Models with KD21C or KD218 Displays

Error codes may only be on the display briefly. If you experience an issue, safely glance at the display to see if there is an error code. If the information below does not resolve the issue please contact us HERE - Ride1Up Support


CODEERRORDEFINITION SUGGESTED FIRST STEPS
21Voltage Current ErrorThe battery is not supplying the required voltage to power the display and motor. This can be caused by working the internal controller, motor, and/or battery too hard in some cases (long extended climbs with the rider not pedaling hard enough).Safely pull over and shut the bike off. Wait 5 minutes and then turn the bike back on.
22Throttle ErrorMost commonly caused by a physical hardware issue (lever stuck down, damage, etc.)When you press and release the throttle, it should return to the original position. Check for and remove any obstructions. Check the throttle and throttle cable for damage, such as a cut or frayed cable, or loose connection point.
23Motor Phase ErrorThis error might appear if you don't reconnect the cable after removing the rear wheel (for example, after changing a flat tire, or transporting your bike in or on on your vehicle). Check the motor cable connection point by the chainstay. Check the cable connection, disconnect carefully, and make sure it is free from grit or contaminants, properly aligned, and firmly connected. 


24





Motor communication or hall sensor error

At least one of the motor phase wires has been damaged or is temporarily disconnected. Another possible cause is damage to the motor cable as it exits the axle, perhaps if the wheel was dropped on the cable or something hit or pulled the cable.Check the motor cable connection point by the chainstay. Check the cable connection, disconnect carefully, and make sure it is free from grit or contaminants, properly aligned, and firmly connected. Inspect for damage throughout this process.
25EBS (Electronic Brake Shutoff)

Core-5, 500 Series


This can happen often after a crash or when the bike is dropped. Disconnect the electronic brake shut-off wire 1 at a time to determine if it is caused by 1 or both. Inspect both levers for signs of damage or lever not returning to the proper position 
25EBS (Electronic Brake Shutoff)
700 Series Tektro Brakes 
This can happen often after a crash or when the bike is dropped, where in these cases . Disconnect the electronic brake shut-off wires 1 at a time to determine if it is caused by 1 or both. Adjust the brake lever/sensor that is causing the motor to cut off. 
26Low VoltageThe battery is supplying too low a voltage to the motor controllerCheck the battery voltage and terminals 
30Communication ErrorThere is a problem with the connection from the internal controller to the display. The display is not receiving vital information. Often, the issue is a stressed or damaged display cable; however, it can be related to the internal controller and, in rare instances, the motor.Check the display cable for damage; tears, corrosion, etc.

CODEERRORDEFINITION SUGGESTED FIRST STEPS
07
overvoltage protection
The battery is supplying too much voltage to the motor controller
check the voltage of the battery and charger
08
failure of motor's hall signal wire
The motor cable may be damaged, disconnected, or loose
check or replace the motor and wiring
09
failure of motor's phase wire
The motor cable may be damaged, disconnected, or loose
check or replace the motor and wiring
11
failure of the controller temperature sensor
The controller has reached is maximum temperature or the sensor is faulty
Turn the bike off to cool down. Check or replace the controller if error persists
12
failure of the current sensor
The battery is supplying too high a current to the controller
check the controller and battery
14
failure of the temperature of the motor
The motor has reached its maximum temperature
Turn the bike off to cool down. Check or replace the motor if error persists
21
failure of the speed sensor

The speed sensor in the motor or wiring is damaged
check or replace the motor wiring and motor
30
communication failure
One of the components is unable to communicate with the motor controller or is faulty
check the wiring and the connectors of the controller

7Over-voltage protectionOne of the sensors is seeing too high a voltage or is faultyCheck cadence sensor and throttle
8Motor Hall cable malfunctionThe motor cable may be damaged or looseCheck if the motor cable is damaged or loose, disconnect and reconnect
9Motor Phase cable malfunctionThe motor cable may be damaged or looseCheck if the motor cable is damaged or loose, disconnect and reconnect
10Motor Temp Too HighThis happens when the motor gets too hotPower off the display, wait until the motor temperature cools down, and start to have power again
11Motor Temp. Sensor malfunctionFailed motor temperature sensorMotor replacement needed
12Current sensor malfunctionCurrent sensor malfunctionInspect controller cables
13Battery Temp Too HighThis happens when the battery gets too hot the battery management system will cut power from the battery to prevent damageInspect the battery and shut it off to let cool down, once cooled down continue riding
14Controller Temp is too highThis happens when the internal controller gets too hotInspect internal controller connections and shut the bike off to let cool down, once cooled down continue riding
