YAMAHA TECHNICAL BULLETIN: FEBRUARY 7, 2017

The button return springs inside the Handle 1 switch have weakened, allowing intermittent switch contact at start-up or idle.  Internal protection circuits prevent On-Command system mode changes while the unit is under way.

Solution: New switches have a stiffer-rate return springs to counter vibration and eliminate the possibility of intermittent contact that causes these On Command 4WD system mode changes.
