    BBSHD BBS02 Error list

    Error 04 Throttle no homing, Unplug the throttle, if the message clears up, it's time to replace it!

    Error 05 Throttle abnormality: Throttle maybe damaged and not working, or the throttle may only work intermittently, Check throttle casing for damage, check wiring for a loose connection to the battery. Sometimes might happen with an installation where the motor is pinching the wiring exiting controller.

    Error 06 Low voltage protection: Your pack is probably at 41V (48V pack) or at 44V (52V pack), if not try to program your controller to the right LVC

    Error 07 Over voltage protection: Wrong battery pack installed use only 48V or 52V nominal

    Error 08 Hall sensor: Sometimes corresponds with grinding noise: Check the motor plug to make sure it is connected properly, unplug and replug. May happen if the motor has been unplugged.

    Next would be to unplug the white connector going to the motor, check if all the pins are there and straight,Check that the plug pins are not bent. Watch this video at 3:25min : https://www.youtube.com/watch?v=rgFQK-ID8AM

    Another test worth trying, Unplug the PAS connector (4pin) and leave it unplugged and try your motor again, if the Error8 disappear you will need to change the PAS sensor.

    If you still get the Error 8 then If you are a true DIYer you can open it and check if the hall sensor board is still fixed in place. You can test the hall sensors and change them if needed. If not best is to start with a controller replacement (as it's the #1 cause for error 8) and then move to replacing the motor core.

    Error 09 Phase line abnormality: Broken wire or circuit, Check wiring loom for breakages.

    Error 10 Controller overheat: Temp sensor in the controller is triggered, let is cool a bit.*Possible phantom error*

    Error 11 Temperature sensor in controller abnormality, same as Error 10, *Possible phantom error*

    Error 12 Current sensor abnormality, Possible shunt blown in the controller, contact your supplier

    Error 21 - Speed sensor error. Your speed sensor is disconnected or broken...check it or replace it. It may be that the sensor is not fully plugged in, not fully screwed into the plug, or that the magnet is too far from the sensor. Speedo sensors can be bought here. It is also possible for speedo cable to be ripped out of the controller if the sensor gets tangled in the spokes, in this event the controller may need replaced.

    Error 15H - Speed sensor error for the 750c display. Same as the above.

    Error 30 - communications/controller error. Most likely a display problem, a wiring harness or the controller. If possible troubleshoot with another display (if you have access to one) .....
    • Check your wiring harness for damage or bent pins. Pay close attention to the wiring as it leaves the controller going to the wiring harness, making sure no part of the wiring has been smashed by motor flex or random debris
    • Check if you have extensions for the brake levers, throttle or gear sensor. Unplug everything before testing, then test by plugging each component individually in and power cycling the system.
    • Check that you are not pinching the wiring leaving the controller, or the installation is causing the wiring to be pulling out of the wiring exiting the controller.
    • Unplug all plugs in the controller as shown here, then plug them back in.
    • Click here and follow step 2 for bypassing the LCD


    (!) This is comes up when the ebrakes are engaged. It may also come up when using the gearsensor, or if the ebrake/gearsensor plug is being short-circuited. Unplug the brakes, unplug the gearsensor, check the pins on the plugs to make sure there's nothing being shorted. Often this can happen just from the brakes being improperly installed.


    If all seems fine, time to try replacing the controller.

    Addendum: Error 15H on 750c display is same as speedo sensor error. Either the sensor is broken, not plugged in all the way

    Here is the full list of possible codes on the BBSXX motors:
