Does anyone know if the pcm's on 04's keep track of gas mileage even if you don't have the optional steering wheel controled driver info center? I'm looking at a diagnostic tool called "scangauge" that reads codes, ect., but also has the ability to read mileage figures.

 

Mine gives out a average mile per gallon which is set on 14.6 and can't seem to get any better. Other then that I am not sure what your asking.

 

Example, if you replace the PCM your milage stays the same. The cluster stores it. I have not experianced the units with no steering wheel controls.

Hey, cstchevy, incase you have not experianced this. For the avg mpg readout. It drove me crazy for a while. I drove in the city to work & back for 4 weeks and it read 14.5, then took a 250 mile trip on I-75 @ 75mph and it did not go up. It was still averaging in the 4 weeks of city mpg. Somehow I missed in the manual how to press & hold the enter button to reset it.
It's nice that we can get on the highway and get that avg alone.

 

ok, I thought i just got that but wasn't sure. I fill up about every 8-9 days and that's on 40 miles a day plus probably 75-50 miles for the weekend. So I guess it's pretty close. havne't taken a road trip yet in the truck.

 

Can anybody answer the original question? I'm curious about this myself. I don't have steering wheel control of the display but are all the same features available?
