TQ HPR50 / HPR60 error codes
TQ shows “ERR” (error) or “WRN” (warning) followed by four characters, for example ERR 0401. TQ’s table groups the codes by the first two digits: 04 motor, 06 warnings, 44 battery, 50 range extender and 54 display and remote.
Trolda reads live data from TQ HPR50 / HPR60 bikes. What Trolda shows on your bike
