Jungheinrich Eje 120 Error Code 4372 [updated]

Some instances of this code are triggered by transient electrical issues. A simple restart of the truck may temporarily clear the code and return it to normal operation, though the underlying sensor issue usually persists.

Execute the calibration routine: move the throttle fully forward, fully backward, and then let it snap back into neutral. Save the target and actual values to clear the fault. 3. Check the Tiller Arm Wiring Harness

Error code 4372 signals a fault.

Measure voltage across the battery terminals with no load (should be >24V). Then, activate the lift function while measuring. If voltage drops below 20V during lift attempt, before proceeding further. jungheinrich eje 120 error code 4372

You will rarely see the code appear without other noticeable symptoms. These include:

Use a multimeter to perform a continuity test on the CAN-Hi, CAN-Low, positive power, and ground wires running through the arm. 3. Inspect Connectors and Clean Terminals

In some cases, particularly with older or heavily worn units, the hardware itself may be compromised. As noted in one forum discussion, the only way to fix the error could be to "replace the printcard [circuit board] in steering head". If the neutral zone "window" expansion doesn't work or if the sensors are physically failing, the entire upper tiller head assembly may need to be replaced.
