How Do You Diagnose and Fix Error 58 on Forklifts?
Error 58 on forklifts commonly indicates a fault related to the bearing sensor inside the steering motor or worn rim bearings near the gearbox or drive motor, which can block steering motor force. Proper diagnosis and timely repair of these components are essential to restore safe and efficient forklift operation.
What Does Error 58 Mean on a Forklift?
Error 58 generally signals a problem with the brake coil or steering motor bearing sensor. It may reflect mechanical wear, sensor failure, wiring issues, or electrical faults that affect braking or steering functions.
How Do You Diagnose the Cause of Error 58?
- 
Inspect the bearing sensor inside the steering motor for faults. 
- 
Check the rim bearing above the gearbox or underneath the drive motor for wear or damage. 
- 
Test brake coils for correct resistance (typically around 46 ohms). 
- 
Examine wiring harnesses and connectors for corrosion or damage. 
- 
Use diagnostic tools to read error codes and live data. 
- 
Verify battery voltage and electrical system health. 
Which Components Should Be Checked When Error 58 Occurs?
- 
Steering motor bearing sensor. 
- 
Rim bearings near the gearbox and drive motor. 
- 
Brake coil and brake module. 
- 
Wiring and connectors related to steering and braking. 
- 
Battery and contactor circuits. 
Why Is Bearing Sensor and Rim Bearing Condition Important?
Worn or faulty bearings can cause mechanical blockage, increasing load on the steering motor and triggering error codes. Bearing sensors monitor motor conditions and help prevent damage by signaling faults early.
How Can You Test Brake Coils and Related Electrical Components?
- 
Measure coil resistance with a multimeter; typical value is about 46 ohms. 
- 
Inspect brake module wiring and connections. 
- 
Check battery voltage to ensure sufficient power. 
- 
Replace faulty coils or wiring as needed. 
When Should You Replace Bearings or Sensors?
Replace bearings or sensors if:
- 
Physical wear or damage is evident. 
- 
Diagnostic tests confirm sensor failure. 
- 
Error codes persist after electrical repairs. 
- 
Steering or braking performance is impaired. 
Where Can You Find Official Forklift Service Manuals and Support?
- 
Authorized forklift dealers and service centers. 
- 
Manufacturer technical documentation and wiring diagrams. 
-
