The NIU N1s’ main controller normally called ECU (hidden inside/behind the front panel) has an LED, and if it blinks, that’s a message đ
Here are the blink codes:
- 1 Over-Voltage warning
Battery voltage is higher than default value - 2 Under-Voltage warning
Battery voltage is lower than default value - 3 Over-Current warning
Instant current is higher than default value or Phase line short circuit - 4 Locked-rotor warning
Duration of Motor in locked-rotor status longer than default value
Replace FOC controller - 5 HALL failure
Incorrect HALL input(Voltage) detected
Replace Motor - 6 MOSFET failure
MOSFET power self-check failed
Replace FOC controller - 7 Phase default warning
one or more of motor phase lines missing
Replace Motor - 9 Brake applied
Controller in the braking status - 10 Self-test failure
System on the internal electrical self-checking found abnormal - 11 Controller over-heat warning
Temperature is higher than default value
Stop riding until FOC controller cool down - 14 Cable Hall Sensor Failure
Twist grip/Cable Hall Sensor Malfunction - 15 Alarm in active state
Alarm activated - 17 Communication failure
Communication between ECU and FOC controller failed
Replace FOC controller
Hey all I could not create a post so I am commenting on the most related topic. I own a niu pro bqi c3 ebike. The controller has gone bad smelling burnt. Do you know who makes this controller and where can I obtain a replacement one?
Thanks

Hey Christan – I’m not sure how many c3 owners are around here… what about your warranty and/or seeing your dealer? No option?
Are the codes different between the models? I sometimes get short failure code 12 on my N-sport and that should be FOC overcurrent warning.

Check your App, it offers Error-Code translation now!
Change to the “Me” page and it will offer “Error Codes” under Services… and yes, 12 means overcurrent.
Not good! Go see your dealer ASAP – the dashboard I’ve dissected showed clear signs of overcurrent through the CAN bus. I was told that the whole scooter behaved like cursed, i.e. all controllers were affected.
i have lingbo controller and it can’t use battery when i connecting battery the led always blinking and doesn’t stop i’m trying change another lingbo controller and still the same anyone know?
How to conect âblinkingâ with numbers? Number of blinking in minute or?

I haven’t seen the blinking myself, yet. But I assume it’s like with every blink-code: There’s a longer pause at the end of the code before it repeats.
