Bobcat Telehandler Fault Codes (Error Code List for Telescopic Handlers V, T, TR, TL Series)

Bobcat Telehandlers, such as the TL25, TL26, TL30, TL34, T35, TL35, T36, TL38, T40, T41, TL43, TR50, TR60, TR80, TL519, TL619, TL723, and TL923 models, are robust and versatile machines designed for a variety of lifting and material handling tasks. To ensure these machines operate efficiently and safely, they are equipped with advanced diagnostic systems that monitor various components and systems in real-time. When a problem is detected, the telehandler’s control system generates fault codes that help operators and technicians identify and address issues promptly.

Bobcat Telehandler Service Codes

Fault codes are alphanumeric indicators that correspond to specific errors or malfunctions within the telehandler. These codes can provide insight into problems ranging from minor sensor issues to significant mechanical failures. By understanding and interpreting these codes, operators can perform timely maintenance, prevent extensive damage, and minimize downtime.

Bobcat Telehandler Error Codes

Fault codes alert operators to potential problems before they escalate into serious issues, allowing for proactive maintenance. Addressing fault codes promptly can prevent accidents and ensure the telehandler operates safely.

Bobcat Telehandler Error Codes

Early identification and resolution of faults can save on costly repairs and extend the lifespan of the telehandler. Keeping the telehandler in optimal condition ensures it performs efficiently, reducing fuel consumption and wear and tear on components.

Bobcat Telehandler Errors

Fault codes on Bobcat Telehandlers cover a wide range of issues, including engine performance, hydraulic systems, electrical components, and more. Each fault code consists of a numerical part that identifies the system or component and a description that provides details about the nature of the problem.

How to Retrieve Bobcat Telehandler Fault Codes

To retrieve fault codes, operators typically use the machine’s display screen or control panel, navigating to the diagnostics menu where codes are listed along with their descriptions.

Bobcat Telehandler Diagnostic Service Codes

Once a fault code is identified, the operator can refer to the telehandler’s manual for troubleshooting steps or seek assistance from a certified Bobcat technician.

  1. Ignition Key Position: Turn the ignition key to the “On” position, but do not start the engine. This powers up the control system and display screen.
  2. Accessing the Diagnostics Menu: Use the control panel or display screen to navigate through the menu options. Look for options labeled “Diagnostics”, “Fault Codes”, or similar. This can often be accessed using directional buttons or a specific combination of buttons, depending on the model.
  3. Viewing Fault Codes: Once in the diagnostics menu, select the option to view fault codes. The screen should display a list of any active fault codes along with descriptions or error messages.
  4. Recording the Codes: Write down the fault codes displayed. These will be alphanumeric codes that correspond to specific issues. Note any additional information or descriptions provided on the display.
  5. Consulting the Manual: Refer to your Bobcat Telehandler’s user manual or service manual for the detailed meaning of each fault code. The manual will provide explanations and suggested actions for each code.

Based on the fault codes and their descriptions, take the necessary steps to address the issues.
