I have an alarm going off on my xj350 03 it sounds like morse code it starts as soon as you turn the key in the ignition and continues when driving or stationary there are no messagages no lights and nothing showing on computer scan at jag service HELP its driving me nuts like water torture !!

 

Maybe you can record and post it up, but this is a strange one on me.

 

Thanks for your interest but not sure how would post as have tries several different ways and forum unable to post mp4 with sound ?? could email from cvcstudios@yahoo.co.uk

 

Many thanks for your interest in My Morse code alarm ( Close encounters of the Jag kind ) I had done all you suggested before and to no avail !! However having driven around for a week with unknown aliens trying to contact me with continuous Morse code signals IT JUST STOPPED and having done nothing perplexed or what all I can say is they must be out of range





Best Regards Dave

Well I assume it is not emanating from the speaker on the rear shelf which is used by the parking sensors.

The only other source AFIK is the "speaker" associated with the security system which is located in the dash. I am not sure exactly where but if you dismantle the dash you will be able to find it (because it is making a noise!).

When you find it use a sledgehammer sorry soldering iron to disconnect it or possibly cover it in foam.

A drastic possible solution I know and you may end up with a security system fault message

but better than the noise.

 

Now that I have listened to the sound it is something I have never heard before.

The point is where is it coming from?

Possibilities are:

Speakers

Dash

Parking sounder.

the only way to tackle this that I can think of at the moment is to start pulling fuses.

There is a list of fuses in the Owners handbook and I would suggest that you start

with the sound system fuse and see if the noise stops.

Pulling fuses may cause unintended but hopefully recoverable consequences

eg you may need the radio code.

If you can determine which of the above possibilities is transmitting the sound

that would help.

BTW Heated rear window can interfere with the radio reception but I assume you are not using

that at the moment.

 

Hi cvcstudios,

In the recording the sound seems very soft in volume. Is it truly soft/quiet, or is it as loud as, for example, the Park Assist alarms?

If the sound is loud, it may indicate a fault in the Park Assist system or some other warning system, but I would have thought a code would have been triggered if that were the case.

Meirion1's suggestion to start pulling fuses may be the least expensive way to narrow down the possibilities.

One thought that occurred to me while listening is that it might possibly be electromagnetic interference either from one of the digital communications networks in the vehicle or from your mobile phone. You might try leaving your phone away from the car to see if the sound goes away.

Also, I don't see that you've mentioned or anyone has asked, is the sound the same whether or not the radio/audio system is turned on?

Cheers,

Don
