On my '06, I have had a few occasions where I put the back brake on first, applied the front brake and had the ABS cut in at the front - even if I was braking lightly. Not good.

So, it went back to be checked out. Now, apparently, Yamaha do know about this, although they haven't issued a bulletin. The problem is that the fluid between back and front can "seize" if the bike has stood around for a while (like in the showroom before you buy it) and the linked bit applies the front caliper and never lets it go - so the ABS gets confused and starts working.

The cure is to run some diagnostics and flush the fluids a few times (so I am told). Whatever it it is, my bike has had it done and I haven't noticed the problem since then.

So, if it happens to you, get the bike to the dealer and get them to sort it out.

Could this mean that each spring I have to worry about this happening to me because it's been sitting in my garage for 5 months over winter?

Not good at all!

Don't know - that's just what the mechanic told me. It could be that once it's been flushed through, it's OK for ever - or not !

Look after your ABS if you want it to look after YOU !!

Seems like some things never change, I have 6 bikes one of them being 94 GTS 1000 with ABS. The only way to keep any anti lock system working 100% is to use it regularly I mean at least one every month you will have to brake hard enough to make the system cut in and move the static fluid in the modulator, no problem with the rear brake just about anybody can cope with jumping on that pedal hard enough to attempt to lock that back wheel forcing the system to move a little fluid through the modulator, however it is a massive test of faith to grab the front brake hard enough to lock the front wheel!! And force the system to cut in and save your sorry arse. The alternative is to get you dealer to show you where the test plugs are for the ABS control unit, with the GTS you simply have to link 2 pins on a plug under the seat, apply pressure to both the front and rear brakes, then with your spare hand turn the ignition key; If all is well both levers give a good kick, the front lever ratchets back to the bar and the rear brake pedal depresses fully. Release the brakes turn off the key remove the link and fit the seat all done on the main stand and no risk of gravel rash. Unfortunately the warranty had long since expired on my GTS when I bought it and tested my ABS, it failed the test left me with nothing but a red light flashing on the dash. I stripped and rebuilt the modulator it is a mass of solenoids valves balls and springs and o-rings. There are no spare parts listed Yamaha only offer you the complete unit at an intergalactic price. My advice is test cycle your ABS system often and change your fluid frequently don't be dumb enough to think the dealer is going to do it with a reminder.

A manual test of the ABS system sounds like a reasonable thing to do, but if it's required I'd hope that it would be part of the normal service schedule and something my dealer could perform or is simple enough that I could perform.

Anyone have instructions on how to trigger the ABS manually on an 06?
