Where is the brain box in a 06 Saturn Ion?

In a 2006 Saturn Ion, the brain box, also known as the Engine Control Module (ECM) or Powertrain Control Module (PCM), is typically located in the engine compartment. It can be found on the driver's side, mounted near the firewall, usually close to the battery. Accessing it may require removing some covers or components for better visibility. Always consult a repair manual for specific details and procedures.
