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.
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.
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.
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.
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.

Called to book my vehicle in for a quote because my exhaust broke right behind one of the flex pipes. They were able to give me a quote super quick and had both flex pipes replaced in an hour. I had it quoted at a different place right before this and the other place quoted it over 4 X more expensive AND they couldn't do it until the next day. If the first quote seems too expensive, always get a second quote. Highly recommend True Auto Care and I'll definitely be back! Thanks!

A very friendly and welcoming place. Got me booked in and service completed quickly, but didn’t skip over the little details that show care and attention to detail, in the name of speed. They even took the time to put my spare tire and all the tools I used to change my tire back together properly and away the way it was supposed to be in my jeep (I had just thrown them in the trunk). They left my car clean, were respectful of my time and even a little bag of cookies with a thank you note. Top notch from start to finish. Will definitely be returning to them for future service needs.

Ken Carter Dec 12, 2024
Stellar service ... again!! Limped into the shop at 2:30pm... with a "flat" run flat. After a quick assessment, they saw that my tire was slashed by something on the road. (I remember hitting something before my pressure sensors went crazy!). Immediate shuttle into town so I wouldn't be late for my appointment! Unfortunately, my run flats weren't something they stock. Update after my appointment.... "We can get you back on the road tomorrow". 10:30 next morning... text "your car's done!" Quick call gets me another immediate shuttle! Great to have them juggle their schedule to fit me in... great service, great price.
