WHAT IS A CAR DIAGNOSTIC TEST?
A automotive diagnostic test is a digital analysis of a car’s different internal parts and computer systems. This test is performed using professional car diagnostic tools and software by an automotive technician. They collect data created in the vehicle’s computer system, analyse and then fix problems (if any) detected during the test in the engine, throttle, oil tank, transmission and others.
A full car diagnostic test requires professional expertise and knowledge as well as special tools. However, to some extent you can DIY, if you know how to use an automotive diagnostic tool.
Read on to gain some basic knowledge of car engine diagnostic tests and its importance.

HOW OFTEN A CAR DIAGNOSTIC TEST SHOULD BE PERFORMED?
The need for a car diagnostic test usually arises when the vehicle’s dashboard illuminates a warning light, i.e. “check engine light”. By learning how to do a simple diagnostic test by yourself, you can do it as frequently as you want to prevent minor problems compounding into bigger chaos. This enables car owners to save the cost of repairs by fixing small issues instead of waiting for the vehicle to break down. However, either you buy a used car in the UAE or new one, make sure that a diagnostic test is performed on a regular basis to ensure its performance.
WHAT PARTS OF CAR ARE TESTED IN CAR DIAGNOSTIC TESTS?
Although they analyse various aspects of the vehicle, they specifically check issues with:
- Car’s engine and individual components
- Car’s transmission and responsiveness
- Brake responsiveness
- Contamination or faults with car’s exhaust system
- Wear and tear or breakage with major components including, but not limited to, fuel injector, ignition coils, throttle.
HOW LONG DOES A CAR DIAGNOSTIC TEST TAKE?
Full car diagnostic tests are done with a basic scanner (OBD-II) using a diagnostic software that takes only a few minutes. However, doing an automotive diagnostic test is only the initial part of the maintenance process. To reap value from these tests, the key step is carrying out repair based on the information received and taking preventative measures.
We have detailed the procedure of car diagnostic test in a few pointers:
- The scanner examines the “check engine” light code. The car’s computer, alongside the warning light, generates another code (trouble code) that indicates the source of the underlying problem.
- The technician plugs the diagnostic scanner in the car, in order to read the trouble codes. After which they translate the codes on the diagnostic test tool to take necessary measures.
- The technician researches your vehicle to identify where exactly the problem is and what it is. If the check engine light code indicates that the exhaust system is not working, the technician will then first check that.
- Once the issue is identified, the technician performs the repairs that may either include damaged parts replacement or clean the clogged parts caused by dirt and debris.
- Another final car engine diagnostic test may be performed after the repairs to ensure everything is fixed.
If you’ve read it through, you would understand the value and significance of performing car diagnostic tests. These tests are significant and should be performed regularly for timely maintenance of the vehicle. If you buy automotive tools for the test, you can easily do it at home to ensure your vehicle is performing well. An automotive diagnostic test will save your car from getting damaged in the long-run due to malfunctioning of other auto parts.
