HowToRepairGuide.com: How to reset oil change indicator on 2006 Yukon Denali?

I ALREADY CHANGED OIL,BUT ITS STILL SHOWING CHANGE OIL WARNING ON DASH.

CAN I RESET THIS ?

PLEASE HELP!!

I would assume the oil life index was not reset at last oil change. At this point you can only estimate how many miles you have driven in the month and then do another oil change at or around 3000 miles +/- When you do next oil change, be sure to reset so from there on out its accurate. In the meantime you can reset to get the light out and this will basically reset to the 3000 per say. Now.. the system does not calculate by mileage but looks at other factors to determine. Although changed a month ago, and... if in fact it was reset. Then you most likely do need oil change again, have done and do the reset. At this point no way to tell if reset last oil change or you changed yourself and did reset and yes,, you do need another oil change.

Engine Oil Life System :---

When to Change Engine Oil :---

Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oil life system to work properly, you must reset the system every time the oil is changed.

When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL message will come on. Change your oil as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the system must be reset. Your dealer has GM-trained service people who will perform this work using genuine GM parts and reset the system. It is also important to check your oil regularly and keep it at the proper level.

If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed.

How to Reset the Engine Oil Life System (This detail is From Owner's Manual)

The Engine Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE ENGINE OIL message being turned on, reset the system.

To reset the CHANGE ENGINE OIL message, see "Engine Oil Life System" under DIC Operation and Displays for vehicles that have the DIC, or do the following:

Turn the ignition key to RUN with the engine off.
Fully press and release the accelerator pedal slowly three times within five seconds.

- If the OIL LIFE RESET message flashes for 10 seconds, the system is resetting.

Turn the key to LOCK.

If the CHANGE ENGINE OIL message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure. If it still does not reset, see your dealer for service.
