MIL, OBD setup for iOS

So, ‪after 2.5‬ seasons and around 10500 miles, I had my first bump in the road with my 2017 SS base model. Operator error of course. I somehow managed to leave my key in the bike in the on position after work the other day. I came out the next morning to a completely dead battery.

I put the bike on my Ducati spec and branded charger/maintainer (I know silly but Iím not taking chances). At lunch, I saw it was still charging but turned the ignition on to verify it was taking the charge. It lit up and all appeared well.

The next morning, it started fine and I noticed nothing unusual until a couple of blocks later when I saw the MIL was on. Having read that a low voltage condition could cause that light to come on (thanks forum), I continued on to work. The light stayed on through several on off/start stop cycles.

I called around locally and no one could read the error for me. The nearest dealer is 2 hours away so I decided to try and read/clear the code myself.

I ordered this cable

And on the recommendation of the helpful rep at Turner Tools this reader

While waiting for the parts to arrive the light finally went out on its own.

The parts arrived and on the second try, I found a free app that would connect:

It returned a low voltage error of type Ďstoredí using the generic OBD setting. It had the option to clear but still showed the stored error. Iím not sure if it would have turned the light out or not.

Iím still a bit puzzled as to why the bike doesnít put the battery light on for this but I guess it could be because I turned it on midway in the charging cycle, it threw the error and then stored it at shutdown. When I started it after fully charging, the condition no longer existed but it put the MIL on to alert me that something untoward had occurred.

Its been a week and the light has not come back on.

Love this bike.
