What Are the Common Methods for Automobile Fault Diagnosis?
1 Answers
Automobile fault diagnosis methods are as follows: 1. Visual and Inquiry Method: When diagnosing a car fault, the repair personnel should first make a preliminary judgment on the car model and usage period upon seeing the car. The model can be identified from its appearance; the usage period can be estimated by observing the exterior or flipping the cab to expose the engine. Experienced repair personnel can even immediately determine the car fault. 2. Experience Method: As the name suggests, the Experience Method relies on the basic skills and extensive experience of drivers and repair personnel to quickly and accurately diagnose car faults. 3. Observation Method: The Observation Method involves the car repairer carefully observing the fault phenomenon at the location indicated by the car user and then making a judgment on the fault. This is one of the most commonly used, basic, and effective fault diagnosis methods. 4. Auditory Method: Using hearing to diagnose car and engine faults is the most common and simple method. When the car is running, the engine operates under different conditions, producing a noisy but regular sound. When a fault occurs in a certain part, abnormal sounds will appear. Experienced individuals can immediately determine the car fault based on the abnormal sounds. 5. Test Method: Using the Test Method to diagnose car and engine faults is one of the common methods. It can be used to check the functions of the car and engine without or with minimal disassembly, achieving the purpose of fault diagnosis.
