Introduction
The 940E Mustang skid steer loader, a reliable machine in various construction and landscaping applications, has been facing an intermittent control lock-out issue, frustrating operators and causing delays. The problem occurs when the control lock-out feature is engaged unexpectedly, preventing normal operation. This article discusses the potential causes of the intermittent lock-out issue, possible solutions, and troubleshooting steps that can help resolve the problem.
Understanding the Control Lock-Out Feature
The control lock-out feature on a skid steer loader like the 940E Mustang is designed to prevent accidental movement of the machine when not in use or during maintenance. This feature locks the hydraulic system to ensure safety by preventing unintentional activation of the controls. However, when it becomes faulty or engages unexpectedly, it can cause significant downtime and hinder the operator's ability to perform tasks effectively.
Identifying the Problem
The issue with the 940E Mustang manifests as the control lock-out engaging intermittently, often without warning. The machine may become unresponsive to operator inputs, and the usual solution is to reset or toggle the lock-out system. The cause of this issue can be traced to several possible factors, which include:
If your 940E Mustang is experiencing intermittent control lock-out issues, here are the key troubleshooting steps you can follow:
To minimize the risk of encountering similar issues in the future, it is crucial to perform regular maintenance on the 940E Mustang. Some tips include:
The intermittent control lock-out issue in the 940E Mustang can be frustrating, but by systematically troubleshooting the electrical and hydraulic systems, checking relays and solenoids, and performing necessary repairs, operators can quickly resolve the problem. Regular maintenance and awareness of the system’s functionality can also prevent such issues from recurring in the future.

The issue with the 940E Mustang manifests as the control lock-out engaging intermittently, often without warning. The machine may become unresponsive to operator inputs, and the usual solution is to reset or toggle the lock-out system. The cause of this issue can be traced to several possible factors, which include:
- Electrical System Issues:
The control lock-out system is often controlled by the electrical system, with sensors and switches responsible for detecting whether the lock-out should be engaged. A faulty sensor, loose wiring, or a malfunctioning switch could cause intermittent failures, leading to the unexpected activation of the lock-out.
- Hydraulic Pressure Problems:
The lock-out system is closely tied to the hydraulic system. Low hydraulic pressure or issues within the hydraulic valves could cause the control to lock-out unexpectedly. This is often the case if the system is not providing sufficient pressure for the machine to operate as intended.
- Faulty Relays or Solenoids:
Electrical relays or solenoids responsible for the control lock-out mechanism could be malfunctioning. A faulty relay may intermittently send a signal to lock-out the controls, preventing proper operation.
- Software or Control System Glitch:
In modern skid steers like the 940E, software glitches or issues within the control system could lead to faulty lock-out behavior. A system reset or software update may be required to resolve these issues.
If your 940E Mustang is experiencing intermittent control lock-out issues, here are the key troubleshooting steps you can follow:
- Check Electrical Connections:
Inspect the wiring, sensors, and switches connected to the control lock-out system. Look for signs of wear, corrosion, or loose connections. Ensure that all components are securely connected, and replace any faulty parts.
- Inspect the Hydraulic System:
Check the hydraulic fluid levels and pressure. If the pressure is too low, the system might not be able to disengage the lock-out properly. Ensure there are no leaks in the hydraulic lines, and consider checking the hydraulic pump if the problem persists.
- Test the Relays and Solenoids:
Use a multimeter to test the electrical relays and solenoids involved in the control lock-out mechanism. Replace any defective components to restore proper function.
- Perform a System Reset or Software Update:
In cases where the issue is related to the control system or software, consult the operator’s manual to perform a system reset. Additionally, check with the manufacturer for any available software updates that could fix potential bugs or glitches in the system.
- Consult the Operator’s Manual:
The operator's manual for the 940E Mustang may provide additional troubleshooting guidance. Be sure to follow all safety precautions while troubleshooting to prevent injury or further damage to the machine.
To minimize the risk of encountering similar issues in the future, it is crucial to perform regular maintenance on the 940E Mustang. Some tips include:
- Regularly Inspect Electrical Components:
Periodically check the wiring, sensors, and switches for any signs of wear or damage, and address any issues promptly.
- Monitor Hydraulic Pressure:
Regularly monitor and maintain hydraulic pressure to ensure that the system is functioning properly.
- Keep the Machine Clean:
Clean the electrical and hydraulic components to prevent debris buildup, which can cause malfunctions.
- Consult with a Technician:
If you're unable to resolve the issue yourself, don't hesitate to seek professional help from a certified technician. Regular inspections by professionals can help catch issues before they cause major downtime.
The intermittent control lock-out issue in the 940E Mustang can be frustrating, but by systematically troubleshooting the electrical and hydraulic systems, checking relays and solenoids, and performing necessary repairs, operators can quickly resolve the problem. Regular maintenance and awareness of the system’s functionality can also prevent such issues from recurring in the future.
