Absolutely great explenation.
The diagnostic connector I belive is under the steering wheel (it looks like it).
At different times I connected and disconnected air mas flow sensor, and other sensors, also tried to start the car with the blown fuse in the black box close to right fender and after replacing it. Tried disconnecting the battery. the rearview mirror was disconnected.
Is it possible to clear the codes on my own without the special tool or it must be connected to the special tool.?
