[QUOTE=cphilip;2048382]Got it... Power suppled correctly to the tester, then plug into the pins wanted to explore, flip switch, and count the flashes. One flash is good. More flashes means read corresponding list to determine reason.

No " flip the switch".... it is NOT a toggle sw...the switch has to be a Momentary/ Norm Open PB type switch...which is a push button switch..Normally OPEN ...you have to turn ON the key and then push the switch ON for 2-4 seconds.. that 2 sec. is the initiation sig to the module being tested ...release and then the code will flash back..write down the code and do the procedure again..they will keep flashing back in numerical sequence until the first one re-appears..you then know the module has gone thru the entire storage bank. Go to next pin w/odd color lead and do it again for that module. etc....
Ideal is a Single Flash, but I doubt you will see that .
