EPROM Check Without Opening Case

Every once in a while, it's useful to be able to check whether an ECU really has an EPROM or not without opening the case. The following picture shows how to check this. If you look through those holes on the bottom side of the case, you will either see bare, green PCB material (which indicates non-EPROM) or you'll see the EPROM pins. If you see the EPROM pins as illustrated, then the ECU is an EPROM model ECU and would most likely be compatible with ECMLink (assuming everything else checks out of course).
