Before dismantling components, check for basic mechanical obstructions. Discussion: Error 4372 - Forums - Forklift Action
Because this error is frequently caused by a tight neutral zone definition, the most effective fix is to check for firmware updates for the tiller head. jungheinrich eje 120 error code 4372 top
: Jungheinrich has released firmware updates for the tiller head specifically to address this error. The update expands the "neutral window," making the system less sensitive to minor sensor fluctuations. The update expands the "neutral window," making the
Early-generation and mid-production runs of the Jungheinrich EJE 120 shipped with an overly sensitive controller firmware framework. The onboard software expects strict, ideal voltage feedback that real-world warehouse wear and tear cannot consistently sustain. 3. Worn Componentry or Damaged Wiring The update expands the "neutral window
Specifically, triggers when the main traction controller detects an irregular voltage or signal coming from the tiller head sensor. The onboard computer expects a precise neutral-voltage window when the travel throttle or lift switches are at rest. If the signal drifts out of this pre-defined window, the vehicle assumes a component is failing or jammed, and engages a safety shutdown. Common Symptoms
