14 Gauge Cluster Attempted Upgrade

JoeSCHS · July 14, 2016

I had the LT non Z71 gauges, but wanted the carbon fiber look so I purchased a Z71 cluster and got it installed. All the analog gauges work fine, but the odometer just reads dashes and the total engine hours is off significantly.

Does anyone have any experience with this or how to correct it?

Wait ... my Z71 is suppose to have carbon fibre dash. I think that might be part of the carbon package or something.

Stupid question but you are not from Canada and bought a US cluster or vice versa did you? Other than that I have no clue.

Carbon fiber is probably the wrong term, but the Z71's have some sort of pattern on the tach, speedo, etc compared to the plain black on the normal LT'S.

Nope.. I live in US, parts supposed to be from US, everything is in miles and mph.

Mine is just straight black. 2015 - HOU interior. But now you have me curious please take a pic.

Now that I think about it 99% sure this would have nothing to do with Z71 as all that adds in the mono tube shocks, under body shields and off road tuning. Should not be any interior differences ... to my knowledge.

I think it's part of the All Terrain package:

Those are the GMC's the Chevy's are slightly different.

Yes the Chevy's have a z71 symbol similar to the all-terrain (those that are z71).

Ah thank you sir. That makes more sense and might just be bias but not a big fan of that though I do like the All Terrian letters. As the guy 'who basically bought the 2015 SLE Z71+premium+loaded in the one year it was not AT pkgd' I am jelly lol

Wait so I missed out on Z71 lettering and AT lettering at the same time?

Me right now:

Did you not get your new cluster programmed? Who did the install? Most of that info is maintained within your cluster, not your truck, so the new cluster needs to be programmed with your old cluster's information.

Did not get it programmed, I thought it was plug and play. Should have known better. Where/how do I do I go about getting it programmed?

You just hosed that cluster, it has to be done before it is put into the truck.

You might message GTPrix on here, he is the only guy that can program them and does them for the dealers thru a company he partnered up with. I believe he said in another thread awhile back, if the programming is not done before the cluster is installed is bricks the cluster permanently.

Cluster has to be programmed by the dealer and odometer mileage transferred to the new cluster. Old odo mi./km. information is maintained by OnStar.

Z71 appearance items for cluster, door sills, door holds, quarter panel, grille =

If you paid somebody to do the install, I would put it back on them to correct the situation. If you just bought it from a dealer, I'd have them fix it. If you bought one off ebay or something, you might be SOL.

Not that I have experience doing so, but I do know electronics and data pretty well. I would think there was a way to 'flash' the unit if anything and then 'start over' if not I do not understand why such a thing would not be included.

Would that be a legal/regulation thing mandated that you cannot reset it because of scams or what not?
