To be frank, diagnostic tests make our jobs easier and your auto repair bill less expensive. Your European automobile is designed to receive a diagnostic test if something goes wrong. This test points us to the direct problem without any guesswork. This makes repair in your European automobile much quicker than it would if we had to diagnose the problem without the benefit of diagnostics.
Main Computer Chip
Your European automobile has a main computer chip that is called the engine control module. Some people also call this chip the engine control unit. Either way, this chip is designed to handle many of your vehicle’s operations, such as firing the spark plugs in the correct order in the combustion chamber. This chip is crucial to your European automobile. In fact, if the chip were to malfunction, your European automobile will stop running immediately and you will not be able to get it started again.
System Sensors
Your European automobile is also equipped with several sensors in the systems that communicate with the engine control module. These sensors are designed to keep a continual eye on their systems to make sure everything is operating as it should be. If something goes wrong, the sensors determine what that problem is and send an error code to the engine control module. The module will try to repair the problem on its own. If it can’t, it will turn on a dashboard warning light.
Communication
This communication is crucial. In fact, if you look at the dashboard when you first start your European automobile, you will notice that all of the warning lights turn on. Each system sensor is conducting a test to make sure the system is functioning properly. Once the engine control module gets the okay from a system sensor, it turns off the dashboard light. In addition to communicating when you first start your European automobile, the sensors and engine control module communicate while it is running, as well.
Diagnostic Test
Naturally, because the engine control module is the main computer chip, it stores a ton of information about how your European automobile is operating. If you end up with the dashboard warning light such as the check engine light, we can run a diagnostic test that will download the error codes that the engine control module received from the system sensors. This tells us the exact problem.
As you can see, diagnostic tests are beneficial because they allow us to find problems reported to your European automobile’s main computer chip. If your European vehicle is acting strangely or you have an illuminated check engine light, bring the automobile to our shop for a diagnostic test.
