Viano alarm system fault

[cadmonkey123]

Hi. I have a problem with my 2007 Viano van. Trying to solve it myself before taking to a dealer / mechanic.

I've run diagnostics, which have thrown up these fault codes, which occur each time I use the vehicle. B10A5 - Alarm cannot be armed. B10E0 - No communication with battery operated horn component H3/1. B10A1 - communication fault with component B44 or B44/1 interior protection sensors short circuit test of cables. B10A0 - communication fault with component B44 or B44/1 interior protection sensors test cable for open circuit.

Also, the alarm does not sound / activate.

I've searched around online and had a look at the wiring to see if any loose connections around the SAM box in the engine bay.

Has anyone had anything similar? Any help would be greatly appreciated.

Regards

I'd probably guess that the alarm siren needs swapping as it's the control module as well. I've seen them where the spade connections to the alarm have really badly corroded & the wires have become compromised.. for the time it takes it's worth having a look at that imho
