Jungheinrich Eje 120 Error Code 4372 [2021] [UPDATED]

Understanding Jungheinrich EJE 120 Error Code 4372 Jungheinrich EJE 120

Important Notes

• Open circuit or short circuit on the CAN-High or CAN-Low wires running from the battery socket to the controller.
• Damaged wiring harness (often pinched near the battery compartment or mast).

Check Wiring and Connections

: Inspect the harness and connectors inside the tiller head. Loose or corroded wires can cause the analogue signals to become "implausible" to the controller. jungheinrich eje 120 error code 4372

1. Faulty Electromagnetic Brake Coil

Disconnect the resolver connector (usually a 6-pin AMP/Tyco connector near the motor). Set multimeter to Ohms. Measure: Open circuit or short circuit on the CAN-High

Recalibration (Teach-In)

: 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 Wiring and Connections : Inspect the harness

Wider Neutral Window:

This is a common problem with certain "steering maps." Technicians often resolve this by performing a software update that expands the neutral window, giving the sensor more "room" to be in neutral without triggering an error .
