Multi Alarm System Fault

My 2001 Nissan Multi with a gasoline engine is giving me fits. The alarm system is completely dead, and the error memory shows a siren communication fault. I've jiggled some wires, but no luck. Could it be a fuse? Anyone experienced this?

I had a similar issue with my Multi. It sounds like a wiring issue, possibly a defective cable or plug connection to the siren. Have you checked the alarm controller?

Alarm controller? Where exactly is that located, and is there an easy way to test it? I'm not super tech-savvy, so ELI5, please!

Yes, siren communication fault means the alarm controller is likely the issue. Honestly, it's probably best to take it to a workshop. The price will be around 95€. They can properly diagnose the fault detection and signal problem.

Thanks a bunch! I appreciate the insight. Took it to the shop, and you were spot on – dodgy wiring to the alarm controller. All fixed now!
