Is there a way to pull codes without a diagnostic computer? Stopped by my friends house, he couldn't find his computer (he is in the midst of moving his shop, things are scattered everywhere). He mentioned there may be a way of getting the code by turning the key on and off a few times, told him I would send a message to this board to find out. Any way to get the code by turning the key on and off? This is a 2005 5.7L.

Thanks.

 

disregard, just searched the forum and found in the body of some posts how to get the code, toggle the key 3 times and code appears where the mileage is.
