Truck accelerates sluggishly, then cuts power and displays code.
Turn signal or tail light not working. No bulb-out warning on older systems.
No hydraulic functions. The truck may beep continuously.
The truck will not move. You hear a relay click but no release.
Always keep a copy of the official Jungheinrich fault code list near your charging station, and invest in a CanAnalyzer interface if you maintain a fleet of three or more reach trucks. When in doubt, prioritize safety: a truck displaying active error codes should be quarantined until properly diagnosed.
