Physical degradation within the upper command assembly can generate raw data conflicts. Over time, the internal ribbon cables, wiring harnesses, or the analog sensors underlying the manual control switches crack or fray, resulting in erratic, broken electrical feedback. Step-by-Step Troubleshooting and Diagnostics
If physical checks reveal no clear mechanical issues, the problem is deep within the truck's electronics. You can resolve it using the following targeted techniques: Apply a Firmware Update (The Top Solution)
Run a position "teach-in" routine through the machine interface. Re-centers the zero-voltage coordinate.

For the , error code 4372 identifies a Tillerhead failure , specifically an "analogue implausible" signal from the tiller head sensor . This typically indicates that the neutral zone for the drive or lift/lower functions is too narrow or non-existent. Error Overview Description : Tiller head sensor analogue implausible.
If the hardware is physically defective (e.g., corrosion on the circuit board or a faulty "butterfly sensor"), a firmware update won't help. In this case, the entire "Control Head, Upper Part" (the tiller head assembly) must be replaced.
: The pallet jack may work perfectly for several minutes and then suddenly drop out while traveling or reversing. You can resolve it using the following targeted

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.
: Ensure that the lift, lower, and horn buttons snap back smoothly into place. If any button feels sticky or sluggish, it can trick the analog evaluator into registering an implausible dual command. Step 3: Check Wiring and Voltage Continuity
Error 4372 is defined as: “Top limit switch (S4) – invalid state in relation to lift command or S10 status.” Specifically, the truck’s main controller (CAN-bus based) detects that S4 has changed state without the expected sequence from S10, or that S4 remains open longer than the logic permits.
