Hi NeoRider
I had the same issue for me: just go to your dealer, he will take contact with Zero support, and they will connect to your bike and correct the Cellular connexion.

And a quick update after having firmware version 19 installed on my own SRF. I can confirm it breaks the remote connect function. Both soc and location are stuck since a few days at the point where the update was executed (dealer).

Never had this issue before on the bike and even still got the notification of bike being moved and route afterwards towards dealer. Moving it back didn't trigger that notification nor any other update.

Just got my bike updated by the dealer to V19. Same result  :-(.
Now I will let them know, what you guys already have found out (great forum!).

I just spent several months getting a new CCM fitted (under warranty).  It had to be coded to the bike which unfortunately the first that Zero sent out was not.  But after successful replacement it updates the Cloud status fine, but after the bike is keyed off for a couple of hours (next CCM update basically) then the SOC goes to 0%.  Key the bike on and leave for an update to occur and it is correct again.
It feels as though this is an issue with the new CCM sending back the wrong status when the bike is off.  But the dealer is stating this is a known issue with the App (Zero NextGen app that is). 
Anyone else with any further info on this issue?  I can't help but feel it's a simple config problem.

That's exactly how Remote Connect, on my 21 SR/S, works with v19.
(I don't have any experience with it, on v18 for comparison.)

Not completely sure, but SOC, via Remote Connect, also seems to work;
When Actively Charging?
For a short time, after plugging in a Charge Cord?

Does that match anyone else experience?

Greetings! How did you solve the problem with undercharging the battery to 100%? I have Zero S 2014 and it has a problem too...

my ccm is faulty from the beginning ( february ) and i have open a ticket to my dealer, and i call it every week for status... but at today nothing.
my current ccm have 2 problems, it never report soc % and charge status to the server,
but the worst problem is that after a server position update ( with bike in motion) it hang, simply ccm go to low power mode and never wakeup, to fix this you need to disconnect 12v battery.
if bike is stationary it update server position without issues every time you turn on key.

running a canbus trace on the communication lines, the bike send soc % and fw ver to the ccm every sec, and ccm send back the info you see in the diagnostic.
as soon it hang it disconnect from bus and all the data transmitted from mbb is not captured.

i have also found canbus messages (id253) with soc 0% sent to the ccm  at key on, this is likely the cause of the bad soc% reported to the server (if ccm update the server with this value)...and i think it will be addressed by a new MBB firmware soon or later... (i'm running MBB v24)

p.s you can check the real data sent from ccm to the server with the following info https://www.electricmotorcycleforum.com/boards/index.php?topic=9520.0
cause app can be bugged too

Hello from Portugal,  just by the way on my 2016 FX  which i use since 2019 i never made an Update. And everything is working well. Although  whole power untill around 30% SOC.  Maybe it is a Friday-Weekend production.  When i read all this things i wonder little bit, why people make updates with this expiriences. Ánd what is the problem with good Software Engineers around CA ?  I m be anxious how long my Bike is running. Range is going down...   Is it right that 2017 Modells available with  Modular and Longbrick ?  Ola, Alter

Just an update on my own CCM issues / situation.
I tried time and again to prompt the dealer, and Zero UK, I received silence.  I think these units are temperamental and so I suspect there are many root causes to what is the same symptom (no connectivity).
I decided to go in and investigate myself.  I had previously removed the 5v fuse to the CCM with no luck whatsoever.  The bike still reports “Cellular” status as “Not Connected”.  So I proceeded and removed the tank plastics (easily done) and removed the CCM module, which is just behind the ignition switch and secured with cable tied.  I just cut those and then removed the rubber boot that prevents water ingress.  The plastic housing is held closed by a single small screw.  Removing this I can see there is a sim.  I popped this out,  then put it all back together and connected to the bike.
Keying the bike on and the status showed as “Connected”.  I had forgotten to put a little internal plastic cover back on and when I did so it reported “Not Connected”. I took apart and reassembled (all whilst connected to the bike and keyed on) and it flipped to “Connected” again.  Loose wire connections?  Flaky cellular connection?  Unit upside down?  I’ve no idea.  After a few hours the bike is staying in a “Not Connected” state when keyed off and “Connected” when keyed on.  I remember a firmware fix was supposed to resolve loss of connectivity when the bike was off and not charging.   I’ll continue to monitor, fingers crossed I at least have connectivity when it’s charging - that’s the bit I miss; ie when should I go back to the bike if I’m not in Bluetooth range. 

Paul.

what crap this ccm, on my srs/s 2021, it hasn't worked since January 2022.
my bad dealer, can't do anything about it, they don't want to bother.
I would have been curious to see the photos of the open ccm...

[PaulZero]

There is a decent post on Facebook with good photos.  Hence I didn’t feel the need to.  It’s referenced in the ZeroManual unofficial site.
