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) jungheinrich eje 120 error code 4372 top

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: : If sensors have been replaced or moved,

Before calling for a costly service technician, check these three primary culprits: This area is subject to constant flexing and

The controller detects that there is no neutral zone (zero-travel position) for the drive or lift/lower functions. This can be caused by physical wear, electrical drift, or outdated firmware that has a "neutral window" that is too narrow to accommodate normal sensor aging. Secondary Causes: Faulty traction or steering sensors within the tiller head. Damaged or loose wiring in the tiller head harness.

This issue often occurs when the truck’s control system detects that the sensor is not in its "neutral" or "zero" position during startup or operation, which can cause the hydraulics to cut out.
