Hello everyone!

I can place it either behind the steering wheel or maybe below it. Does anyone know specifically where the really is and even better, how to get to it?

Thanks!

 

​​​​​​Hello @notwise ,
There is no relay for the seat belt chime, I think you are referring to the speaker (chime) itself, the speaker is located inside the speedo instrument cluster..
You can not remove the speaker as it also gives the sounds for other functions, such as turn signal tone.

I assume that you are trying to stop the chime from sounding, if so, you would do coding of the J285 instrument cluster itself to stop the seat belt warning.

That’s really helpful. I’m actually thinking of what it would be cool to replace the quite pedestrian electronic tone with something more suitable.

So, I wonder what tones this speaker is responsible for..

Turn signal
Lights
Seat belt

What else?

 

Hello @notwise ,
I am not sure on how you plan on changing any tones, as the speaker is just that, a speaker, the speaker itself only sounds the tone that is fed to it by the circuitry of the Instrument cluster board.

Ok - the warning chime is on the CAN-bus. I’m going to see how to find it’s address.

My plan is to be able to listen for the CAN messages for ‘lights on’ ‘turn signal’ and ‘seat belt’, etc and then play my own sounds through my own setup. If I can do that, I’ll unplug the small speaker in the instrument cluster.

I bought a parts-only cluster for a phaeton and disassembled it - should be pretty straightforward.

I’m using a CAN sniffer for arduino - should be a nice application for it.

 

@notwise ,

Please be sure to share that gem if it works !

It would be to have a special voice message for the seat belt, or that you left your lights on... 🤣

Sounds like my home automation system

It makes sense, really - the whole system communicates via a twisted pair network. When you push the horn button, for instance, the horn controller sends a message out to the whole network, with the horn actuator being the only one that ‘responds’ to the message. The brake light ecu, for example, just ignores it.

So, my plan is to first just connect to the obd port and listen for traffic. If I can isolate/replicate the unique codes when the turn signals are requested, etc etc, then I can program the arduino to hit the little sample sound player I have - it has usb and 8meg of ram to upload mp3s.

So - what do you guys think the sound *should* be? The hope is to be able to substitute any sound for the seat chime, lights on, and turn signals.

 

Oh I totally agree. It should be 'comparatively easy' to intercept the CANBUS command, and use that as a trigger to issue a totally different command....

I'm trying to think of what the chime *should* be but struggling. Bear in mind that my Home Automation system is programmed to say things like 'I'm shutting down the power' and 'Sonic deadline is up' so I *may* not be the best arbiter....

Right now, I’m leaning towards Big Ben for the seat belt chime, Westminster for headlights!

 

Someone just showed me a great video from South Africa, a team of carjackers was tugging the driver's door open, next thing all you hear are loud gunshots, lots of gunfire, the carjackers scattered. It was just his horn, he had set the horn up to sound like a gunfight and…it worked marvelously when he needed it to.

 

Love it! The best one I’ve seen recently was the guy at a gas station:

Justice served!

 

Hi, my speaker died on the board. Does anyone know where I can find the board to replace the speaker? I'm having problems location the actual board.
Thanks!
