Jungheinrich Eje 120 Error Code 4372: Top Fixed

In cases of severe internal damage or unresolvable wiring issues, the entire tiller head assembly may be replaced. Summary Table: Jungheinrich 4372 Potential Issue Tiller Head Sensor signal out of range Recalibrate using Judit Software . Firmware Neutral zone too narrow Update firmware to expand the neutral "window". Wiring Broken or pinched wires Inspect tiller arm harness for continuity. Sensors Physical failure Replace traction or steering sensors.

Ensure the tiller handle and all control buttons (butterfly switches) move freely and are not physically stuck or gritty. jungheinrich eje 120 error code 4372 top

Inspect the wiring harness that runs through the tiller arm. This area is subject to constant flexing and is a common point for wire fatigue or shorts. 2. Software Calibration (Requires Judit Diagnostic Tool) In cases of severe internal damage or unresolvable

Jungheinrich has released updates specifically for this error that expand the neutral "window" . This allows the controller to accept a slightly wider range of values as "neutral," preventing the error from triggering due to minor sensor drift. Wiring Broken or pinched wires Inspect tiller arm

Most modern Jungheinrich trucks require the proprietary Judit Diagnostic Software for a permanent fix.

A mechanical issue causing "backlash" or play that prevents the sensor from returning to a true neutral state. 1. Immediate Restart and Physical Inspection

A technician can perform a "Teach-In" to recalibrate the actual values for the direction and travel potentiometers. 3. Component Replacement If calibration fails or the error returns immediately:
