Guage Cluster Computer Questions

tekkitan · July 17, 2008

I am sorry if this is posted elsewhere, I wasn't sure what to search for exactly. I have an 03 Tahoe LT and I was wondering if anyone had more information on the computer in the that keeps track of the trips, MPG, etc.

The dealer I bought it from said there is usually a DVD that comes with the car explaining how to use it. I was wondering if there is some sort of way to reset all the info on it (including MPG). Reason I ask is because my AVG MPG seems to stay at 15.1mpg and hasn't changed in the month I have been driving it no matter how I drive. Also I don't know how to reset the trips or anything. I have tried resetting the computer by disconnecting the battery (for something else i was doing), but it kept everything so I assume it has a memory.

Thanks in advance.

From the owners manual....

Average Fuel Economy:

Press the fuel information button until AVG appears in the display. Average fuel economy is how many miles per gallon your vehicle is getting based on current and past driving conditions.

Press and hold the select button while AVG.ECON is displayed to reset the average fuel economy. Average fuel economy will then be calculated starting from that point. If the average fuel economy is not reset, it will be continually updated each time you drive.

To reset the personal or business trip information, do the following: press and hold select button for two seconds while in one of the personal or business trip modes. This will reset all of the information for the personal or business trip, or if your vehicle does not have the DIC steering wheel control buttons, press the reset stem on the instrument panel cluster.

You can also reset the PERSONAL: XX MI, or BUSINESS: XX MI, while they are displayed by pressing the reset stem on the cluster. If you press and hold the reset stem or select button for four seconds, the display will show the distance traveled since the last ignition cycle for the personal or business trip.
