Help thread: Yamaha FZ6 sidestand switch wet but diagnostic mode says normal
I am opening this because the search results for Yamaha FZ6 sidestand switch wet but diagnostic mode says normal are a mess: three short answers, two miracle products, and one guy saying 'just sell it'. I can read codes with a basic scanner, but I do not fully trust the tool yet. Should I confirm voltage, grounds, and connector condition before chasing the code?

5 repliesFor Yamaha FZ6 sidestand switch wet but diagnostic mode says normal, I would not start by clearing codes. Photograph the code, check battery voltage at rest and while cranking, then inspect the connector related to the system. A weak supply can make a scanner sound more dramatic than the bike really is.
Also check whether anything was changed recently. The last hands near the bike are often the first suspect, even when those hands are our own. That is how I would approach Yamaha FZ6 sidestand switch wet but diagnostic mode says normal before spending money.
