This Site Was Built With You In Mind!
by Eddie Carrara
Then in 1996, OBD2 was introduced to all new vehicles built in the US, and was mandated by the government. The OBD2 system was implemented to all new vehicles; it is designed to lower vehicles emissions and make them less intrusive to the environment.
What is unique about OBD2 is that it is a universal application for all late model vehicles and can be accessed through a universal port called the DLC (Data Link Connector) or OBD2 port (On Board Diagnostics 2 Port) which is usually found under the dash, on the driver's side on most vehicles. Some vehicles, like Honda, have place them behind the ashtray, but for most vehicles, looking up under the dash where the drivers legs would be positioned, is where you will usually find this connector.
In earlier years, you would have to bring your vehicle to a
mechanic or own a OBD scan tool, in order to have the auto computer codes or
DTC's pulled from the vehicles ECU (Engine Control Unit). Now it's as easy as pulling out your
Smartphone, iphone, laptop, or tablet and connecting it wirelessly to retrieve
the DTC's, yes you would have to buy an App and a Bluetooth adapter but the
cost is minimal compared to what it would cost to have a garage or shop pull
the code. Shops usually charge a minimum of 1 hour to pull a code, and that
does not include repairing the vehicle.
The benefit to having this Bluetooth adapter is that if you have a simple code, like a gas cap code or a misfire code, you can diagnose it where ever you are, clear it, and be on your way. The second benefit, is knowing what the code is, even if you're going to have a garage or shop repairing it for you, you'll have the knowledge of what's wrong with you car before they even look at it, that information is priceless and you can't get taken for a ride!
The average cost of an ELM 327 Bluetooth OBD2 scan tool is $15- $60 depending on you specific application. If you own an iphone, I recommend buying the iOBD2 for $60 and spending the $4.99 on the App, you're guaranteed not to have any problems with communication or App conflicts. If you're using a Droid, Samsung, or HTC, it will cost less for the adapter and the Free App will give you all the information you need, there are paid Apps, but unless you want to get techie, there is no need to spend the money.
Before you rush out and buy your auto computer codes reader, I highly recommend researching which scanner is right for your phone. The vehicles diagnostic trouble codes are universal, but the phone adapters are not. I recommend reading customer reviews on the product before making a decision, and I recommend purchasing it from an online retailer with an easy return policy, just in case you have any problems, you don't want to have any hassles if you need to return it.
