Evalia Alarm Failure

My 2013 Nissan Evalia with an electric engine has an alarm system that's stopped working at 238k km. The error memory shows a siren communication fault. I suspect a bad cable or plug. Has anyone else experienced this?

Summary of the thread

A 2013 Nissan Evalia owner reported an alarm system failure, with an error indicating a siren communication fault, suspecting a bad cable or plug. Another Evalia owner suggested checking the wiring harness near the siren for moisture or corrosion, which can cause signal issues. The problem was resolved by replacing a corroded connector at a local shop, restoring the alarm's functionality.

I own an Evalia too and recall something similar. Have you checked the wiring harness near the siren? Moisture or corrosion can cause signal problems. Are there any warning lights, or just the alarm?

No warning lights, just the silent alarm. Where is this wiring harness located? Is it easy to access, or will I need to dismantle half the car?

I remember now, I had the same symptoms. After a lot of fiddling, it turned out to be a faulty connection. I'd suggest a workshop. It cost me 95€ to fix. They can diagnose it and replace the cable or plug if needed.

Thanks for the advice. I took it to a local shop, and you were right. It was a corroded connector. 90€ total, and the alarm is working again.
