning, or apply any pressure an certain points as this has been known to damage the occupancy sensor.

I would agree with the others that it's the passenger one at fault. Don't believe there is one on the drivers side for obvious reason.

Use SSS software retro section and turn off beeps!!

There was a post earlier in the year similar to yours, see below.

Fixed it. There's a prong that sits inside the belt clasp housing. The prong connects to 2 wires and was hanging out of the clasp housing. I must have pulled it out when cleaning down the side of the seat. It goes through the rubber sheaf so I think I've tugged the wire when I've pushed the sheaf down!! [SMILING FACE WITH OPEN MOUTH]

Glad you've got it sorted

I too had a similar issue, seat belt warning going off but intermittantly....Fault traced to muppet in drivers seat putting steering lock on passenger seat instead of floor, ....bloody sensitive those occupancy sensors..
