: The sensors in the tiller head may not be returning to a true neutral position. If the "window" for what the software considers neutral is too narrow, even a minor physical misalignment can trigger the code.

The is a highly reliable electric walkie pallet jack used in busy warehouses. However, encountering Error Code 4372 will immediately halt operations. When this event message fires, the main controller

When the main traction controller (usually a Curtis or Jungheinrich proprietary inverter) loses communication with the microswitches and sensors inside the control handle, the truck locks down as a safety precaution. This prevents uncommanded movements. Common Causes of the Fault

Using a multimeter, check for smooth voltage changes as you operate the controls. Abrupt jumps can trigger the 4372 error. 3. Contact Jungheinrich for Firmware Update

Check the battery state of charge (SoC) on the dashboard display. Disclaimer: This article is for informational purposes

The modern Jungheinrich EJE 120 utilizes a precise, electronically mapped tiller handle. The main steering and traction controllers rely on tight voltage windows to understand exactly when an operator is requesting travel or hydraulic lift.

Moisture or conductive dust can cross electrical contacts inside the handle. Disconnect the truck's battery. Open the plastic tiller head shroud.
