The ECM in a 2003 Chevy Tahoe can be found in the engine compartment near the battery on the driver's side of the compartment. This is a large black plastic piece that has a bundle of wires that lead into it. If You are having problems with Your ECM then You will want to use an OBD II scan tool first to see if there are any codes that are stored in it. If there are not any codes then You will want to reset the ECM. To reset it You will need to disconnect the battery wires on it and then attach them together and allow the energy to drain from the vehicle.
