From model year 1996, vehicles manufactured for the North American market are equipped with a Government required diagnostic system known as On-Board Diagnostics II (OBD II). This system monitors operation and function of all engine management system activity and automatic transmission operation to insure compliance with specified emission levels.
Vehicle emission levels are constantly monitored by the OBD II system and malfunctions are recognized and recorded. A Malfunction Indicator Light (MIL) in the instrument cluster alerts the driver to the fault and the need to have the system checked for fault codes. These codes follow a standard format and are known as Diagnostic Trouble Codes (DTCs).

Presuming you are familiar with the principles of a modern EFI engine, (if not please review the Introduction, in the Scan Tool manual called “Fundamentals of OBD II EFI Engines”:) it may be surprising to learn that it is possible that these engines can be electronically “tuned.” Just as in the “good old days” when (for example) adding a modified camshaft required new jets for the carburettor, and changing the springs and weights on the distributor advance, this ability still exists, and is necessary, when making changes to an EFI engine.

What you should do if the Service Engine Soon light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction. Temporary malfunctions may cause your Service Engine Soon light to illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run poorly.)
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely tightened.

When an explosion occurs in an airbag or the SRS light is turned on, normally both airbag and the controller should be replaced. But this tool can restore the software under the conditions that there is no damage to the controller’s hardware and replace the airbag only, and the controller can be used again.

As an avid car fan, I love working on my cars; but before ScanTool, I was limited by my vehicle’s computer which “hid” the information I needed to understand the problem. Sure computers make cars more efficient and lighter; but, they also hide all the information away in proprietary interfaces.
AutoEnginuity’s ScanTool gives you access to the abundance of data that any 1996 and newer vehicle provides through the OBD-II and optional manufacturer interfaces. It will help you determine what repairs are necessary, and determine whether you can repair it yourself, or whether it’s something that requires more assistance. What’s more, AutoEnginuity’s ScanTool allows you to verify that work you have done—was done properly. Whether you’re an independent service shop, or simply a vehicle owner, now you can diagnose a broad range of vehicles, accurately and quickly, with just one tool.
