    Probably going to need to email support on this one. See if you got both the controller and motor order numbers.

    Dear Eric / Paxtana
    I just installed new controller and getting 11h
    error and beep . I know this is something to do with temp sensor ? how do I trouble shoot ?
    or is it ghost error ?? it clears momentary when brake is used ? please help this is brand new ludi controller . thanks

    Sounds like you should follow the troubleshoot guide, it is step by step

    At a guess you are probably looking at replacing either the harness or controller, maybe both

    I’m struggling to diagnose our issue with our Bafang BBSHD Mid Drive Ebike Kit. We put that kit on a Yuba Mundo cargo bike and once we had about 150 miles on the kit/bike, the thumb throttle stopped working. I got a new thumb throttle and I plugged it in and it spun the wheel for about a second then stopped and the display showed an error of 30H. Other than the throttle the bike was working fine so we just kept riding it without the thumb throttle. Now the bike has started acting weird enough it is unsafe to ride with the electric unit on. We have 3 kids and I noticed the other day when we were all on it the pedal assist was cutting in and out very rapidly. Kind of sputtering. There was the 04H error code. I tried riding it again and no error code was being displayed, but sometimes the motor gets stuck on and you have to lock the brakes to get the bike to come to a standstill. Sometimes the motor doesn't work at all. Sometimes the motor sputters. It does not display any error codes anymore. I took it to a local bike shop who had an extra display lying around just to see if that would be the issue and plug in a new display in made no difference with the thumb throttle or the behavior of the bike . We're wondering what next is? All connections look good and clean with no bent prongs or crushed wires so we are wondering if it is the controller unit or something else? Maybe shift sensor? Do you have any advice on this issue? Thank you.

    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.

    Remove the chain and chainring, gently pull the controller, unplug the white connector going from the controller to the motor, check if all the pins are there and straight, check that the plug pins are not bent plug it back and test again. Then unplug the PAS connector (4pin black connector between the controller and the motor) and leave it unplugged and try your motor again using the throttle, if the Error 8 disappear and the motor runs and then it's a bad PAS sensor. If not then it's likely a controller or motor core issue. Watch this video at 3:25min mark :

    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 or firmware issue*

    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 or that the sensor is defective (click here for help). 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 , a throttle or the controller. If possible troubleshoot with another display and throttle (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:

    As you can see a lot of them are not used in the current version of the BBSXX series

    Please see error code table below, Hexadecimal will show H behind.
    0x01 Normal No error No error
