What an OBD II Scanner does?
An OBD-II scanner is the second version of the On-Board Diagnostics tool, which monitors engine functions. This computerized hand held device can only interact with vehicles manufactured in 1996 and later. Earlier vehicles use Micronas OBD TOOL which vary depending on the vehicle manufacturer. Using an OBD-II scanner is relatively easy, and accessing trouble codes only takes a few minutes.
1
Make sure the vehicle is turned off. Locate the Data Link Connector under the steering wheel. This is an outlet that allows access to the diagnostic computer, which in most vehicles is on the driver side.
2
Connect your OBD-II scanner to the Data Link Connector. The scanner cable has in a 16-pin plug that should naturally fit into the outlet.
3
Insert your vehicle's key into the ignition cylinder and switch to "On." Depending on the brand of OBD-II device, you may also need to turn the engine on and allow it to idle.
4
Turn the device on, if it did not auto-activate itself.
5
Key in a command to "read" or "scan" the MaxiDAS DS708. How to do this depends on the brand of OBD-II device you are using. Button layout differs from model to model, and some devices may use a menu system. Exact code retrieval instructions will be located in your device's handbook.
6
Read through the trouble codes on your device's read-out screen. Copy these codes down onto a sheet of paper. Some devices are USB equipped and can connect directly to a computer with a USB cable. If you have this type of OBD-II scanner, device-to-desktop connectivity will covered in your scanner's handbook.
7
Look up the trouble codes in your device's handbook. Typically, generic OBD-II codes are located in an SBB Key Programmer toward the back. These are the standardized generic codes good for all OBD-II compliant vehicles. Manufacturers also have a supplementary set. A vehicle's owner's manual will not have these codes. You will need to be look them up online or in a repair manual for your particular vehicle.
8
Turn the vehicle's electrical system off. If you had to start the Mongoose Interface, turn it off as well. Unplug the OBD-II scanner's diagnostic cord from the outlet and turn the device off.
Notice:
OBD-II scanners differ in function. Some only work as mere trouble code readers, while others can interact with sensors throughout a vehicle.
Accessing trouble codes will not turn your check engine light off. Accessing the codes will only tell you the malfunctions the vehicle's computer has recorded. Codes can be erased with a scanner, but if the problem has not been fixed, the check engine light will always come back on.
