AFAIK, only Chryslers have/use the check engine light to blink the codes. Without cranking the engine, turn the ignition key to run, off, run, off, run, and almost every Chrysler product will flash trouble codes at you with the check engine or power loss/limited light on the dash.
The code scanner I am talking about does not display digital codes. It simply uses a light and a tone to flash the codes at you. You get the manual with it that is more complete than that website you listed.
