Latest update date: February 27, 11

Job car diagnostics has become an essential part of vehicle maintenance and repair. Nowadays, with the development of technology, determining the cause of the problem is not only based on experience but also requires modern equipment and scientific processes.

Early and regular diagnosis can reduce vehicle repair costs by 30-50% and extend vehicle life by 2-3 years.

Here is a detailed guide on how to effectively test and diagnose car faults.

When to check and diagnose automobile errors?

Cars need to be inspected when:

  • Long-term use: If the vehicle has been used for a long time, periodic inspection is necessary to ensure safety and performance.
  • Abnormal symptoms: When there are signs such as warning lights on the dashboard, strange noises or unstable driving feeling.

Car fault classification

Car faults are generally divided into two categories:

  • Permanent faults: These faults are persistent until they are corrected, for example brake lights not working.
  • Random errors: These errors can appear sporadically and be difficult to detect, such as a temperature sensor not working properly.

Car fault diagnosis and testing process

To quickly and accurately determine car faults, you can follow the following procedure:

  • Read vehicle data: Capture parameters such as chassis number, registration date to find appropriate repair documents.
  • Record information from customers: Ask about symptoms and situations where errors occur to narrow down the cause.
  • Visually inspect and listen for noises: Look for unusual signs and listen for sounds coming from the vehicle.
  • Test drive the car: Get a feel for the car's condition while driving to detect potential problems.
  • Read fault memory: Use a diagnostic tool to check fault codes stored in the vehicle's control system.
  • Physical inspection: If the fault cannot be determined from the electronic data, it is necessary to disassemble the components for direct inspection.

Mode of checking the status of cars

How to check car condition:

  • Mechanical Check: Used for faults related to the engine, chassis or drivetrain.
  • Electronic testing: Used for electrical and electronic systems such as lighting systems, engines, or air conditioning systems.

Tools necessary:

  • Car Diagnostic Tool: This device reads fault codes and provides detailed information about the vehicle's condition.
  • Multimeter: Used to check voltage and current in electrical circuits.
  • Oscilloscope: Analyzes electronic signals from sensors or controllers.

Modern technology in car diagnostics

Today, automotive diagnostic technology has made great strides:

  • IoT (Internet of Things) technology: Helps connect repair devices together, allowing remote monitoring of vehicle status.
  • Artificial Intelligence (AI): Supports faster and more accurate data analysis, helping technicians make effective repair decisions.
  • Repair Robots: Perform automation tasks in the repair process, minimizing human errors.

Investing in modern diagnostic systems helps garages save an average of 45% on operating costs and increase repair efficiency by 60%.
