The Engine Control Module (ECM) on a 2003 Chevrolet Suburban is typically located in the engine compartment, mounted on the driver's side near the firewall. It can be found behind the air intake and is secured with bolts or clips. To access it, you may need to remove some components for better visibility and reach. Always ensure the battery is disconnected before attempting to service the ECM.
