C4 Corvette "Change Oil" Indicator Reset

The "Change Oil" indicator is reset by using a sequence of Driver Information Center (DIC) key presses as follows:

1. Turn ignition "ON", but do not start engine. (ALDL pin "G" should NOT be grounded.)

2. Press the "ENG/MET" button and release, then, within 5 seconds, press it again.

3. Within 5 seconds of Step 2, press and hold the "GAUGES" button. While the button is held, the "Change Oil" indicator will flash.

4. Continue holding the "GAUGES" button until the "Change Oil" indicator stops flashing and goes out, indicating successful completion of the reset cycle. This should take about 10 seconds.

If it does not successfully reset, turn ignition "OFF" and repeat the procedure from Step 1.
