Self-Diagnostic System: Notes

WARNING: This page is about a different car, the 2000 Chevrolet Corvette, 1999 Chevrolet Corvette, and 1998 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Diagnostic Trouble Code (DTC) tests are written specifically for use with GM Tech 1 or 2 scan tools. Generic scan tool can be used, but may have limited functions.

DTCs may be retrieved and cleared by using a scan tool or by using the Driver Information Center (DIC) located on Instrument Panel Cluster (IPC). When using the DIC to retrieve DTCs, if a DTC exists display will indicate whether DTC is current (with a "C") or history (with an "H"). When E/M button (switch 5) on DIC is pressed at any time, IPC will exit diagnostics mode. On-board diagnostics will also be exited automatically if no DIC buttons are pressed for longer than 60 seconds.

NOTE: For more information on Driver Information Center (DIC), see ANALOG INSTRUMENT PANELS - CORVETTE article.
