I think these are the right codes off of my truck. I just put a new check engine bulb in so I could get the codes for my overdrive and ABS not working. I have a 92' D350 and I got the following. 1-2, 2-4, & 5-5. Can someone help me out or tell me if these are not even the right numbers. I turned the key on and off 2 times then left it on the 3rd time. I then counted the flashes. and put the dash in where there was a puse. Thanks Bill

 

12= start of codes<br>55 = end of codes<br><br>so 24 is your only real code, but I don't know what it is
