A: No. This is a protective code. Bypassing it (e.g., by jumpering the lift contactor) can destroy the lift motor or cause a battery explosion. Do not attempt.
Error code on a Jungheinrich EJE 120 (and related models like the ERE 225) primarily indicates a Tillerhead failure related to the neutral zone . This common issue typically prevents the truck from operating travel or hydraulic functions because the tiller head sensor cannot find a valid "neutral" or zero position. Root Cause: Narrow Neutral Zone jungheinrich eje 120 error code 4372 work
Manufacturers balance concise codes (compact for displays) with detailed internal diagnostics. A 4-digit code like 4372 is efficient for technicians who have manuals or service tools, but for floor operators it becomes a puzzle that points to deeper systems thinking — electrical, software, mechanical, and environmental causes all intersect. Do not attempt
Specialised services, such as EKT TEKNOLOJİ , offer repair and revision services specifically for Jungheinrich E4372 fault codes, which may involve repairing the internal control boards or cards.

: Ensure the drive and lift/lower controls return fully to their neutral positions; if they stick, the controller may trigger 4372 because it sees conflicting signals. Forkliftaction Technical Breakdown of Jungheinrich Codes Jungheinrich uses a four-digit system to categorize errors: First Digit (4) : Typically refers to the Display/Interface or specific logic groups. Following Digits (372)
If a software update doesn't solve it, or if the sensor inside the tiller head is physically failing, the standard mechanical fix is to replace the tiller head unit . Some forum discussions, such as those on Forklift Action , suggest this is a "plug and play" fix, though diagnostic software may be needed for certain configurations.
