The OBD concept, your cars human side
The design of the OBD scan tool is meant to read your engine’s mind. Seems hilarious is it? Sadly that is how it is. With the scan tool, reading the mind of your car engine has never been this easy. In a break from the past where the car repair process involved lots of labor, it has been quite an easy task with these engine mind reading tools.
The amusement caused by the simplicity of the engine condition diagnosis achieved by the OBD scan tool is what may take you back. With its prolific features, you are assured of retrieving any useful information from your engine’s mind.
Moreover, the new brands in the form of OBD 2 are quite wonderful. They can definitely get you the engine mind status every minute, thereby saving you lots of time which would be wasted trying to get the information using the manual methods.
What is the diagnostic engine mind reader made of?
These engine mind reads in most cases comprise several manly connected parts. Some of them include;
- The sensors– these are in most cases two fold. The carbon dioxide sensors and the oxygen sensors. They are the most important aspects of any given scan tool software. The sensors form the base because it is at this point that all the scanning takers place. With the carbon dioxide sensors, the rate of emission will be well monitored while the temperature and the metabolism are taken care of by the oxygen sensors.
- The diagnostic metering– this is another component which assist this engine mind reader in achieving its major aim. The metering provides the data reading as it comes. It is this area which is also tasked with checking the vehicle fuel status and the general exhaust condition.
- The light– The presence of the malfunction indicator lamp is even a plus to most of these OBD scan tool because it is what is usually set to flicker should there be any car engine fault. The MIL sends signals in the form of light warning the user of the fault.
- Engine misfire detection– it is one of the latest additions to the OBD fault detection systems. The level of the engine function is better checked using this system.
- Canister purge system monitoring-which is in most contemporary car systems is known as the evaporative emission control mean t to check the level of fuel flow.
- Catalyst efficiency monitoring– these are oxygen targeted sensors which check the level off hydro carbon efficiency.
One thing is clear; all these sensory systems meant to check your vehicle’s engines mind are all targeting the common denominator known as the code. The code readers are therefore strategically placed to enable the driver have unlimited access to the viewership of the data it is streaming in live as the scans usually do.
The ideal place for placing the scan tool is in most cases within the area of the drivers with the display well within the view of the vehicle user.
The OBD tool is made to connect to the car engine through the OBD connector. This is usually a 16 pin connection point with the pins color coded for different purposes. Because of the standardization requirements by EPA, the connector can fit any coding use, which is an important part in knowing the state of mind of your car.
In spite of the number, the 16 OBD scan tool pins are not all usable. However, the scan cannot function without certain specific ones.
Most codes read by the reader are in the form of the manufacturer specific and generic codes. The generic code is the most commonly read data code among a cross section of the OBD scan tools. The coverage of the generic codes therefore spans across most vehicle brands.
The other type of code known as the manufacture specific is unique to every vehicle brand. In most cases, there is some scan tool designed to read only such codes. However, most universal scan tools will be able to cut across the diverse coding making it a non issue.
Knowing the car brand and the scan tool to be used therefore will make the process of reading your car mind very easy, you can opt for the new model wireless scan tools and you’ll love driving your car.
