'20 GEM fault code 168:4

I have a 2020 GEM e4 that I just replaced a Battery Temp Sensor due to having a fault code 520358…problem solved. However, just a few days later the same car is now not able to move R or F, but dash is fully illuminated with a new fault code of 168;4.

168:4 code…System Voltage Low, This Trouble Code Sets if the System Voltage is Too Low after the Engine has been Running for a Specific Period of Time. Can be caused by Damaged Wiring/Connections or a Faulty Stator/Regulator.

Has anyone come across this problem and had resolution? I can go to the 3-terminals (U,V,W) for the stator leads on top of the motor to check for continuity and even check the motor’s temp sensor…but that all checks out. Does anyone have any suggestions what I could do/check next??

Can you put a meter on your battery and get a reading on what your pack Voltage is? Clamp it directly to the posts and take it for a ride, mash it, then see how much it drops.

Then clamp your meter to your controller and see if it is the same, or drops lower when under load.

When was the last time you plugged it in for a full charge?
