    1.1 Introduction Congratulations! You've purchased an automotive scanner that can unlock the fault code information stored in the on-board computer(s) of your car or light truck. This information gives you the power to identify and repair problems that may arise with the operation of your vehicle's engine. Cars and trucks cannot completely diagnose their problems, and no scanner available can tell you with pinpoint accuracy what is wrong with the vehicle.

    OBD II In 1994, manufacturers began equipping vehicles with a new class of computer technology which puts more processing power in the vehicle than ever before. It is called On-Board Diagnostics, Second Generation (OBD II) and offers increased system monitoring and diagnostic information. Beginning January 1, 1996, vehicles sold in the U.S.
  • Page 35 What does the computer control The main control areas of the vehicle computer are fuel delivery, idle speed, spark advance, and emission controls. Some on-board computers may also control the transmission, brakes, and suspension systems as well. What has not changed A computer-controlled engine is very similar to the older, non-computerized engine.
  • Page 36 it uses fuel injectors (either in a throttle body or at each intake port). Fuel injectors are far more precise than carburetor jets, and create a much finer fuel “mist” for better combustion and increased efficiency. In addition, most fuel injection systems have ways of measuring exactly how much air is entering the engine, and can calculate the proper air/fuel ratio using lookup tables.
  • Page 37 About Diagnostic Trouble Codes (DTCs) Engine computers can find problems The computer systems in today’s vehicles do more than control engine operations—they can help you find problems, too! Special testing abilities are permanently programmed into the computer by engineers. These tests check the components connected to the computer which are used for (typically): fuel delivery, idle speed control, spark timing, emission systems, and transmission shifting.
  • Page 38 About the Malfunction Indicator Lamp (MIL) All OBD II compliant vehicles have a “Malfunction Indicator Lamp” or MIL. In the past, the MIL has been referred to as a “Check Engine” or “Service Engine Soon” light. Normal operation The engine computer turns the MIL ON and OFF as needed. This dashboard message is either amber or red, and maybe labeled with “Check Engine”, “Service Engine Soon”, “Service Engine Now”, or marked with a small engine picture or diagram...
