Enter diagnostics mode and when it says "PCM?" press the fan up button. Then press the fan down button until you reach "PCM CLEAR CODES?" and press the fan up button again. It should read "PCM CODES CLEAR" for a second before directing you to the next option in the submenu. You can simply turn the key off at this point to exit diagnostics mode. :)
