OBD 2 Pinout Explained

On-Board Diagnostics II, or OBD2, is a self-diagnostic and reporting system in modern vehicles. It consists of an Electronic Control Unit, several sensors, and indicator lights. The sensors inspect the various subsystems within the vehicle and report any faults and abnormalities to the ECU.

Of course, simply reporting faults would be pointless if there was no way to read the errors and act on them. Hence, the ECU generates Diagnostic Trouble Codes and stores them for inspection by external OBD scanners. These codes are accessed through an OBD2 connector plugged into the 16-pin OBD port.

Consequently, repair technicians can analyze the error codes using a scan tool attached to the other end of the connector.

Are you confused by the various terminology thrown about? Read on to learn what an OBD2 connector is and its purpose in your vehicle.

What is the OBD2 Connector for?

The OBD2 connector is one end of the adapter cable plugged into your vehicle’s OBD port. It is a communication interface that allows you to transmit information between a diagnostic scan tool and the vehicle’s OBD2 system.

OBD2 connectors come in two flavors; wired and wireless. As the name suggests, the wired connector must be physically attached to the scan tool through the cable. On the other hand, wireless OBD2 connectors interface with the scan tool using Bluetooth or WiFi.

The OBD2 connector is designed to read and translate real-time diagnostic information from the Electronic Control Unit (ECU). As such, you can tell what is wrong with the vehicles from the error codes received through the connector. Furthermore, it allows you to use scan tools to reprogram and repair the various subsystems within the vehicle. Recently, remote diagnostic systems have become increasingly popular.

OBD2 Port Pinout Types

There are two major types of OBD2 connectors. Type A connectors have a 12V output voltage and are commonly found in small vehicles such as cars. However, type B connectors are usually found in medium-sized and heavy vehicles. Moreover, they have an output power supply of 24V.

Baud rate is the rate of information transfer in serial communication channels. A rate of 24,000 bauds means the port can transfer up to 24,000 bits per second. Type A connectors have an approximate baud rate of 500,000 bauds, while type B connectors have a maximum baud rate of 250,000.

The higher the baud rate, the shorter the length of the adapter cable. As such, it is not uncommon to find type B connectors with longer cables than type A connectors. Nevertheless, you should note that this is not a reliable method of distinguishing between the two cable types.

OBD2 Pinout Explanation

OBD2 connectors are typically 16-pin ports, each pin serving a distinct purpose. Some pins use standard protocols defined by the Society of Automotive Engineers and the International Organization for Standardization. Other pins are left to the manufacturer’s discretion.

The table below gives a quick overview of each pin in a generic OBD2 connector.

16 Vehicle Battery Power Connects to the vehicle’s battery to power scan tools. Type "A" 12V/4A; Type "B" 24V/2A

Each of these pins is explained in-depth below.

SAE J1850 PWM (Pulse Width Modulation)

  • Bus positive pin (2) and bus negative pin (10) of the protocol.
  • It uses variable pulse width modulation at 41.6 kb/s.
  • It is common in Ford vehicles.
  • Pulse Width Modulation changes the analog signal to digital in a square wave.

Controller Area Network (CAN)

  • It is a network of independent controllers.
  • It is headless; no host computer.
  • It uses a bus communication protocol.

SAE J1850 VPW

  • Commonly used in General Motors vehicles\
  • It operates variable pulse width at 10.4 kb/s.
  • Pins 2, 4, 5, and 16 have SAE J1850 VPW.
  • General Motors developed the Variable Pulse Width encoding method.
  • VPW is better than the PWM scheme.

ISO 9141-2

  • It is an old protocol
  • Mostly used in European vehicles, some Asian vehicles, and Chrysler.
  • It uses asynchronous serial communication at 0.4 kb/s.
  • It is optional on pins 7 and 15 (pins 4, 5, and 16 are must-haves).
  • This protocol represents voltage logic in 0 or 1 form. Logic 0 represents low voltage and Logic 1 represents high voltage. Each bit of information is 96 us long.

ISO 14230 KWP2000

  • It operates at 10.4 kb/s and is used for serial asynchronous communication.
  • This protocol is most common in Europe and Chrysler vehicles.
  • This protocol is used in Asian vehicles having pin 7 K-line.
  • It is optional in pin 15.
  • KWP is Keyword Protocol. It is a communication protocol that is applied to the OBD system.

ISO 15765-4 CAN (SAE J2480)

  • ISO 15765-4 CAN is available in vehicles built in 2008 or later in the US.
  • Pins 4, 5, 6, 14, and 16 support this protocol.
  • OBD2 protocol consists of 4 variants.
  • It works on a 2-wire communication method.
  • It can handle up to 1 Mbps.

Main Car Manufacturers OBD2 Connector Pinouts

OBD2 ports are standardized to work with any commercially available scan tool. However, several pins, including 1, 3, 8, and 9 are not required for standard communication. As a result, vehicle manufacturers encode these pins to transmit information specific to each vehicle's make and model.

Furthermore, the standardized pins encode different types of data to be decrypted by the scan tool. Finding specific information about each vehicle manufacturer can be difficult and confusing. Luckily, we have compiled a spreadsheet of the OBD2 pinouts of some popular car manufacturers. Simply click on the name of the brand you're interested in to see its OBD2 pin layout.
