I followed the instructions in another post on how to fabricate a code reader for my 91 mmax. I have my code reader LED all made up, and I connected it to the 2 pins on the diagnostic plug. It just flashes off and on. Does anyone know what that means? I have the codes, and a blinking LED is not a valid code. Does that mean no codes found?

well I found my own answer -

No Codes--normal

The Lamp will illuminate for 0.5 seconds, then stay Off for 0.5 seconds, this pattern will repeat until the ignition is turned OFF.
