The circuit board inside the tiller head (responsible for throttle, lift, lower, and horn signals) may have suffered an internal electronic failure.
Remove the tiller head cover casing. Use electronic cleaner spray to remove dust, debris, or moisture buildup around the sensor cards. Step 2: Test the Sensor Voltage Outputs
The primary cause of error code 4372 has been identified as a firmware bug in the tiller head’s control logic. The original software that ships on some EJE 120 models defines a very narrow "window" of travel for the drive and lift switches before the system registers them as activated. jungheinrich eje 120 error code 4372

The 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.
Often, the electronic zero-point drifts away from the mechanical zero-point. A "teach-in" calibration tells the controller where the true neutral zone sits. Turn on the vehicle using your PIN pad or key switch.
If you can provide the or serial number of your EJE 120, I can offer more tailored troubleshooting steps, including identifying if your unit requires a firmware update . Discussion: Error 4372 - Forums - Forklift Action
