Scan Tool Diagnostic: The Smart Way to Identify Vehicle Problems Early

Today’s cars are smarter than ever before. These days, electronic control units (ECUs) are controlling all aspects of car performance from engine management to safety systems. If a problem occurs, your car may be storing some useful information that can help you pinpoint the issue in no time. That’s where scan tool diagnostic come in handy.

So, when a warning light or strange behaviour occurs, instead of guessing at the cause, the professional diagnostic equipment can speak directly to the computer systems of your vehicle to pinpoint the problem. This not only saves time, but reduces needless repairs and assists the technicians in identifying the actual problem.

Luca Motors offers professional scan tool diagnostics, using top-of-the-line diagnostic equipment for all major makes and models, throughout Alphington. If your Check Engine Light has come on, or if your vehicle doesn’t seem to be running like it used to, our trained technicians are able to pinpoint the issue and suggest the best fixes.

In this guide, you will learn about the process of scan tool diagnostics, when you should have a diagnostic check, and how you can save yourself money by detecting problems early.

What Are Scan Tool Diagnostic?

Scan tool diagnostics use a special OBD Vehicle scan tool to connect to your vehicle’s On-Board Diagnostics (OBD) port.

The scanner can access your vehicle’s electronic control modules to retrieve stored fault codes, live performance data and system information.

A diagnostic scan can test a variety of systems, such as:

Modern diagnostic tools offer valuable information to help technicians quickly identify faults.

Why Are Vehicle Diagnostics Important?

Modern cars have a dozen or more electronic sensors.

Even minor defects can impact the vehicle’s performance, fuel economy, emissions and safety.

Professional diagnostics help:

Preventing bigger mechanical failures later means that problems can be addressed early.

Common Signs Your Vehicle Needs Scan Tool Diagnostics

Various warning signs should tell you it’s time to call in the professional inspection.

Check Engine Light

The most frequent diagnostics booking is for an engine warning light.

Fault codes may be present in the vehicle even when the car looks like it is driving normally.

Poor Fuel Economy

If changing the oil more frequently than normal, it may be sensor problems or problems with the engine management system.

Rough Idling

If an engine is shaking or is operating unevenly, it should always be investigated.

Difficulty Starting

Difficulty in starting can be caused by issues with sensors, fuel delivery, ignition or battery management.

Loss of Power

The reason for poor acceleration is due to some electronic or mechanical fault.

Diagnostic testing is used to determine the exact cause.

Warning Lights on the Dashboard

Today’s cars track a variety of systems such as:

Don’t ignore warning lights, as it can result in more costly repairs.

How Does Scan Tool Diagnostics Work?

Professional vehicle diagnostics follow a systematic process.

Connect the Diagnostic Scanner to the USB port.

Step 1: Plug the Diagnostic Scanner into the USB port.

The tech places a professional scan tool in your vehicle’s OBD port.

In step 2, retrieve Fault Codes.

The scanner reads the vehicle’s diagnostic trouble codes (DTCs) that are stored in the vehicle’s computer.

The next step is to analyse live data (Step 3).

Technicians check live sensor readings, such as:

This information allows technicians to detect intermittent faults.

Next, conduct more tests (Step 4).

In some cases, fault codes do not provide enough information to pinpoint the malfunctioning part.

Further testing is done by experienced technicians if it is required.

Step 5 – Recommend Repairs

Once identified, you’ll get a thorough diagnosis, repair advice and an estimate.

Problems Scan Tool Diagnostics Can Detect

There are lots of problems that can be detected with professional diagnostic equipment.

These include:

Diagnosing early can prevent further damage.

Why Professional Diagnostics Are Better Than Basic Code Readers

There are lots of cheap code readers on the web.

Typically, they are only able to give a basic fault code and do not identify the actual fault.

Professional scan tools offer:

Professional scanners offer much greater precision over DIY scanners.

Benefits of Early Diagnostic Testing

Delays up to a point of critical fault severity can lead to higher repair costs.

The benefits of early diagnosis are numerous.

These include:

The repairs are generally more cost-effective for small issues rather than large mechanical issues.

How Often Should Vehicle Diagnostics Be Performed?

Do not need to use a warning lamp.

It’s worth having a diagnostic inspection if:
