The contactor that sends power from the battery to the lift pump motor can have pitted or welded contacts. A high-resistance contactor will pass enough voltage for diagnostics, but under load (lifting), the voltage collapses.
Multimeter (with continuity/diode mode), Jungheinrich service software (if available), basic hand tools. jungheinrich eje 120 error code 4372 work
Brief context: the Jungheinrich EJE 120 is a common electric pallet truck/stacker model. Error codes on industrial trucks like this point to specific subsystems (battery, motor controller, sensors, CAN bus, safety interlocks). Code 4372 isn’t a universal standard, so we read it like an engineer: decode probable subsystem, failure mode, and practical next steps — plus a few interesting angles on why such faults matter in real operations. The contactor that sends power from the battery
or the tiller arm sensor unit itself may need replacement. For further technical assistance, you can consult the official Jungheinrich Service Portal with your vehicle's serial and order numbers.

This error is frequently reported when there is no clear neutral zone detected in the tiller head components. While a restart might temporarily clear the fault, it often recurs during operation.
: Often, the most effective solution isn't a wrench, but a laptop. Jungheinrich released a firmware update for the tiller head specifically to expand this "neutral window," making the sensor less sensitive to tiny movements or wear. The Hardware Swap
