The intuitive diagnosis method involves identifying faults in agricultural transport vehicles through on-site or road testing, observation, and physical sensation, or by using simple tools. This approach is widely used by operators and maintenance teams because it requires minimal investment and no specialized equipment. When applying this method to diagnose vehicle issues, the first step is to identify the symptoms of the fault—what they are, their characteristics, and any accompanying conditions. Then, proceed from simple to complex, analyzing step by step to reach a conclusion. In short, this method can be summarized in six key steps: ask, observe, listen, smell, touch, and test.
"Ask" refers to gathering information. Before diagnosing any issue, it's essential to understand the situation. This includes knowing the vehicle’s mileage, the road conditions it has been exposed to, recent maintenance history, and whether the failure occurred suddenly or gradually. Without asking questions, the diagnosis may be inaccurate or time-consuming.
"Observe" means visually inspecting the vehicle. For example, checking the color of the exhaust smoke can provide clues about the engine's condition. Combining this with other observations helps determine the overall performance of the machine.
"Listen" involves identifying abnormal sounds. Unusual noises from the engine, transmission, or other components can point to specific mechanical issues.
"Smell" refers to detecting unusual odors, such as burning plastic or oil, which can indicate electrical problems, overheating, or fluid leaks. This technique is especially useful for diagnosing issues in wiring, brake linings, or other friction components.
"Touch" involves feeling for temperature changes, vibrations, or irregularities. By manually checking parts like bearings, joints, or fuel lines, technicians can detect issues such as excessive tightness, misalignment, or oil flow problems.
"Test" means verifying the suspected problem through practical checks. For instance, using the single-cylinder cut-off method to locate engine noise or replacing parts to confirm the faulty component. These hands-on tests help ensure accurate diagnosis.
While these six steps form the foundation of intuitive diagnosis, not all are required for every fault. The approach should be flexible, adapting to the specific situation and type of malfunction. This method remains valuable due to its simplicity, cost-effectiveness, and effectiveness in real-world scenarios.
