5110 error on hisun sector e1

[Johnfr1414]

“I’m getting error code 5110 on my Hisun Sector E1 (2022 model) with the Sevcon Gen4 controller. The code appears during [startup/acceleration/etc.], and I haven’t found it in either the Hisun service manual or the wiring diagram. Does anyone know what 5110 refers to or how to clear it?”

Like you, I can't find any mention of that fault code, so anything from me is just speculation. You didn't mention if there are any associated symptoms, but generically the recommendations I can find are to check the wiring connections, especially between the motor controller and motor, and try a reset of everything by unplugging the UTV and disconnecting the batteries for some time so things can reset. I've seen some suggestions that it could be related to out of spec battery voltage, which is definitely possible if you're still with the original Discover batteries although that's not the normal 4C53 code we have all seen. If you want to go through the trouble you could fully charge the batteries and then individually check the voltages after disconnecting all of them from each other. Other than that, it's communicating with Hisun or a Hisun dealer, which can be a little hit or miss as I understand it.

5110, is not listed as a sevcon fault code, check and see if it not correct . To investigate further you will need a copy of DVT software and an IXXAT Can compact adaptor. (And an adaptor to the Hisun connector under the drivers seat.
