Look for visible signs of pinching, twisting, or fraying, especially near the pivot articulation joint where bending is most severe.
Specialised services, such as EKT TEKNOLOJİ , offer repair and revision services specifically for Jungheinrich E4372 fault codes, which may involve repairing the internal control boards or cards.

On many legacy configurations of the Jungheinrich EJE 120 (and related models like the EJD 20 or ERE 20), the factory steering map software contained an overly strict neutral threshold. Because the window was so tight, even a tiny millimeter variance in the tiller head assembly caused the truck to believe it was actively trying to drive when it should have been resting, triggering an immediate shutdown. 2.

Several factors can disrupt the analogue signal stream between the tiller head and the primary combi-controller:
Check the return springs on the lift and lower buttons. If the buttons sag or do not snap back sharply into neutral, the sensor reads a constant micro-voltage, throwing code 4372. 3. Check Wiring Harness and Connections Look for visible signs of pinching, twisting, or
Jungheinrich is aware of this issue and has released a firmware update to resolve it. This update expands the neutral zone window, making the sensor less sensitive to slight variations in the tiller position.
On a , encountering Error Code 4372 indicates a tiller head neutral zone failure . This specific fault occurs when the vehicle's controller detects an implausible steering map window or an overly narrow neutral zone in either the drive or the lift/lower controls. When the truck throws this error, the onboard system halts operation as a safety precaution, disrupting warehouse productivity until the issue is addressed. Because the window was so tight, even a
Turn the key switch to the "OFF" position and press the emergency stop (red mushroom button).
Error code on a Jungheinrich EJE 120 refers to a tiller head sensor failure , specifically indicating that the "analogue signal is implausible". This common fault typically means the control unit is receiving conflicting or out-of-range signals from the traction (butterfly) sensor. Core Cause: Neutral Zone Issues
Switch off the key switch or disconnect the emergency battery plug.
