The circuit board inside the tiller head (responsible for throttle, lift, lower, and horn signals) may have suffered an internal electronic failure.
Check the battery state of charge (SoC). Ensure the battery reads a healthy voltage (typically above 24V for a 24V system) and that the terminals are clean and tight.
: If software updates and cleaning do not resolve the issue, the tiller head sensor or the internal control card may be faulty and require replacement. Forkliftaction service manual for the Jungheinrich EJE 120 to help with the repair? Discussion: Error 4372 - Forums - Forklift Action
: Internal wiring harnesses running up the tiller arm can fray, pinch, or loose connection, sending chaotic or implausible voltage spikes to the drive controller. Step-by-Step Diagnostic & Repair Guide jungheinrich eje 120 error code 4372
The EJE 120 has a limit switch that detects when the forks reach maximum lift height. If this switch fails in the closed (activated) position or sends an intermittent signal, the controller thinks the forks are at the top even when they are down, leading to a plausibility error when you try to lift.
The brake coil is an electromagnet. Over time, the winding insulation can break down, causing a partial short circuit (low resistance → too much current) or an open circuit (infinite resistance → zero current). Both trigger a plausibility error.
If your EJE 120 was purchased from older stock, it may be part of a previous Jungheinrich campaign to replace or update these specific tiller units. local Jungheinrich service center to check if your truck's firmware is up to date?

The first and easiest step is to perform a full restart. Turn the key switch to the "O" (off) position, wait for the dashboard to complete its shutdown cycle, remove the key, and wait approximately 30 seconds. Turn the key back to the "I" (on) position and allow the truck to complete its boot cycle. If the error was a one-time glitch, this might clear it temporarily. However, if the firmware bug is present, the code will almost certainly reappear.
Because resolving this code often requires specialized diagnostic software like , it is recommended to contact an authorized Jungheinrich Service Center if basic restarts and wiring checks do not clear the fault. Discussion: Error 4372 - Forums - Forklift Action

: Switch the truck off and then back on again. In some cases, this clears minor signal glitches and allows the system to recalibrate its zero-point.
