Critical Safety Note: Do not ignore this code. If the controller detects an uncontrolled speed deviation, it assumes a potential runaway condition. Continuing to reset and force operation could lead to a loss of braking, pedestrian injury, or damage to palletized goods. If you're unable to resolve the issue or

• Test motor encoder/hall sensors per manufacturer pinout: supply voltage present, signals while turning motor shaft slowly.

3.2 Damaged Drive Motor Windings – 15% of Cases

If the motor draws excessive current due to a shorted winding or a phase-to-ground fault, the motor cannot achieve the commanded torque. The controller commands more current, the motor groans, but speed remains low. The resulting deviation triggers Code 4372. This is more common on older EJE 120 units used in high-duty-cycle applications (e.g., beverage distribution).

Error Code 4372 is less common than basic battery or motor faults, but it points to a specific and critical area of the truck’s safety and control system.
