: Check for physical obstructions in the tiller handle that might prevent the controls from returning fully to the neutral position.
: The sensors in the tiller head may not be returning to a true neutral position. If the "window" for what the software considers neutral is too narrow, even a minor physical misalignment can trigger the code.
Because resolving this code often requires specialized diagnostic software like , it is recommended to contact an authorized Jungheinrich Service Center if basic restarts and wiring checks do not clear the fault. Discussion: Error 4372 - Forums - Forklift Action jungheinrich eje 120 error code 4372
: The analog signal from the traction or hydraulic sensor in the drawbar head may be abnormal or "implausible" to the main controller.
: If the sensors are functioning but out of alignment, a "Teach-In" process using factory software may be required to redefine the travel and hydraulic limits. : Check for physical obstructions in the tiller
: If calibration fails, you may need to replace the entire tiller head assembly or the specific faulty analog sensor. Professional Assistance
: Older EJE 120 models often have steering maps with narrow neutral tolerances. Jungheinrich has released firmware updates specifically to widen this neutral "window" and resolve persistent 4372 errors. : If calibration fails, you may need to
: Since this is a known issue for many Jungheinrich EJE 120 models, the most effective long-term fix is often a software update using the Jungheinrich Judit diagnostic tool. This update expands the neutral zone, making the truck less sensitive to minor sensor deviations.
: Open the tiller head and inspect the wiring harness for signs of wear or broken connectors. Use a multimeter to verify signal continuity if necessary.
