Resetting Change Oil Light on C4

[metalbeast]

Still riding around with your Change Oil light on in your beloved C4 because you can't figure out how to turn the darn thing off? I have had this same problem in the past. Here are the instructions for turning this nusance off.

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.

Thanks for this info. I've been dealing with the annoying question from many guest passengers, "Do you need to change your oil?" I'm a faithful oil changer and do it myself every time, even if it costs me more. Dang Econolube and/or Jiffy Lube seem to forget to put the oil cap back on after filling it. That's one mess I'm only going to clean up once.

Glad I could be of help to you on this. It took me forever to figure out how to turn that stupid light off.
