Vehicles, these days, are equipped with sophisticated electronics that allow drivers to keep track of their vehicle’s performance on board. However, this onboard diagnostic system is only capable of showing a limited amount of information through dashboard signals. If your vehicle is continuously showing an issue through little lights placed on your dashboard, you should immediately consult a mechanic.
The mechanic is going to scan the flaw with the help of an OBD reader or scanner that gets connected with the help of an OBD port. In simple terms, it is a car diagnostic connector that allows the OBD scanner to connect with the OBD system of a car and helps the mechanic take an in-depth review of the entire vehicle. The continuous illumination of the check engine light may signal some other problems like ignition, emission, or transmission.
A car diagnostic connector, which connects with the OBD port, allows mechanics to get in-depth details about the flaws or issues in the vehicle recorded by the ECU (Engine Control Unit). We have put together some details about this OBD connector to help you understand the concept properly. Further details are given below:
As the OBD port works as the interface between an OBD reader and the OBD system of the car, it provides a place to plug the scanner and establish a connection with the ECU. This port is usually located under the steering or instrument panel on the driver's side. The car diagnostic connector that comes with the scanner connects with the OBD port.
The pinout of an OBD connector for cars consists of 16 pins. Some of these pins are simply blank and play no part in the communication between ECU and the scanner. Pin 16 is used for the power supply, in the case of cars, it is 12V. Pin 4 and 5 are used for grounding purposes. Pins 7 and 8 are used for asynchronous and synchronous communication protocols. On the other hand, pins with 6 and 14 codes are used for data transmission.
While the car diagnostic connector generally comes with a cable, there are some Bluetooth connectors as well to transmit data to computer systems directly from the vehicle.
As we all know the OBD system has its own language, the car diagnostic connector that is used to connect the scanner with the OBD system using a port fetches data. This connector then transmits it to the scanner, which shows the information and measurements received and perceived by various electric modules placed in the vehicle. The scanner shows the perceived information in the form of codes that can be difficult to understand for beginners but if you learn the basics right, you can easily understand these codes. These codes are generally displayed in 5 figures. The first figure is a letter, while the rest of the units are in the form of digits representing manufacturer, trouble, and further issue respectively.
