Jungheinrich EJE 120 Error Code 4372: Causes, Diagnostics, and Full Repair Guide
The Jungheinrich EJE 120 is one of the most reliable electric pallet trucks in the logistics industry, prized for its robust build, intuitive controls, and efficient energy management. However, like any sophisticated piece of material handling equipment, it relies on a complex network of sensors, controllers, and actuators. When something goes wrong, the truck’s onboard diagnostics system displays an error code to guide technicians.
Ensure the battery is healthy and maintaining voltage under load, as low voltage can occasionally trigger secondary control errors. Consult Service: jungheinrich eje 120 error code 4372
Immediate travel cut-off – The truck moves very slowly or not at all.

Code 4372 stored – The error remains in memory even after cycling the key (active until cleared or fixed).
No other codes – Sometimes 4372 appears alone, but it can also accompany hydraulic temperature or voltage-related codes.
