ABS Light Flashing / ABS Not Working

Hi there, I have a '04 silverwing with 12.000 miles (just had a service where the brake fluid, air filter, spark plugs etc. were changed etc.)
10-15 miles after the service the ABS light started blinking and the ABS system stopped working. The stealership says they need to change the ABS ECU , but I'm sure it's something much more simpler than this. Has anyone experienced the same issue? What would be your suggestions to diagnose the cause of the problem?

Chances are 9 out of 10 that they didn't bleed the brakes completely / fully / correctly (delete as appropriate). And/or they've gotten brake fluid on the rotor.

If that does end up being the issue then it's time to change to a dealer that actually knows what they're doing. Ya really don't want some dick-fingered wrench fooling with your ride --"Gol-ly, always wanted t'fix me one-a them scooter thangs".

My "guess" - a failure to properly bleed the brakes. That "guess" does not preclude the ABS ECU could have failed, it just seems more likely that they did not do a proper bleeding of the brakes.

Now then, some shops do not do a full brake fluid replacement. Some shops will just siphon out the fluid in the reservoirs and then refill. Not a very kind way to do the task, but it happens.

However, I have not experienced this problem and am truly not familiar.

Not really sure. Surely the dealer can double-check their own work to find out. Either that, or find someone (maybe yourself) to do a quick brake system bleed; which should eliminate that aspect. I'd think if the system operated ok for awhile, then failed, that the ECU could also be a plausible cause. But do the simple stuff first.

And "CJ"... could we watch the salty phrases ? ? ? I'm no prude but this is hardly the place for such things.

I love that description.

Point taken DickO.

Sorry if you were offended.

I just ordered my stainless steel speed bleeders from http://speedbleeder.zoovy.com/category/stainlesssteel. There is a non-stainless steel version which is cheaper.

3 - SB8125L Stainless Steel speed bleeders
1 - Speed Bleeder Bag & Hose Combo
1 - Sealant ( http://speedbleeder.zoovy.com/category )

It may help quickly remove any air bubbles from the system and make it much easier for you to change yourself in the future.

Thanks "CJ"... that was very kind response.

the issue was with the abs sensor on the front wheel, I got it fixed pretty quickly and everything's back to normal. thanks!

Told you I had no real clue.

Glad it was a quick fix.

Thanks for letting us know ... I am sure that this will help someone in the future.

Was the ABS sensor "bumped" during service or was the front wheel removed?

neither, I'd ridden it for a while after service and everything was ok, then I didn't ride the bike for a few days and then the next time I got on it the abs light lit up so I'm not sure what caused it
