Location of control module power circuit on police 3.9limpala 2009

Rebalancing a tire can't possibly have anything to do with anything that could set a trouble code for vibration accelerating. The C0900 has to do with the electronic brake control module (EBCM) - and high voltage. There is testing that should be performed for this. This may or may not have to do with the concerns you are experiencing. It's too hard to say. You'll need a shop manual and wiring diagram to trace the circuit you are looking at, but diagnostic testing is really what's needed from the start.
