Your car runs well, there are no strange sounds or issues, and it gets you from Point A to Point B. That means everything is fine and dandy, right? Not necessarily. There could be a small problem lurking somewhere within your vehicle’s engine or systems that’s not immediately obvious. But as you keep packing on miles, this insidious problem will keep getting worse. When you finally notice it, your car may no longer be in safe, drivable condition. But the good news is that you can catch problems early with a car diagnostic test. This test analyzes the vehicle’s engine through the engine control unit (ECU) — its central computer. Read on to learn how often you should get a diagnostic test and what the test entails. How Often Should I Get My Car Diagnosed?First things first, how often does your car need a diagnostic test? Well, this first question is also the most difficult to answer. Strictly speaking, your car doesn’t need a diagnostic test. Unlike brake repairs or oil changes, the test doesn’t actually maintain any single-safety or operating-critical component. It simply probes your car’s systems for any possible stealthy issues. That said, it’s still a good idea to get a car diagnostic test at least annually. If you really want to stay on the safe side, a quarterly computer system check isn’t too much. This way you’ll ensure that every system and part in your car is functioning as usual. You’ll also save money by not having to resort to emergency repairs and roadside assistance. Situations Where You Need a Diagnostic TestApart from the annual tests, there are certain times outside the regular schedule when a diagnostic service is in order. If you encounter any of the below situations, bring your car in for a check.
What Exactly is a Diagnostic Test on a Car?If your car was built in the last three decades or so, it will be heavily computerized. You might not think so, but there’s an entire network of chips and sensors in your vehicle that constantly track the performance of its engine. Although computers can always glitch, this degree of computerization is a huge benefit to technicians. During a diagnostic test, they tap into the car’s computer systems to identify any problems the ECU hasn’t caught. That said, your car’s computer won’t clearly tell the technician, “My transmission is failing.” Instead, the technician will interpret a number of performance reports to identify the most likely problem. Because diagnostic tests require expert knowledge and specialized equipment, it’s best to bring your car to a professional auto service shop for testing. Which Parts Will Technicians Test?Car computer systems have advanced greatly in a relatively short time. As a result, technicians can now identify problems with many different components and systems through a car’s computer. During a diagnostic test, they will check for:
The diagnostic test gives technicians a solid idea of the overall health and condition of your car. But it can’t check for every possible issue. For example, depending on the age and make of your car, it may not be able to identify things like worn brake pads or whether you need wheel alignment. What Happens During a Diagnostic Test?In short, technicians connect to your car’s computer system to identify hidden problems when they run a diagnostic test. Naturally, the full process is more involved than that. Although different car service shops have different working methods, the basic workflow looks like this:
How Long Does a Car Diagnostic Test Take?On average, a car diagnostic test takes about an hour to an hour and a half. But this is just a rough guess because it’s very difficult to accurately estimate how long an engine diagnostic test takes. Getting the error codes from your car’s computer usually only takes a few minutes, but that’s just the beginning. The codes won’t tell technicians exactly where the problem is, so they’ll have to check the most likely areas using their own two eyes. Depending on the issues they discover and the extent of repairs they need, the length of the diagnostic test could stretch to several hours or even days. Here are some things that could cause the test to last longer than about an hour:
How Much Does the Test Cost?As is usually the case with car maintenance services, it’s very difficult to say how much you’ll have to pay for the diagnostic. The national average price for diagnostics is about $100, fluctuating up or down by $50. Of course, that will only cover the price of the diagnostic service itself. If your car needs any repairs, those can add to the final cost. Fortunately, you may be able to get a diagnostic test done completely free. Customer-oriented auto repair shops, like Advanced Automotive, can give you a free courtesy check when you bring your car in. The technicians will inform you about any issues they find and leave the choice of whether to address them to you. 5 Benefits of Getting Your Car DiagnosedThe computerization of cars has made life easier for both car owners and technicians. Running a quick diagnostic test with a handheld scanner brings great benefits to everyone involved, including:
