GS-911 Wifi / Re: "Ignition is not ON" error message

« Last post by botus on April 10, 2026, 09:57:43 AM »

does the bike start ride and have all functions (lights indicators, cluster etc.) ?

something is very strange if above works but the tool can't show the ignition switch status - what condition is the bike? - is it std, low miles and good condition ?

if its playing up on the bike and the tool - two wear items might not be helping - ignition switches can wear - not the key, the switch beneath, and these days a main module the ZFE are starting to fail due to ageing - but these would likely present as real vehicle faults

ZFE's on cars these days are often referred too as body control modules - and really control lots of axillary functions like lights and systems (rather than brakes, transmission or engine control)

GS-911 / Re: Any remedy if getting 'over-voltage' warnings with a NOCO NLP14 lithium battery?

« Last post by WayneC on April 10, 2026, 03:52:33 AM »

I figured you cannot change the voltages, and neither on a car. But changing the battery type takes care of any voltage differences, along with setting the proper Ah rating. But our bikes apparently have none of that. Or at least the GS-911 does not have that capability.
I remember somebody saying a dealer can actually change the battery to lithium, since it's optional on some bikes. But again, the GS-911 apparently can't do that.
At any rate, those lithium batteries supposedly have an internal BMS that is supposed to compensate for any differences with an AGM battery, so guess we'll see with this NOCO unit.

The GS911 can only perform the functions set by BMW in the ECU firmware, sometimes it takes a little time for GS911 to include all functionality in the ECU's

Changing battery model/AH/Type is only possible if BMW include that ability in the ecu's & firmware/iLevel updates by BMW may add battery types/models hence it can be good to keep iLevel up to date, it can also be useful to specify iLevel in forum posts as it then enables those who know the latest iLevels on a bike to let owners know there are updates available, unfortunately BMW dont provide a lot of info on what is in iLevel updates

The dealer ability to change battery type to Lithium will only apply to the models BMW have programmed into the ECU's the ability to do so

Re Lithium battery BMS, not all Lithium batteries have an internal BMS & the internal BMS is not there to compensate for differences with an AGM or other Lead Acid battery types, it is there to monitor charge of the individual cells & in some adjust the charge rate into individual cells

The voltage requirement for coding/programming/resets is set in the ECU firmware not the GS911, it can even be set within individual job scripts in the BMW Dealer Diagnostics system, with the cars 14v is the minimum voltage required, the Motorrad division was a little slack in specifying minimum voltage & the last time I looked it was specified to be 13.5v. On the Husky Terra 650's released over 10 years ago you cant even do a service spanner reset without 14v

Regardless of model when doing any diagnosis I use power supplies/chargers which maintain 14v

The battery registration capability only applies to later more modern models & is to optimise charging curves & is also used to turn off/minimise charging when heavy on the use of throttle which improves throttle response

GS-911 Wifi / Re: "Ignition is not ON" error message

Thanks for the info.
I've installed the new firmware and the Diagnostic for Windows,  v2603.5 and Android.

I've connected a battery charger and the voltage stays in the high 12 volts.
Whether I start the Diagnostic with the ignition on or turn it on after the error message I still see the same behaviour.
In the former case I have never managed to see the 'Ignition ON' icon in the notification bar go green and the key indicator move to the vertical position. In the latter case the key icon goes vertical and the circle turns green for 1 or 2 seconds then the Ignition not on error appears.

I see this behaviour on both Windows and Android apps.

As I mentioned in an earlier post, 2 yrs ago, using the Android Diagnostic I had gotten deep into the functions. Now, I cannot even connect to these features.

Apparently only 1300s have the capability of registering new batteries, and maybe changing to different types as well.
I've been reading many reviews about NOCO NLP14 batteries, and the majority of folks don't have any issues. It could be charging issues, since charging with regular charger that has a desulfating cycle, fries the battery. Hard to know. But a 2019 RT owner, which is basically the same thing as my 2020, since newer RTs have a different charging system, with a larger battery, so will go on my test mountain trip, and see what happens.

GS-911 / Any remedy if getting 'over-voltage' warnings with a NOCO NLP14 lithium battery?

« Last post by JCtx on April 09, 2026, 06:47:15 AM »

Just bought it today, and doing some research, several BMW riders (with 1250RTs) reported those warnings, and ESA not working. Since my bike is a 2020 R1250R (the naked one), I'm bracing for the same errors when I ride the bike tomorrow. But want to know if there's a remedy, or have to go back to the AMG I just removed. The main reason to buy the NOCO was that after updating my GS-911 to the latest version, the voltage threshold went up again to 12.5V, I can't do squat with the AGM, even though it's fully charged, it's the more powerful version (YTX14H-BS AGM), and I activated it myself, and fully charged it before installation, so it couldn't be any fresher. Even with my 5A charger connected, it's below 12.5V in less than a minute, so can't do anything. So frustrating. Why was it raised from 12.3V to 12.5V again??? I never had any issues, until the latest software versions.

Anyway, I looked everywhere on my Wi-Fi GS-911, and couldn't find anything related to the battery. So cannot change it to 'lithium', cannot register a new battery, cannot reset anything, and cannot increase the voltage threshold to avoid those warnings. Did I miss anything? If yes, please let me know where it is. Thank you.

Finally, can the higher voltage of these lithium batteries cause any issues on the bike, other than the codes? Newer bikes I think came with lithium batteries, so there must be the option, no? Or are those batteries' BMSs supposed to take care of any differences? That's supposedly the case with the NOCO NLP14, but maybe not. Really curious if it acts up on my bike. But if it does, and there's nothing I can do with my GS-911, would have to try to return it. Thank you.

EDIT: I want to change my login ID (to 'JCtx' too), but couldn't find how. Does anybody know how to do that, or who to contact? I didn't remember my stupid handle, so want to change it for the one I use everywhere else. I'm getting old. Ha ha. Thank you.

General Discussion / Re: K1600 Misfire but No report on GS911

« Last post by Radian on April 07, 2026, 11:31:53 AM »

Though on my 2013 I did find the coil misfire indicated just after I bought the GS911 diagnostic. At that time I replaced only the defective coil and the bike is still without problems today and at 32k km.

I will check the exhaust temps with thermal camera (lucky to have one). But maybe I should just replace the whole lot because this (2017) bike now has also 32k on the clock and has not had a problem yet so likely it is due.
I also will just check the fuel. Somehow nagging feeling that this misfire started not long after I filled up at a fuel station I have not used for years.

Thanks for your response. Seems the Hex forum is kinda dead if you ask me.
