Kenwood Error 3655 - Speaker not working

Am hoping somebody can please advise me on how to resolve a situation that has occurred on my T6.

I have a Kenwood DMX8020 Stereo fitted with Focal Ibus2.1 under seat powered sub with 2 channel amp for door speakers, focal access 165AS component door speakers and 2 x 8" speakers in the rear tailgate (not amped)

All this has worked fine for the last few years, however a couple of weeks ago, while travelling back from Wales to Dorset all the speakers stopped and the Stereo gave the message "There is an error in the speaker wiring. Please check the connections - 3655"

Maybe it was a coincidence but it happened after I'd slept in the van for a couple of nights (although as it's a campervan, I've slept in it many times). The error came up about 20 mins into a 4 hours journey (it was a quiet journey thereafter!)

Within 24 hours, most of the speakers started to work again, with the exception of the front left Mid and the rear left.

This week I had to travel from Dorset to Wales again and on the way there, the front left Mid seemed to be working again, but on the way back, again about 20 mins into the journey, I got the same error and all the speakers stopped playing any sound.

This time, it hasn't started to work again... I've googled the error code and it suggests possible problems could be; faulty wiring, software glitch or hardware malfunction, like a damaged CAN bus.

Is it possible for the CAN bus to fail? Or do you have any other suggestions as to why this is happening? I was wondering if I can just replace the CAN bus with with the one Listed Here

Any help you can provide will be gratefully received as it's rather dull driving without any sounds :)
 
Could it be a loose wire or connector that worked loose and then after a few bumps connects again. I bit Low Teck perhaps.
