Master siren communication fault
Summary of the thread
A 2021 Renault Master with an electric engine is experiencing a 'siren communication fault' error, leading to a non-functional alarm system. The initial suspicion is a cable or plug issue. Checking the alarm fuse is suggested as a potential simple fix, but if that doesn't resolve the issue, a wiring problem with the siren itself might be the cause, necessitating professional repair.

I haven't checked the fuses yet, I was planning on doing that next. Did the fuse fix it for you, or was it something else?

Unfortunately not, I took it to a shop. It turned out to be a wiring issue with the siren itself. If checking the fuses doesn't work, I'd suggest taking it to someone. Mine was throwing errors too.

Thanks for the info. I've checked the fuse and it's not that. I will book it in with a mechanic. They quoted me 95€ for the repair which sounds reasonable.

Yeah, I had a similar issue with my 2018 Opel Corsa. Alarm was acting up. Have you checked the alarm fuse? Might be a simple fix.
