Auto Diagnostic Services

Computerizing a car’s components has been one of the technological developments in the automotive industry over the years that’s proved to be the most advantageous to consumers and auto mechanics alike.

What Is A Car Diagnostic Test? 

A car diagnostic test is a process that involves using specialized equipment to scan a vehicle’s onboard computer system to identify and diagnose any potential issues or malfunctions.

The onboard computer system, known as the engine control module (ECM), constantly monitors various sensors and systems in the vehicle, such as the engine, transmission, brakes, and emissions.

A diagnostic test can reveal any issues with these systems and help pinpoint the root cause of the problem. The results of a diagnostic test can be used to guide necessary repairs and maintenance, ensuring that the vehicle is operating at optimal performance and efficiency.

How Does It Work? 

A car diagnostic test typically involves connecting a specialized scanner or diagnostic tool to the vehicle’s OBD-II (On-Board Diagnostics) port, which is usually located under the dashboard on the driver’s side.

The diagnostic tool communicates with the vehicle’s ECM and retrieves any stored trouble codes, which are unique codes that indicate the source of the problem. The codes can provide valuable information about various systems in the vehicle, such as the engine, transmission, emissions, and more.

Once the codes are retrieved, a skilled technician will use their expertise to analyze the data and identify the underlying issue. This information can help guide necessary repairs and maintenance, ensuring that the vehicle is operating at optimal performance and efficiency.

Why Is It Important? 

A diagnostic test is crucial because it can help point a mechanic to the part of your car that needs the most care when the Check Engine light turns on or is acting up. 

Without diagnostic testing, a technician would have to spend a lot of time figuring out any issues, and you would have to pay for the labour, which is rather expensive! 

The only reliable way to identify the problem is through a diagnostic test, even though most automotive centres and automotive parts distributor stores offer a free scan of your onboard diagnostics to help identify the area responsible for the code.

How Do I Know If My Check Engine Light Is Displaying Accurately?

The following are some of the most common reasons that your check engine light has been turned on: 

  • Loose or faulty gas cap 

Your gas tank system’s pipes and valves circulate and prevent the escape of gasoline fumes. This small element alone will easily turn on the check engine light if the gas cap is unsecured. A broken or missing gas cap might result in fuel loss from evaporation or improper fuel system circulation, which is one of the more manageable CEL-related problems.

  • Worn spark plugs

Your engine’s cylinders are powered by combustion, produced when your spark plugs ignite a mixture of fuel and air. If they aren’t firing properly, your engine may misfire, producing higher hydrocarbon emissions and less efficiency.

  • Faulty catalytic converter

To help safeguard the environment, the catalytic converter changes carbon monoxide into carbon dioxide. A malfunctioning one could prevent you from passing emissions testing because it will decrease performance and fuel efficiency, and raise emissions.

  • Dirty mass airflow sensor

To determine how much fuel is needed to run the engine, the amount of air entering the engine must be measured. That’s the job of the mass airflow sensor (MAS). The MAS is susceptible to oil and dirt buildup, so cleaning it might do the trick.

Benefits of a full car diagnostic test

Before the invention of automobile diagnostic testing, locating issues was time-consuming and expensive, especially considering that owners of cars only brought them to mechanics after a breakdown or other serious defect. 

Nowadays, computerized auto parts can spot issues long before they result in a breakdown. To provide specialists with a complete picture and the best possible repair, diagnostic equipment can also analyze a car’s computer system for manufacturer notifications and stored information about the car’s history.

Another great experience at Sil’s. The experienced team provided a detailed estimate including photos, a loaner car and necessary, quality work. They changed my tires, replaced brakes, treated or replaced several fluids and got my car ready for spring travel. Thanks Sil’s for keeping my car safe and reliable!
