Jungheinrich Eje 120 Error Code 4372 Top Jun 2026
: If calibration fails, the Tiller Head Control Card or the specific potentiometer may need to be replaced. Maintenance Tips
Jungheinrich EJE 120 , error code (often displayed as ) specifically points to a Tillerhead failure
On Jungheinrich’s proprietary diagnostic scale, error codes follow a logical structure. Code 4372 falls under the category of with a specific peripheral device. jungheinrich eje 120 error code 4372 top
The system checks for "analog plausibility." If the signal from the sensor does not match the expected value (e.g., the controller sees both the forward and reverse positions engaged simultaneously or sees an invalid voltage range), the error code 4372 will appear. In many cases, the internal printed circuit board (PCB) inside the tiller head card is defective. One technician bluntly noted, "Only way [is to] replace the printcard in steering head".
Because this issue heavily impacted both standard pallet trucks and ride-on units like the ERE series, Jungheinrich engineering groups issued dedicated service campaigns to address the software logic. Units running legacy firmware lack the adaptive filtering needed to process slight analog variance. 3. Physical Wear and Signal Contamination : If calibration fails, the Tiller Head Control
If firmware and drying do not work, the sensor on the print card itself may be faulty.
Periodically reset the service interval or perform a system reset by switching the truck off and on to clear temporary communication glitches. Discussion: Error 4372 - Forums - Forklift Action The system checks for "analog plausibility
: Older firmware has a very tight "window" for what it considers a safe neutral signal. If the switch shifts by a millimeter, the truck throws an error. Step-by-Step Troubleshooting Guide
