I have a digital cluster going in place of my analog STX cluster monday. I know it works in the truck as I plugged it in and started the truck but I did not get to check all the features. I asked a tech at the dealer today about loading as built dat a to the new cluster and he eluded that it would be difficult to do this. The reason being that the as built data was for a analog cluster and you couldn't just load it on the digital cluster. Any truth to this?

He also said he was unsure but the thought it would probably throw several u codes. Anyone that has done the swap have any first hand experience with this?

Any techs or anyone know this?????? I seem to get conflicting answers.

Might be possible using as built data from the donor trucks vin#, any 1 or all modules can be independently programmed as needed. No guarantee's it will fully function.

Never tried it my self but in theory it should work.

It's got the donor trucks as built data. Hoping the features match mine and this is a non issue. Guess we will see monday

Bring all your keys and fobs along because they will likely have to be reprogrammed as well.

Truck started fine when I plugged the new key in. I didn't check the locks yet so I'll add that to the list of things to check out.

Do you have pics of old vs new?

This is the new one in the truck. The stock is the basic cluster without the LCD screen. Everything seems to work and the truck started fine. Perhaps a better question is what is store in the cluster vs what is stored in the BCM. It seems like most of the functions are in the BCM and it communicates it to the cluster. The oil pressure, coolant temp, gas gauge, and trans temp gauge, and tach all worked properly.

Found some interesting info on the IPC and BCM and how they communicate.

The Controller Area Network (CAN) uses network termination to improve communication reliability. Termination modules are located at both ends of the network. As network messages are broadcast in the form of voltage signals, the network voltage signals are stabilized by the termination resistors.

Each termination module has an internal 120 ohm resistor that bridges across the positive and negative bus connection. With two 120 ohm resistors located in a parallel circuit configuration, the total network impedance, or total resistance, is 60 ohms.

Network termination improves bus message reliability by stabilizing bus voltage and eliminating electrical interference.

The BCM is the gateway module, translating messages on the HS-CAN to the MS-CAN and vice versa, allowing a message to be distributed throughout both networks.

Vehicles equipped with the 4.2-inch screen or 8-inch touchscreen audio units use an I-CAN network for these modules. The IPC is the gateway module, translating messages on the HS-CAN to the modules on the I-CAN , and vice versa. This allows messages to be distributed throughout both networks, if required.

The BCM and IPC are the only modules on this vehicle that have this ability.
