The error codes of electric forklifts vary significantly by brand and model. However, the following are relatively common error codes and their possible meanings among some mainstream brands (such as Toyota, Linde, Jungheinrich, Heli, Hangcha, etc.) for reference:
- E01 / B01
- Common Meaning: Battery-related faults (low voltage, abnormal battery pack, charging circuit fault)
- Troubleshooting: Check the battery level and charger connection; ｒｅｐｌａｃｅ the battery if necessary.
- E02 / M02
- Common Meaning: Drive motor faults (overload, short circuit, abnormal encoder)
- Troubleshooting: Stop operation to cool the motor and check the motor wiring harness.
- E03 / C03
- Common Meaning: Controller faults (abnormal mainboard, program error, communication interruption)
- Troubleshooting: Restart the forklift to attempt reset; if ineffective, professional personnel are required to inspect and repair the controller.
- E05 / H05
- Common Meaning: Hydraulic system faults (hydraulic pump overload, excessive oil temperature, abnormal sensor)
- Troubleshooting: Check the hydraulic oil level, avoid overloading during lifting, and cool the hydraulic system.
- E10 / S10
- Common Meaning: Safety system activation (seat switch not closed, emergency stop button pressed, seatbelt not fastened)
- Troubleshooting: Ensure the operator is seated correctly and reset the emergency stop button.
- Linde
- E11: Drive motor overheating
- E23: Steering system fault
- E32: Hydraulic pump motor overload
- Toyota
- 121: Abnormal battery voltage
- 211: Excessive drive motor current
- 332: Operating handle signal fault
- Heli
- Err01: Battery undervoltage
- Err08: Charger connection error
- Err15: Hydraulic limit switch fault
- The specific meaning of an error code must be based on the corresponding forklift's Maintenance Manual; the above is for general reference only.
- When an error code appears, it is recommended to first record the complete code (including letters, numbers, and symbols), then contact the brand's after-sales service or refer to the manual.
- Do not force the operation of a forklift with an error code, as this may expand the fault or cause a safety accident.
