2022 Como no Eco-Sport-Turbo control

[GuruUno]

My wife and I went for a ride today and after a 32 mile ride with 53% remaining her bike died with no assistance whatsoever.

Upon returning the bicycle to the car, I inspected it and could find nothing to validate the reasoning as to why there was no assistance in Eco sport or turbo. When arriving home, I swapped out the battery from my Vado 5.0 to see if it possibly has something to do with that. It did not. I then took the bike for a ride with the different battery and went through the Eco sport and turbo mode with no response or assistance whatsoever. However, when I pressed the F2 button underneath the handlebar control , it allowed me to manually percentage wise go 10% 20% 30% etc. up to 100% assistance and through that procedure. The bicycle responded to providing pedal assist power.

I contacted my local bike shop. He asked me to bring it in he feels as though it may have something to do with the handlebar control. Has anyone ever had a similar issue and was it the handlebar control or was it something else.

Thank you

Does the display in this specific e-bike contain a button battery?

Specialized 2022 MasterMind Turbo Connect / Control Unit is newer than the older referenced type you mention.​

There is no battery in it.
It works, it displays, it shows eveything it is supposed to show, and it functions with the exception of the "modes" (ECO/SPORT/TURBO) as well as SMART
I contacted the LBS, he suspects the handlebar control unit may be defective, which he says he has spares, and will try swapping out to see if that is the cause.
Again, I can use the 10%-20%, etc., to 100% "mode" and there is response only via that method.
Very odd

The older model is Specialized Turbo Connect Display (TCD)

Dropped off the bike at the LBS on Tuesday, they 'think' it is a damaged/broken speed sensor wire. One is on order.
(the wire that goes to the sensor on the rear wheel/frame that gets its signals from the magnets attached to the rear rotor)
To me, the oddity is that although the MasterMind control unit performs and functions correctly, there is no control of any of the speed/modes via ECO/SPORT/TURBO at all, but yet you CAN provide assistance in the incremental range (10% increments) by selecting the Micro Tune function, that works fine.
They tell me that the MicroTune is basically an "override" and can do so.
We shall see.

OK, picked up the Como today from the LBS, he tells me that when I put on my kickstand, I pinched the wires for the BROSE SPEED SENSOR CABLE (V2), 650MM LENGTH.
I out that kickstand on almost 2 years ago, odd how it happened.
Anyway, $20 part, all fixed.
