53 plate SE hazard faults

ok so I'm new to the forum and have done a few searches found nothing conclusive

I have a 2003 k12 with keyless system all of a sudden driving home the hazards starting activating sporadically by themselves the hazard switch completely had no effect

I pulled over removed the haz switch disconnected still faulty !

I stripped and disconnected the light stalk no effect !

I removed the keyless fuse 17 10a still working

I changed fob battery in keyless key ! No effect

Looking at wiring diagram all indicator lights work via the BCM and this also has a integral flasher relay is this correct ?

Has anyone had a BCM cause this error

Regards

Kev
