Installed a set of speakers on my bike last year, used the accessory plug under my left panel. Once in awhile my security light would come on, but went off within a couple minutes. This year it’s been on and stayed on. Checked the codes B2113 came on (Acc output shorted low) all lights work (except rear flashers in hazard mode) nothing else has been done electrically to the bike in the last two years. What would cause the “Acc output shorted low” code?
