Jungheinrich Eje 120 Error Code 4372 Top Guide

The EJE 120 uses a 120-ohm terminating resistor at both ends of the CAN bus (Master controller and Top module).

: Loose sensor cables or worn connectors between the controller and tiller head can cause the error to appear sporadically after movement. Recommended Troubleshooting Steps

| Cause Category | Specific Fault | Probability | |----------------|----------------|--------------| | | Sticking or jammed limit switch roller (S4) | High | | Electrical | Short to ground or open circuit in S4 wiring | Medium | | Alignment | Cam/bracket misalignment due to mast wear or impact | Medium | | Controller | Faulty input on main board (MOSFET or pull-up resistor) | Low | | Hydraulic | Over-lift due to leaking cartridge valve (allows piston past cutoff) | Rare | jungheinrich eje 120 error code 4372 top

The onboard system continually runs a self-test diagnostic loop. Error 4372 surfaces under two conditions:

On the electric pallet truck, Error Code 4372 indicates a tiller head sensor failure caused by an implausible analogue signal or a neutral zone window that is too narrow . When this event message triggers, the vehicle's onboard controller halts specific operational mechanics—frequently cutting out the hydraulic lift and lower functions or preventing travel. The EJE 120 uses a 120-ohm terminating resistor

Error 4372 is defined as: “Top limit switch (S4) – invalid state in relation to lift command or S10 status.” Specifically, the truck’s main controller (CAN-bus based) detects that S4 has changed state without the expected sequence from S10, or that S4 remains open longer than the logic permits.

Prevention is always better than a service call. Error 4372 surfaces under two conditions: On the

: The error frequently occurs when the controller cannot detect a "neutral" position for the drive or lift/lower controls.

The wire harness running down the length of the tiller arm flexes every time the operator steers. Over time, internal wire strands can fray or break, causing intermittent voltage drops that the controller logs as a severe sensor anomaly. 🛠️ Step-by-Step Troubleshooting and Repair Workflow
