Replacing instrument cluster 2009 Tahoe: what do I need to know?

[jared999]

Is this plug and play or will I have to program the cluster to my vehicle?
Will I lose the odometer data? I'm not sure where that data is stored, is it in the ECU or cluster?

Thank you

stored in cluster, the cluster normally should be programmed to your vin and proper mileage added at the same time. reason being some features in the dic may or may not function based on vin of your vehicle. so ya you could just throw one in there and it will work for the most part just won't be right.
and if you need to drive it with the cluster removed you can, just note that it may throw a ocde for unable to communicate with cluster if you do but won't hurt anything, and of course you won't know if you are low on fuel, etc, etc, just something to keep in mind.
to clarify the mileage is on the cluster, on the 2015+ it is stored in the BCM and Cluster.

Do you know if the Tech2 and only the tech2 can be used to program the cluster?

I found a thread on using the tech2 for the 03-06 model years but that doesn't apply to my model year.

Reconfiguring Instrument cluster with Tech2 and TIS

I put the stepper motor for Trans Temp in my cluster a while back (2005 Tahoe) when I replaced the whole set due to one of them acting up. Unfortunately, from what I can tell 2004-2006 have to be reprogrammed to turn on the Trans Temp gauge. Mine will zero on power up, but won't move off zero...

I found this thread but it only generally talks about a tech2 and the guy took it to a dealer to get it programmed.

There is a thread on this forum of where guys live who have a Tech-2. DIC menu options can also change when GM Accessories are programmed into the vehicle such as the Tilt and Shock Sensors or 2-Way Advanced Remote Start. I assume said options are programmed into the ECM? If so, since the ECM...

I remember that you use the Tech-2 to capture data from the old cluster to program into the new one. What I don't remember is if the ACDelco TDS system is involved or if this is all done through the scan tool.

that can only be done with a tech2 with a brand new oem cluster, will not work for a used one. pretty much anyone that sells or services speedometers can write the eprom with a tool (not the tech2)
