Can someone tell me how to enter the ISC motor override E.5.3 on my '90 Deville? The tech manual states:
"With ignition ON, engine OFF, enter ISC motor override E.5.3. Press WARMER button on ECC. The fuel data centershould display E.5.3 and 99 alternately".
I can't get E.5.3 to appear. What am i doing wrong?
Thanks, all!
