What Is Auto Expertise and Why Is a Diagnostic Tool Important for It?

The word "expertise" comes from the French term "expert". In everyday use it refers to a person with technical knowledge in a specific field.

Auto expertise means skilled technicians examining vehicles in detail with diagnostic tools and test equipment and reporting their findings.

Systems Checked During Auto Expertise

Engine test: engine power, wear level and overall condition are assessed.

Paint and bodywork: with diagnostic tools, test equipment and expert technicians, paint, body panels, replaced parts, repainted sections and accident history are checked.

Engine power (torque) measurement: shows how much power the engine produces at each RPM on a graph. If any revision or modification was done, before and after values are compared.

Handbrake test:

• Maximum left and right brake force measurement
• Wheel contribution measurement by braking intensity
• Left and right wheel difference percentage calculation
• Brake percentage calculation by braking intensity
• Optional hand force measurement
• Brake system adequacy check based on vehicle weight

Suspension test: reveals whether the vehicle suspension is adequate. The test consists of five stages:

• Minimum grip force of all four wheels
• Minimum grip frequency
• Test according to Eusama standards
• Weight measurement of each wheel
• Total vehicle weight measurement

The Importance of a Diagnostic Tool

Today's cars have multiple electronic control units, so finding faults in those units is difficult and time-consuming without the right equipment.

Technology now helps us in almost every area of life, including automotive service.

Among automotive test products, diagnostic tools communicate with control units on the vehicle, evaluate their data and identify the faulty ECU or component directly.

The tool combines with the user's knowledge, guides the operator and saves valuable workshop time.

When buying a used car, sellers often roll back the odometer (km) on high-mileage vehicles to make a sale.

This is a common problem. To prevent it and verify original mileage, you can use diagnostic tools.

Expertise companies and dealers can read km and other fault information with diagnostic tools to serve customers honestly.

Most importantly, keeping up with the growing automotive sector by improving your skills and business is key to staying competitive and profitable.

For example, if you cannot find and fix a fault on a vehicle in your workshop and another technician resolves it with a diagnostic tool, that customer may never return. Customer loss happens in many similar situations.

To avoid this, you need a diagnostic tool in your workshop. You can repair vehicles faster, deliver quality service and grow your customer base.

A diagnostic tool belongs on every workshop equipment list. If you want to improve your business, serve customers well and earn more, we recommend using one.
