There are a lot of measuring gadgets if you take a look at your car’s dashboard. This whole panel with all the measuring device on it is called the instrument panel. The main function of the instrument panel is to make sure that the drivers will see the light indicators that are indicatory of car problems. The light indicators may blink or may not light at all and the arrows will move to indicate if your car’s oil pressure and fuel are still okay or not so you can have it checked.

The thing that would come into your mind is how do these indicators get the information from different car parts. The answer is that there is the instrument panel working hand-in-hand with the engine computer. Information gathered within different car parts is done by the engine computer and then the reading will be shown on the instrument cluster.

These car computer parts are composed of the ECU, which is responsible for the temperature stabilizer of the coolant, and the transmission controller which holds responsibility for the speed of the vehicle too.

The gathered information from these parts is then distributed and collected in the communications bus. This data being sent by the engine computer contains two parts, which are called the header and data. The header serves as the numeric identification of the data that will be sent. For instance, the temperature data will be dispatched to the communication bus by the car computer. With the header, the communications bus can detect that the information received is about the coolant’s temperature.

The next part is called the data. This is the numeric value that is set for the exact information value. For instance, if it says the temperature is 200 degrees Fahrenheit, then the data that was sent to the communication bus is 200.

Once the information has been received and identified in the communications bus, it will then distribute the information to the right gauges found on the instrument panel. This becomes a reading being displayed to you while driving.

Since the instrument panel is very vital to your car, you have to know if the instrument cluster is working properly. In order to know if it is working properly, you schedule it for regular check, maintenance and calibration. This way you can make sure that you are getting the accurate value that you will need in order to keep you safe on the road.

This is how the car engine computers work hand in hand with the instrument panel to come up with the needed car readings. Henceforth, these essential car parts should be well coordinated with each other so that you will always be informed if the car is working well. Nothing can be better than keeping your car sound for your own safety.
