Bobcat 773 - Code 26-03 Fault Analysis - MikePhua - 07-04-2025
The Bobcat 773 is a commonly used skid-steer loader. Users have reported encountering fault code 26-03 during operation. This code typically indicates an electrical system issue, specifically related to the machine's electronic controls.
What Does Code 26-03 Mean?
According to Bobcat’s service manual, code 26-03 usually refers to a “hydraulic valve solenoid circuit error,” which could be caused by poor wiring connections, loose connectors, or a faulty solenoid valve. This type of electrical issue can interfere with the hydraulic system's operation, affecting the loader's overall functionality.
Troubleshooting Steps
- Check Wiring Connections: First, inspect the wiring between the solenoid valve and the controller to ensure there are no loose or poor connections.
- Inspect the Solenoid Valve: If the wiring appears normal, further investigate the solenoid valve itself. You can use a multimeter to check for proper voltage, or replace the solenoid to see if it resolves the issue.
- Control Module Issue: If the solenoid and wiring are both fine, the problem may lie with the control module. Advanced diagnostic tools may be needed to identify a malfunction in the module.
- Clear the Fault Code: Once repairs are completed, be sure to clear the fault code and restart the machine to check if the issue has been resolved.
Some users have shared their experiences, noting that this issue is often caused by damaged wiring or a faulty solenoid valve. After addressing these components, the machine usually returns to normal operation. Additionally, regular electrical system checks and maintenance can help reduce the likelihood of encountering this type of fault.
Conclusion
When encountering code 26-03 on a Bobcat 773, start by checking the solenoid valve circuit and wiring for any loose connections. If the solenoid is functioning properly, further investigate the control module and other electrical components. Thorough troubleshooting and repairs typically resolve the issue, returning the loader to full operation.
