So, your "Check Engine" light is on. What now?

We all love our cars & trucks, at least most of the time and here at Tuner Tools it's our job to help out when something like that pesky "Check Engine" light diminishes the feeling of a finely tuned and well running ride. You know there's something wrong, or at least there might be, but what is it? Is it something serious or did I forget to put the gas cap back on right?

In this edition of the Tuner Tools Summer Cruisin' Series, we'll focus on the On Board Diagnostic or OBD-II side of your car as well as some of the easy to use and inexpensive tools available to help you learn what's going on with your car and why that light is on. We'll also touch on some of the more advanced uses of the information from the OBD system that can be incredibly useful when you're trying to get a performance equipped vehicle to run like you know it could.

Please read on.......

So What Is This "OBD-II" Anyway?

ImageOn-Board Diagnostics, or OBD, in an automotive context, is a generic term referring to a vehicle's self-diagnostic and reporting capability. OBD systems give the vehicle owner or a repair technician access to state of health information for various vehicle sub-systems. The amount of diagnostic information available via OBD has varied widely since the introduction in the early 1980's of on-board vehicle computers, which made OBD possible

OBD-II is an improvement over what came before in both capability and standardization. The OBD-II standard specifies the type of diagnostic connector and its pinout, the electrical signalling protocols available, and the messaging format. It also provides a candidate list of vehicle parameters to monitor along with how to encode the data for each.

Finally, the OBD-II standard provides an extensible list of DTCs (trouble codes). As a result of this standardization, a single device can query the on-board computer(s) in any vehicle.*

More detail and the history of OBD is available on our partner website All OBD.com should you wish to learn more.

* All cars & light duty trucks built for sale in the United States since model year 1996 are required by law to be OBD-II compliant. In EU member countries, this requirement was made law begining in model year 2001 for gasoline powered passenger vehicles and 2004 model year for diesel power passenger vehicles
