Status Light Indicators: Notes
WARNING: This page is about a different car, the 1992 Oldsmobile Toronado. However, it is still accessible from the selected car via links, so may be relevant.
During self-diagnostics, status light display on ECCP or CRT monitor is used to indicate switchable parameter status. Each parameter status is indicated by its status light being turned on or off. Status light indicators are relative to system level being tested (BCM or ECM). See Fig 1 .
