Signal plausibility mismatch flagged during a specific subsystem request. Verify analog channel tracking via diagnostic software.
Reseat the plug connections on the controller cards to ensure they are not loose. Resolution Strategies
Note : If the fault clears and the truck operates temporarily before tripping again when changing direction, the issue points directly to a software window limit or a failing potentiometer position. Step 2: Clean and Inspect Tiller Head Assembly
If firmware and drying do not work, the sensor on the print card itself may be faulty. jungheinrich eje 120 error code 4372 top
: The wires inside the folding arm bend every time the handle moves. Over time, these wires can crack or fray.
: Inspect the tiller head for loose components, mechanical backlash, or physical damage to the sensors/wiring. Verify Connections
[Tiller Head Sensor] ---> [Analog Signal Out of Range] ---> [Error Code 4372] | | | (No Neutral Zone) (Damaged Wiring) (Hardware Wear) 1. Missing or Narrow "Neutral Zone" Resolution Strategies Note : If the fault clears
Depending on whether the problem is mechanical or electronic, use the following solutions to clear the code permanently: Fix Action Technical Method Primary Goal
The EJE 120 uses a 120-ohm terminating resistor at both ends of the CAN bus (Master controller and Top module).
This error is part of the truck’s event messaging system, where the first two digits usually refer to the function group—in this case, steering and control interfaces. Over time, these wires can crack or fray
A: A recurring, unresolved error code can negatively impact resale value. Having the truck professionally serviced and the firmware updated provides documentation that the issue is resolved, which is a positive selling point.
In 90% of cases, the issue is not a major mechanical breakdown but rather an overly sensitive neutral zone sensor in the tiller head, resolvable with a simple from a qualified technician. If the problem persists, a replacement of the tiller head control card will return the EJE 120 to full operation.
