01134 code - audible alarm

[Ravs88]

Hi all

 

Wonder if someone can shed some light, I've got the following code, when cleared it comes back. I understand it's down to the air horn under the scuttle panel. I've googled the code all of them say "no communication", the error code I have doesn't so what does the code I have mean? Do I need to replace the air horn or batteries inside the unit? I can't find the fuse....

Thanks

Ravs
