Alright, just did the swap the other day and havent had time to really look into it, except for a little. But i have a 05 tahoe and swapped in a i believe a 04 Esky cluster. When i plugged it in, the battery light is on, and comes on right away and doesnt go out. Turn the ign to just acc and the light is on and shouldnt be, not until the next turn on the switch. Now i have found this, can anyone confirm this:
If it's an 05~06 cluster in an 03~04, the Power management SOH is missing, since you don't have that circuitry/module. That wasn't a problem prior but may be with the 06 runs now..
SOH is the "State of Health" report upon power-up. If the module doesn't respond (not there) a fault sets. In this case, no codes would set for something not in the system normally, unless the cluster itself does now.
If you have a late model cluster.. And if you have an 03~04, have the dealer reprog your cluster to the vehicle, or you'll have the 05~06 DIC. :9: It may also correct the problem.
-The 05+ has EPM, the earlier trucks don't, and their clusters fault on this in an 05+- no doubt.
03: The basic DIC
04: Add the TPM (Tire pressure Monitor)
05/06: Add the EPM system, and remove some DIC features like Instant MPG..
So is it b/c i put in a 04 into my 05 b/c i do have the instant mpg feature which according to the above, i suppose is only a 04 feature. My stock cluster did not have that option.
If it comes to reprogramming it, does anyone with a 05/06 esky cluster want to trade, or a 2500 want to trade, guage face i dont care about, changing it anyway. Or i can fix this one somehow. My mech is confused on it.
thanks for the help
