What is OBD 2 port? The location of the gate on the car? Utilities from the OBD 2 . port

Although the OBD 2 system has been around for a long time to connect car accessories, it may still be far away for many drivers. So what is the OBD 2 port, where is it installed, and what does it do? The following article will help you answer the question.

What is OBD 2 port?

Define

OBD 2 (On-board Diagnostics) is a system that has the function of reading vehicle parameters, monitoring the operation of important engine components, and diagnosing errors of these parts and emitting warning signals. newspaper.

This system has been integrated on cars since 1996 in the US, then developed and put into use in many other regions. More specifically, the models that are integrated with OBD 2 include:

• Vehicles manufactured in Europe from 2004 onwards.
• Vehicles manufactured in Asia from 2009 onwards.

Structure

OBD 2 is composed of one or more central control units ECU (Electronic Control Unit), responsible for receiving signals from sensors on the engine. They are combined with other components on the vehicle such as: MIL diagnostic lights, DLC diagnostic ports and leads. In there:

• The MIL (Malfunction Indicator Light) is the part that sends out a signal to the vehicle owner that the system is experiencing a problem that needs repair.
• DLC (Diagnostic Link Connector) port is a connection part between the OBD system and the central control ECU to receive signals.

When the vehicle is moving, the ECU will automatically set up the diagnostic system and install it into the fault code memory. If the car encounters a problem, the “Check Engine” light or the MIL light on the taplo will immediately light up for the driver to recognize quickly and promptly.

Location of OBD 2 port on the car

Most OBD 2 ports on vehicles are usually located below the brake pedal as a 16-pin connector. In some models, the OBD port can be installed in another location. You should then contact the manufacturer for their exact location.

The benefits that OBD 2 port brings

Report errors and warnings when the system has problems

The key role of the OBD 2 port is to diagnose and warn when a system problem occurs. This will help car owners detect small problems early before they become serious, affecting the vehicle’s operation.

Usually, the traffic accidents encountered can be due to subjective causes , but there are also cases due to objective causes from the vehicle system . At that time, the timely detection and correction of these errors will make traffic safer.

Store vehicle error code information, support technicians to fix errors faster

Thanks to the OBD 2 system, technicians no longer need to manually find faults. Instead, they just need to read the alarm parameters on the system or count the number of blinks of the warning lights, making error correction faster and more efficient.

Install more car accessories such as HUD screen, car navigation

Besides the benefits mentioned above, OBD 2 can also support users to install more HUD screens, car navigation. In particular, the HUD screen helps to display the vehicle status on the steering wheel, including information such as the vehicle’s current speed, distance traveled, positioning, … in line with the driver’s eye view.

The HUD monitor needs to be connected to the vehicle’s system via the OBD 2 port to receive the necessary parameters. Therefore, this gate also works to support car owners to install other accessories with many utilities, making moving more convenient.

The car locator when installed and connected via the OBD 2 port will be used as a mini black box for your car, helping to track and monitor the location and moving schedule of the vehicle. , at the same time giving safety warnings, storing reports of travel schedules efficiently.

Protect the environment, control vehicle emissions

A great effect that the OBD 2 port brings is controlling the vehicle’s emissions . This is also the first purpose to promote the introduction of the OBD 2 system.

At that time, the strict control of the exhaust system from vehicles circulating in the US was a premise for automakers to set up a vehicle emissions monitoring and control system. After that, this system was gradually improved and developed, not only to protect the environment but also to meet many of today’s needs.

Hopefully with the above article, you have gained more useful information about the OBD 2 system in your car, as well as understand more about the benefits that this system brings.
