Kenevo SL Kenevo SL electrical gremlins advice

[Benjooo]

Hi guys, looking for some advice or an answer if possible regarding current issues my 2022 Kenevo SL

In short, last april/may time at BPW the motor packed up after a small off mid corner, bike just fell to the floor at slow speed as I slipped out and didnt power back on.
Went to Specialized Leicester and they replaced the motor under the warranty scheme, 2 months later I start getting poor performance from battery and max charge limit 90% so I replaced the battery myself (a qualified LGV and car mechanic of nearly 20yrs), then bust my collarbone and the bikes parked up for nearly 3 months. Once back at it bikes working great while riding but needs me to pull mastermind before every ride to unplug and replug (ended up taking a t10 out with me on every ride incase it turned itself off)
Eventually bored of this fault early this year it goes back in to Specialized Leicester and has a software update, bike works great in the shop, I take the bike home (nearly an hour away) and a week later on the first use a warning message appears 'No motor check app' so phoned Specialized they told me id now need a new wiring, so went down yesterday and collected the loom, took the bike back to them for code clearing and software update again, road test the bike for 10miles at a local park, performed perfectly.. Came back to it this morning, entirely dead, wont turn on at all, pulled the mastermind and tried the unplug replug trick a few times, nothing, tried to to plug the mastermind into USB to charge, nothing, tried reconnecting the entire system and charging through bikes main charger port, nothing, tried the function button reset and mastermind is entirely dead.
Ive been back and forth to specialized a number of times now and its nearly an hour each way for me so this is becoming expensive and annoying to deal with when I was told everytime it goes in theres no fault with it yet their obviously is.

In less than 12 months its had the motor, battery and wiring loom replaced and its just never been right since the original fault of motor failure, could this now mean the mastermind has finally failed too?

Appreciate thats a long post but wanted all the details up so I wasnt getting into a back and forth about what has and hasnt been done so far

Any help is appreciated at this point

Sorry to hear about your issues, especially when you’re in the realms of replacing components piece by piece.

Sounds obvious, but I’d say the TCU is now completely dead. Whether it’s just coincidence or related to something else going on with one of the previous faulty components replaced, hard to say.

The other reason I say it must now be the TCU/Mastermind is the symptoms of it failing to turn on unless you unplugged the TCU first is what my Specialized Levo SL was doing. After a while though nothing would coax it back to life, but fortunately the new TCU sorted it.

At least when that’s been replaced, everything will be ‘new’ and it should rock on for a good while.

Cheers for the quick reply, i ended up playing around with the electrics yesterday, turns out the USB charger i was using for the TCU was a bad charger and once id used a new charger the TCU fired up sound and performed without fault.
Once id got the TCU to fire up, I was then getting all the miscommunication messages again between motor and battery, ended up with 4 different fault codes in mission control at one point, then the bike fired up and worked for 3 cranks and shut itself off, pulled the battery again and got it all working fine for a moment, plugged it back in and it accepted charge from 74% to 92% then completely shut itself down again, I had to pull the battery again to relight the system.. Its going back to the dealer.
Im absolutely certain the fault is inside the replaced motor, its almost like its intermittently making and breaking connection somewhere internally. Since it originally faulted at Cannock 4 weeks ago when it slipped under crank while riding up a hill, no amount of repair has fixed it since and the motor sounds like its screeching inside when the cranks turn..

Im going to try Specialized in Birmingham today and see if their team is any more helpful on the matter.

But thank you again for your reply.

So the nearly 1 year old replacement motor is now screeching and otherwise playing up?

In that case, the TCU is probably right when it’s reporting that there’s ’no motor’, if it’s faulty, but the TCU/Mastermind is a critical bit of kit and if it isn’t working properly rhen you will get all kinds of phantom errors and weird behaviour from the system sometimes.

Worth checking the wiring loom again to make sure it’s plugged into the motor properly and there are no cables pinched before you take it into the Specialized shop again.

It’s always possible that you’ve got more than one fault going on of course!
