I also installed the GiPro Gear Indicator on my bike. It ran perfectly but after a day or two it stopped working.
Attached a pic of GiPro gear indicator on my bike when it was working properly.
The console shows a "CAN" error and most of the things stop working along with it. It shows LO Battery, Neutral light doesn't work, nor does the bike start

As soon as I remove the Gear Indicator from the diagnostic port (that's where the indicator reads the gears), the bike works properly and everything comes back to the normal
Anybody else face this trouble? If yes do let me know. Any help would be appreciated.
