2006 escalade how do i reset my average fuel economy

[Jim1460]

My Escalade says it's getting 11.4 MPG. I'd like to reset it. Not sure how.

I think you're talking about the DIC, but I wasn't aware this was even equipped on a '06.  On the GMT-900 platform trucks, usually holding the check mark button in for a few seconds will reset whatever screen your on to zero.

 

If you're talking about a fuel composition reset (which is only on the 900 series as well as far as I know), you'll need to go into the "special functions" menu on a good scan tool to reset that. That will directly affect your mileage - not just a number in the display. The 900 series uses an algorithm (A completely crappy one at that ...) to calculate alcohol content with a flex-fuel engine. It's CONSTANTLY wrong, and needs constant resetting. The older 800 series platforms had an actual alcohol sensor, which although failure prone, was a better system than this.

In the Escalade you cannot reset it unless you pull the battery cable and even then I don't think it resets.

It is only an average of the past 100 miles. You might be able to switch to the Avg and use the stalk to reset it but still unsure.

 

@jsdirt 800s had DICs all the way back in 2000. At first it was a separate module in the center console for Denalis and Escalades and then it was put in the cluster in 2003.
