My bike is a tattle tale

Ducati Dreams · Jun 12, 2012

Just got done with the first service. Previously I had disconnected the exhaust flapper valve and then I reconnected it. The service guy asked me if I was having problems with the valve and I said I disconnected it and reconnected it. He stated that the diagnostics revealed an error code when I did this.

So I guess these bikes are smarter than we thought eh.

That's On board diagnostic which has very very very very long existed in car systems since the 80s...,till today be it airbag, ABS,engine controller,HVAC,ESC.....
The standard checks for Open Load, short-batt,short-GND for each actuators and sensors by the ECU.
It will be a mechanic nightmare checking through the all or whole wiring harness with these faults by hand with just a multimeter.

I can't answer for motorcycle on board diagnostics (OBD), I haven't worked on bikes for over twenty years, had to switch to cars to make enough money to feed the kids. Automotive OBD is a fantastic diagnostic aid, with the right equipment there is so much information availible it really cuts labor time. The technicians who don't like it haven't spent the time to learn how to take advantage of it. My guess, for what its worth, is the motorcycle OBD system is similar, a great tool if you know how to use it.

...and you are surprised by this? That's what computer's do really well. Remember things.

I guess where I was going was that people where saying they disconnected their exhast valve and didn't get a error on the dash. However, my point is that even though the dash read out didn't show and error...the on board computer didn't like it!

Sure.

Anything with an OBDC will probably report 50 things every time you take it in for a service.

There doesn't have to be something critically wrong that might require a dash light to light up.

It'll log anything that isn't quite right.

...and if you run track mode and use the lap timer or have DDA I imagine that there is even more in store for the mechanic to review. (And the police or insurance in case of an accident.)

I am certain the their are certain 'high water' marks that are recorded and stored as well. Things such as max RPM acheived, max speed, high temp, etc... Chances are all of these are lost if the battery is disconnected. (I base this upon reading the manual and what it will store and recall in the lap timer).

I remember taking my GSXR in for a service back when it had about 5000 miles on it. The servo motor for the exhaust valve went south and I took it in to be replaced under warranty. When I went to pick up the bike the service manager told me that he had never serviced a 750 that had displayed 186 on the speedo (172mph actual with +8% speedo error). I asked him to please keep that quiet and from then on I always disconnected the battery prior to taking the bike in for any service to erase those high water marks.

Will that be the case for the 1199 though? Disconnecting the battery might not wipe the data. Also, isn't the dda on the tri something you have to turn on for it to capture data. The thing isn't in 24/7 logging everything.

This emphasises the importance of breaking the bike in as suggested by the warranty. If you have a significant (costly) issue and seek work under warranty, Ducati could require data from the bike be submitted as part of the warranty claim process.
Just saying...

all are same, suppliers for the controller(s) used in cars are also supplying those for motorcycles,magnetic marelli, kehin,SVDO (belongs to Continental), Robert bosch just to name a few...

motorcycle is a low entry-barrier for their business but the volumn is just a tip of ice-burg of what they can really make in cars....
