: This typically requires a certified technician with Jungheinrich JUDIT diagnostic software to recalibrate the tiller head and update the firmware. 4. Replacing the Tiller Head Print Card
If a software patch doesn't work, the internal card or the entire tiller head unit might be physically faulty and need replacement.
A: Yes. The error indicates the truck cannot verify the tiller's neutral position. The safety logic will likely cut drive and lift functions. Do not attempt to override it. jungheinrich eje 120 error code 4372 top

The most effective course of action is to contact an authorized Jungheinrich service technician. They can first attempt a firmware update, which is often the only fix needed. If that fails, they can accurately diagnose whether the internal control card requires replacement. By following this structured approach, you can get your material handling operations back up and running with minimal downtime.
For a , error code 4372 (sometimes displayed as E4372 ) typically indicates a missing neutral zone in either the drive or lift/lower functions . This commonly occurs when the controller does not detect a "zero" or "neutral" position from the handle or tiller controls upon startup or during operation. Error Summary Do you have access to a or software interface
The junction connector (usually located under the plastic cowling near the tiller arm pivot point) is exposed to moisture, salt (in cold storage), and dust. Green corrosion on the pins disrupts the 5V reference signal or CAN-High/CAN-Low lines.
| Cause Category | Specific Fault | Probability | |----------------|----------------|--------------| | | Sticking or jammed limit switch roller (S4) | High | | Electrical | Short to ground or open circuit in S4 wiring | Medium | | Alignment | Cam/bracket misalignment due to mast wear or impact | Medium | | Controller | Faulty input on main board (MOSFET or pull-up resistor) | Low | | Hydraulic | Over-lift due to leaking cartridge valve (allows piston past cutoff) | Rare |
Measure the resistance on the signal supply lines while slowly swinging the tiller handle back and forth. Any sudden jump to infinite resistance indicates a broken internal wire that requires patching or replacement. Step 4: Apply Firmware Updates (Software Calibration) Replacing the Tiller Head Print Card If a

On the EJE 120, error 4372 correlates to a "TOP" sensor signal fault . In plain English: The truck’s controller does not see the tiller arm in the correct position to allow travel.
