If a warning light or fault code appears on the instrument panel, what is the correct sequence of actions?

• A. Ignore the warning light and proceed with the task.
• B. Stop safely, identify the code from the display, consult the operator’s manual, and address or report the issue before continuing.
• C. Operate at reduced speed until a technician arrives.
• D. Record the code and continue without stopping.

Answer: (B)

When a warning light or fault code appears, it’s signaling that something may be wrong with the machine and could affect safety or performance. The correct sequence is to stop safely, identify the code from the display, consult the operator’s manual to interpret what the code means and what action is advised, and then address the issue or report it before continuing. Stopping safely prevents exacerbating a potential problem, such as stressing a subsystem or losing stability, while the code and manual together tell you exactly what needs attention—whether it’s a simple check, a component reset, or a service call. If you can resolve the issue per the manual, you may resume operations; if not, document the code and symptoms and have maintenance inspect the machine before proceeding. Ignoring the warning, continuing at reduced speed, or proceeding without stopping can lead to unexpected failures and unsafe conditions.
