2. Step 2 Turn the ignition key to the run position. Make sure the engine is off.
   
3. Step 3 Press the button for "Read" on the code scanner. Within less than 1 minute, the scanner will display all failure codes that are stored in its memory.
   
4. Step 4 Write down the failure codes displayed by the scanner. Cross-reference the codes with the code sheet that comes with the scanner. The codes are displayed with a letter followed by a four-digit number code. Deciphering these codes by cross-referencing them with the code sheet offers an explanation of the failure.

6. Step 6 Turn the ignition key on, keeping the engine off. Press the "Erase" button on the scanner. Start the vehicle and allow it to run for 5 minutes. Watch for the check engine light to come back on. If it does, the problem has not been corrected. If it stays off, the problem has been successfully resolved.
