After clearing the b1122 code, when you once again blow another fuse,,does another b1122 get stored?
Did you happen to only check the left side sockets/bulbs/wiring or did you check both Left & Right sides while you were at it.
Have you ever got on the bike and started it,, then while riding suddenly loose your turn signals (one minute they were working & the next minute they were not). Trying to find out if the fuse blows AFTER a successful start up and during that particular key cycle.
