Yes, that is the one I was trying to communicate with, guess that explains why I can't. Is there a way to get into and pull codes for the ASR and Electronic accelerator/ cruise cntrl/ idle speed module?

For ASR, you need to build a hand-held LED blink code reader... the scanner doesn't support communication with the ASR module. This isn't a big deal, IMO, since there are only analog codes anyway, and I'm not sure what if any live data there is.

For the EA/CC/ISC (aka E-GAS module), the scanner will communicate with that with the appropriate key (either S-20 or S-21, I forget which), and it will display digital (3-digit) codes as well as live data. If you're not seeing the option on the menu of the scanner for this, don't forget to scroll the menu to see additional options...
