Introduction
Most modern Jungheinrich trucks require the proprietary Judit Diagnostic Software for a permanent fix.
- Fix: Check the 6- or 8-pin connector at the top of the drive motor. Look for bent pins, corrosion, or moisture. Unplug, clean with dielectric grease, and reseat firmly.
9. Conclusion
Error 4372 on the Jungheinrich EJE 120 is rarely a controller failure; over 90% of cases are resolved by replacing or adjusting the S4 upper limit switch or its actuator cam. The code is designed to prevent mast over-travel and must be addressed promptly to restore full lift and travel functionality. Using the systematic diagnostic approach outlined above, a qualified technician can resolve the issue in under 90 minutes, avoiding unnecessary component replacement and downtime.
If the error returns immediately, you have a hard fault (broken switch or wire) that requires parts.
Disclaimer: Always consult your specific truck’s operating manual and adhere to safety guidelines. If you are unsure about electrical repairs, consult a professional.
