Jungheinrich Eje 120 Error Code 4372

Many EJE 120 units manufactured around 2017 to 2020 left the factory with early firmware iterations prone to this specific calibration error.

On Jungheinrich electric pedestrian pallet trucks—such as the , EJE 220 , and ERE 225 series—the code E4372 points directly to a tiller head calibration or hardware failure .

Use electrical contact cleaner or compressed air to blow out dust, dirt, or debris around the control switches and sensor wheels. jungheinrich eje 120 error code 4372

Error Code 4372 is fundamentally an analytical or communication error. The pallet jack’s central control unit continuously monitors inputs from the tiller head handle. If those signals contradict standard operating parameters, the truck throws this code. The error generally stems from three primary issues:

Move the paddles fully forward, fully backward, and return to neutral when prompted by the software to map the maximum and minimum voltage boundaries. Step 4: Apply the Official Jungheinrich Firmware Update Many EJE 120 units manufactured around 2017 to

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.

The wiring harness runs from the main chassis up through the pivoting arm of the tiller head. Because this arm constantly moves up, down, and sideways during daily operation, the wires inside the harness experience high mechanical stress. Over time, wires can fray, break, or short-circuit. 2. Loose or Corroded Connectors

Ensure there is no physical debris or damage preventing the tiller handle or lift/lower buttons from returning fully to their home positions .

Pallet jacks frequently operate in harsh environments, including cold storage, damp loading docks, or dusty warehouses. Moisture and debris can penetrate the electrical plugs inside the tiller arm or the main compartment, leading to pin corrosion or loose physical connections. 3.
