The single biggest mistake operators make is assuming that disconnecting the battery for 10 minutes will clear a hard fault. On a Palfinger , this does nothing. The codes are stored in EEPROM memory. You must use the button sequence (Menu > Diagnostics > Clear) or a dealer laptop.
| Error Code | Description | Immediate Action | | :--- | :--- | :--- | | | Battery voltage below 10.5V (Low voltage lockout) | Check alternator and truck batteries. Jump start or charge. | | 102 | Voltage spike / Over-voltage (>16V) | Regulator failure. Disconnect crane immediately to save ECU. | | 110 | Ground fault at main relay | Clean chassis ground strap. Measure resistance (<0.5 Ohms). | | 115 | Control unit internal power failure | Cycle main power. If persists, ECU replacement required. | palfingercranemanualerrorcodes
This action forces the system to re‑initialise and reset any pending error codes that are not caused by a persistent hardware fault. However, if a physical error still exists (e.g., a broken cable or a defective sensor), the code will reappear immediately. The single biggest mistake operators make is assuming
He tapped the side of the display panel, hoping it was a loose wire. Nothing. You must use the button sequence (Menu >
