This is the way you pull up any diagnostic codes that are stored in your Computer, also referred to as an Engine Control Module (ECM) or Power Control Module (PCM).

You Start with the key in the IGNITION in the OFF position. You have to turn the key to the ON position three times with the key ending in the ON position.

This is what it looks like, OFF, ON, OFF, ON, OFF, ON.

The computer should enter the diagnostic mode and will display any coded on the Odometer Display. It will have a letter and four numbers. If there are more than one codes, it will scroll through them. When it is done the word "done" should turn up on the odometer. A code might look like this; P0301

Now when you check the codes, you will see that code P0301 means that the computer detected a misfire in the number 1 cylinder.
