73k on car, ck engine lt came on on hwy today. Did ECU diagnostic process (key off, test lead in block A port #6, key on, press test button for 1 second (LED lights while pressing button), release test button and NOTHING. No 1-1-1, no codes, nothing. Repeated procedure two more times but to no avail. No driveability issues, replaced ignition switch 2-3 months ago so probably unrelated.

Any help is appreciated.

95 turbo has motronic fuel system. Terminal A-6 is not used. Fuel system codes are retrieved from A-2. And don't forget the trans can set a check engine light. (A-1)

Makes sense to me. Thanks for the direction, I'll hit A1 and A2 tonight and see what she tells me. Thanks again!
