Jungheinrich Eje 120 Error Code - 4372 Work !!top!!

Check for available factory firmware updates specifically targeting the tiller head parameters.

The wiring harness running down the length of the folding steering arm takes a beating every time the operator maneuvers the jack. Pinched wires, loose terminal connections, or moisture entry can introduce electrical resistance or interrupt the CAN bus communication between the tiller head and the primary traction controller.

Unscrew the housing of the tiller head to access the primary electronic board.

Many units from certain production periods had a firmware bug where the software "window" for the neutral position was too small to account for minor sensor drift.

Jungheinrich released a targeted software campaign to address this specific issue in older models. Discussion: Error 4372 - Forums - Forklift Action

Switch off the key switch or disconnect the emergency battery plug.

Inspect the exterior of the tiller head for trapped debris or physical damage to the control switches.

Note symptoms and conditions

Inspect the internal components for mechanical stickiness. Ensure the springs reliably return the lift, lower, and drive controls back to a perfect, dead-center neutral position.

The electronic "window" defining the physical neutral position of the drive or lift control is too restrictive. If the sensor drifts slightly, the controller throws a 4372 code.
