I can recall a few similar incidents, some time ago, reported by members of this forum. The culprit(s) turned out to be moths trapped inside the car, setting off the internal motion detector.

You can disable this detector when locking the car, by pressing the lock button three times in rapid succession while the alarm warning light is still flashing rapidly. All explained in the Owner's Handbook.

Co-incidentally, I recently had a similar problem, but no new occurrences.

I have checked there is nothing in my car I have disarmed it by pressing fob 3 times but I would still like to no what the codes mean and how to sort the issue out I don’t want to forget to disarm it and go off during the night

The "codes" you have seen, only provide confirmation that your alarm was triggered.

To obtain more details, you need a good diagnostic, such as DiagFCA or AlfaOBD and a copy of the Workshop Manual. The latter lists about 60 Diagnostic Trouble Codes (DTCs) which could be relevant, together with their possible causes and remedies. It might just be something simple, such as low battery volts or a poor ground connection somewhere.

many thanks for getting back
so if i get the workshop manual it will tell me what the fault codes are the i might find from a diagnosic machine

If you scan for DTCs using one of the diagnostic programs I mentioned previously, then any stored DTCs should be revealed. You can then get a description of the code from the workshop manual. I managed to download a copy of the manual via the LX forum several years ago, but there are also other websites which can provide manuals.

However, having identified a DTC, the manual will probably describe a test routine which involves additional test equipment which only a dealer will have, so the manual is not written for the benefit of a DIY mechanic.

In my experience, faults with the VTA are unusual, but it may be worth trying a search for previous posts on this topic.

Perhaps you could ask a Jeep/Fiat dealer to do a diagnostic, as they will have all the necessary gear.

BTW, when you disabled the interior motion sensor, did that solve the problem? If so, you may have already identified the culprit module.
