Jungheinrich error codes are typically five digits long, with the first digit often indicating the general component area. The 4372 error provides information about a problem concerning the tiller's neutral zone and sensor plausibility.

A certified technician will perform a "Bus Load Analysis" to see if another module (like the drive motor encoder or lift pump controller) is flooding the CAN bus with noise, causing the Top module to be ignored. Burned logic components on the controller boards corrupt

on a Jungheinrich EJE 120 pallet jack means the tiller head sensor signal is implausible . When this happens, the truck’s computer gets a confusing signal from the handle. The truck cannot tell if you are trying to move, lift, or stay in neutral.
