My little display that is on the ceiling of my 04 diesel excursion has stopped coming on. If i tap on it it will come back on for a bit the turn off again. Anyone had this issue, and if so how did you fix it?

 

Yes, most of us have had this issue... There's a thread on here on how to re-solder the terminals that crack off.... If you search ebay there is a company here in south Florida that will repair it for you... Either way a very very cheap repair.

 

Yep Yep, What LivingLarge said.

 

Tech sticky as the top has the link on the repair process.

 

Fowler, Fowler, is it fixed yet?

 

lol used and abused

 

NO, not fixed yet. Havent had the time to take it apart. Found a guy on ebay that i can send it off to to have it fixed.

 

Just send it off, much easier

 

Our 2002 display works, but is frozen at 10.4 mpg. Is a stuck display another symptom of the poor solder joint problem? If the readout always displays 10.4 it seems the data from the computer may not be updating.

 

Did you try resetting it R&T? Hold both buttons down at the same time and it should reset

 

Thanks, holding both buttons down reset the display to zero. We've had our 2002 2WD Limited a couple of weeks and it didn't come with an owner's manual. There are so many bells & whistles on this thing. I'm looking for a used set of manuals on ebay.

 

After a while the display will settle on an MPG and rarely move as it is the cumulative MPG since last reset. So in theory that could have been the average MPG over the trucks life since 2002 barring a reset. As more data is logged the variation will diminish and settle on a mean MPG. However, I wouldn't take the lie-o-meter too seriously.

 

Curious if there is a consensus on how far off the MPG display is. When my Excursion was closer to stock height and I was running 265s, my meter was showing about 22 mpg (+ / - ) when I reset it during some highway driving. I have yet to go far enough to hand calculate highway mileage with it, but 22 hwy. seems reasonable considering I have hand calculated with my 97 F350 4X with 4:10s / 285s @ 20.6 mpg (mostly highway but some mixed driving).


Several friends have told me their lie-o-meters in their (various brands) trucks are fairly accurate. Good friend on his second Dodge / Cummins claims the mileage displays in both his Dodges have been ridiculously accurate, and he tracks his mileage daily.

 

Mine is reset every tank and is with.3 mpg just about every tank some tanks .5mpg above what it actually is
