Car code readers can only be used on OBD II (on-board diagnostic two) systems integrated in all vehicles since 1996. Some GM models began OBD II in 1995. OBD II standardized the location and plug application of the vehicle's computerized system, which simplified the equipment needed and the diagnosis time. The first obdii code scanner was expensive and more complicated to use because they required different data chips for various car models. The Auto Code Scanner today require no data chips and are much more affordable to the home mechanic. Such as MaxiScan EU702 Code Reader and maxiscan FR704 Code reader from Xcardiag online shop, these multifunctional OBD2 Code Scanner Readers are great.

Instruction:
1. Open the driver's-side door and look under the dash for the trapezoidal diagnostic link connector (DLC). Since the implementation of OBD II, it is mandated that all DLCs be located within two feet of the steering wheel. Most are located under the driver's-side dash on either side of the steering wheel column. However, this is not the case for some models. Refer to the owner's manual of the vehicle if necessary to locate the DLC.
2. Remove the DLC cover if there is one. Some vehicles don't employ DLC covers. The covers simply pull off.
3. Insert the plug of the maxiscan EU702 (EU702 for example) into the DLC outlet. This outlet is easily identified, since it is similar in shape to the code reader's plug. The vehicle's battery will provide power to the code reader.
4. Turn the ignition key to the "on" position without starting the engine. This will provide power to all electrical components and illuminate the instrument panel lights.
5. Read the menu of the obdii code scanner and use the key or arrow to move to the "read codes" or "DTCs" (diagnostic trouble codes) option. Since Auto Code Scanner, made by many manufacturers and feature slightly different options, you will need to read the manual of the code reader to fully understand all of its functions.
6. Press the "enter" key, if applicable, once the "read codes" or "DTCs" option has been selected. Refer to the code reader manual to determine which DTC triggered the malfunction indicator lamp (MI, also known as the check engine light or service engine light).More related articles are here.
7. Clear the code, if applicable and desired (some inexpensive models simply read codes), by scrolling to the "erase code" selection and pressing enter. Some fault code readers may feature an "erase" button which simply needs to be pressed.
8. Wait until the "command set" message appears on the onscreen menu of the OBD2 code scanner.
