Understanding Jungheinrich EJE 120 Error Code 4372 Jungheinrich EJE 120 Safety First: Park the truck on a level

, Error Code 4372 (often displayed as E4372) indicates a Tillerhead Failure, specifically related to an "analogue implausible" signal from the tiller head sensor. This error typically occurs when the system cannot find a clear "neutral zone" for the drive or lift/lower controls, causing the truck to cut out hydraulics or stop travel functions. Primary Causes

Narrow Neutral Zone: The factory-set "window" for the neutral position is too small, leading the sensor to think it is constantly engaged even when it's not.

Sensor Wear or Damage: A faulty card inside the tiller unit or a worn-out traction sensor in the drawbar head can send inconsistent analog signals.

Firmware Bugs: This is a known issue in older EJE/ERE stock where the software requires an update to widen the neutral zone tolerance. Recommended Troubleshooting Steps

If you encounter this code, follow these steps to diagnose and potentially resolve the issue: Inspect the Full Wiring Path

Perform a Truck Reset: Switch the truck off and then back on. In some cases, this temporarily clears the "implausible" signal and allows the truck to work normally for a short period.

Check for Firmware Updates: Because this is a documented software issue, a Jungheinrich service technician may need to update the firmware in the tillerhead to expand the neutral zone "window". Inspect the Tillerhead Internals:

Check for any obvious mechanical backlash in the tiller arm or handle that might prevent it from returning to a true center.

Inspect the wiring and connectors inside the tiller head for signs of humidity or loose connections.

Component Replacement: If firmware updates do not solve the problem, the tillerhead assembly or the internal sensor card typically needs to be replaced.
