Vehicle Diagnostics in Fergus, ON

Vehicle Diagnostics

Annual checkups from your physician keep you in good health, right? The same goes for your car—regular diagnostic tests can detect problems with your vehicle before they require expensive repairs or, worse, leave you stranded on the side of the road after a breakdown.

What is a  Diagnostic Test?

Typically, a car diagnostics test refers to the process where each part of an automobile is deeply examined and thoroughly checked to capture the root cause of any issues inside an automobile. It involves using special software to highlight the causes or faults and issues that are causing problems to your vehicle’s engine or elsewhere. This can be detected due to built-in processors, microchips, and sensors.

This is the first thing we check when a customer enters the True Auto Care shop with an issue is OBD. OBD is an abbreviation for On-Board Diagnostic. It is the standardized system that allows external electronics to communicate with a vehicle’s computer system.

It has become more important as automobiles have become increasingly computerized, and software has become the key to resolving many issues and unlocking performance.

What areas of the car can be tested?

Diagnostic tests can reveal issues with a car’s engine, transmission, exhaust system, brakes, and other major components like fuel injector, air flow and coolant, ignition coils, and throttle performance.

A common misconception about car diagnostic tests is that technicians can use code-reading tools to pinpoint the problem that caused the check engine light to illuminate.

In reality, the code informs technicians about which engine or component parameters are out of range, but it does not explain why. That’s where the technician’s experience and expertise come in handy, as the technician uses their knowledge to diagnose the underlying problem.

How long does a full vehicle diagnostic take?

Most full diagnostic tests can take an hour to 90 minutes to complete. However, occasionally, issues arise that complicate matters or your vehicle may have components that must be removed before a diagnostic test can be performed. Therefore, the time could range between two and three hours.

Main Advantages of Auto Diagnostics

Before the invention of car diagnostic tests, identifying problems was time-consuming and costly, especially since car owners only took their vehicles to mechanics after a breakdown or other severe malfunction.

Mechanical automobile components can now detect problems long before they cause a breakdown. Diagnostic tools can also search a vehicle’s computer system for manufacturer notifications and store information about the vehicle’s history, providing technicians with a complete picture to perform the best repair possible.

Great service and very helpful.

Moe Jacobs Nov 11, 2023

Was driving and got a chip from a rock hitting the windshield. They got me in and out within 15 minutes of walking in. Was super friendly and helpful, taking me on the spot and ensuring that my chip wouldn't spread worse. They spoke me through the options I had also instead of insisting on one type of repair. It's barely even noticeable and the majority of the damage has faded from their work. (note these photos are "up close" shots, from further back you hardly see anything! 98% better then it was!)
