A Brief History Of OBD

On-board diagnostics (OBD) is a system that relies on sensors and computers in your car to display vital information about how your car is operating. In its earliest days, OBD took the form of cooling system gauges, tachometers, oil pressure gauges, and fuel level indicators to give us basic information about a car's condition. Nowadays, OBD systems can tell you about everything from crankshaft and camshaft position to manifold pressure to ignition misfires.

Computerized OBD systems started coming online with Volkswagen's fuel injected models as early as 1969. These early versions were very basic and would illuminate a malfunction indicator if there was a problem, but they didn't provide any useful diagnostic information about the actual nature of the problem. Later on in the early 1980s, General Motors began to implement a computerized assembly line diagnostic link (ALDL), which was actually capable of reading out error codes. New OBD2 systems and scanners use a digital communication port that relies upon a series diagnostic trouble codes, which identify the problem so it can be found and fixed quickly.

In 1991, the California Air Resources Board (CARB) instituted new regulations that required every new automobile to have an OBD1 system. These initial systems weren't standardized and each car manufacturer used its own connectors and data link protocol. In 1994, the Society of Automotive Engineers (SAE) recommended a standardized connector and data link protocol for all OBD systems and this became what is now known as OBD2. At the same time, CARB required that any car manufactured from 1996 and onward have the standardized OBD2 system installed and the U.S. government followed suit with nationwide regulations. The European Union instituted OBD2 regulations in October of 1998.

How To Use An OBD2 Scanner


Go to top.

Using an OBD2 scanner is actually quite simple and it doesn't require any mechanical knowledge. That's because OBD2 scanners don't fix problems, they identify them so that you, or a mechanic, can fix them without having to waste time trying to figure out what is wrong. OBD2 scanners are simply a diagnostic tool. Think of it like a doctor's visit for your car.

The first step in using an OBD2 scanner is to find your vehicle's diagnostic or data link connector (DLC). It is a somewhat triangular 16-pin connector that looks similar to old computer monitor and printer ports. It is most often located underneath the left-hand side of the dashboard near the steering column. Once found, you insert the OBD2 scanner connector, this can either be a cable attached to the scanner or a separate device that wirelessly sends the information, so it can initiate communications with your onboard computers. You will then see some kind of message like "establishing data link" or "searching for a protocol." If your screen does not light up with some kind of message, your device has not made a connection and you should try jiggling the connector or unplugging it and plugging it back in.

Next, you will have to enter your vehicle's information, which may include the make and model, VIN number, and engine type. Each scanner will require different information depending on the device model and manufacturer. After you scanner has made a connection, you've entered your vehicle information, and it has booted up, you can then start searching for trouble codes. Browse through the scanner's menu until you see something that says "trouble codes", or just "codes". You may or may not be presented with an option to choose from specific systems like the transmission, brakes, powertrain, etc. If you are, select the system you want to check and then you will be presented with a code. If you aren't presented with an option of systems to check, your scanner will just immediately present you with the trouble code.

Understanding OBD2 Codes


Go to top.

Using the OBD2 scanner is just the first step. Next, you need to learn how to read the code you are presented with. You will be shown either an active code or a pending code. An active code alerts you to a malfunction that is keeping your check engine light illuminated. A pending code means that the OBD2 scan has failed an emission control system operation once, and if it fails again, your check engine light will be illuminated. At this point the malfunction will become an active code.

All of the trouble codes displayed will start with one of four letters. "P" is for powertrain codes and covers the emissions system, ignition system, fuel system, transmission, and engine. "B" is for body and covers power seating, seat belts, airbags, and more. "C" is chassis related and will cover your axles, brakes, wheel pressure, suspension, etc. "U" is for network and other communication-related issues.

The second digit lets you know if it is an OBD2 standardized generic code or if it is manufacturer specific. 0 means it is generic, and 1 means it is manufacturer specific. The rest of the digits will identify the exact problem your car is experiencing. Since there are literally thousands of fault codes, nobody will have them all memorized and your next step will be to consult a list of OBD2 codes to find out what is wrong with your car.


#10.Blusmart CAN/OBDII/EOBDII Diagnostic Scan Tool Memo Scanner Live Data Code Reader


Excellent product for the price. I have used this machine on several different cars and it has yet to disappoint me. On Dodge, i has been able to tell me what oxygen sensors are bad. most tools just say oxygen sensor and not which ones. This one, tells which one and what side and whether it is before or after the catalytic converters. that is a very big deal when your dealing with 4 of them and they cost upwards of 95.00 each. I have been able to reset cars computers and read codes easily and also drive while it reads what's going on in the engine and the PCM. This can be a very helpful tool. Read the directions.

#4.MAOZUA V2015 D900 CAN OBD2 Scan Tool Live Data Diagnostic Engine Code Reader


Anyone that does mods to their vehicle is likely used to seeing some kind of CEL at some point. I have an Android app and Bluetooth adapter which works well almost all the time. Almost is the key word as there are times with my car and other cars like it that it doesn't work perfectly every time. This is faster and easier than using the app/adapter too which is nice. (IF it worked with the modded car that'd be even better...more on that later and in the video).

The onscreen display is pretty easy to use and see. It's nice to include the carrying case as well.
