Peugeot 206 Siren Communication Fault

I had a similar issue with my 206. Does the error message specifically mention anything about the alarm system controller or a defective cable?

Yes, the error log suggests a defective cable or plug connection of the component. Did you manage to fix the error yourself?

Yes, that sounds exactly like what happened to mine. Given the complexity and potential for further issues, I ended up taking it to a workshop. It's probably the best course of action.

Thanks for the help. I took it to a workshop as you suggested, and it turned out to be a faulty connection. They replaced the connector, and everything is working fine now. The repair cost was 95€.
