jesse222,

use a scantool to safely clear fault codes.

In some pre-OBD II vehicles, disconnecting the battery or pulling the PCM fuse to clear the memory and turn CHECK ENGINE light off.

But i think, your car have an OBD II. Disconnecting the battery or pulling the PCM Fuse may or may not clear the codes and will just create more problems in your car with the following examples:

1) Disconnecting battery or pulling PCM Fuse may cause loss of important information that the PCM needs to function correctly.

2) In some vehicles, loss of power to the PCM may cause it to forget transmission settings and other essential data's.

It is recommended to use scantool or scanner software to do it. Only not the dealer can do the reset, all you have to do is to buy that stuff. i like AutoTap.

thank you gonna buy the tool thanks again
