Automatic Display DTC Mode

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

The automatic display feature allows you to read each module DTC display function in an automatic display sequence. Each system module DTC will be displayed for 3 seconds followed by a 1 second pause before the next DTC is displayed in an automatic sequence. If no DTC information is available from the system currently displayed on the IPC, the IPC will display NO CODES for that system. If there is a communications problem between any system, the IPC will display NO COMM when the IPC is trying to communicate with that system. When all DTCs have been displayed for all systems, the IPC will display NO MORE CODES for 2 seconds before entering the manual mode. At any time during the automatic display function, the manual display feature can be activated by pressing any button on the DIC except the E/M button. The E/M button is used to completely exit the DIAGNOSTICS mode at any time.
