Displaying Trouble Codes: Notes
WARNING: This page is about a different car, the 1991 Cadillac Fleetwood and 1991 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
Following the segment check (see ENTERING SELF-DIAGNOSTICS under SELF-DIAGNOSTICS in this article), the numerals "8.8.8." appear on the FDC for one second. The display of these 3 numerals signals that the trouble code display is about to begin.
