Context
The immobilizer/anti-theft module is a critical component in the 2002 Chevrolet Corvette, ensuring the vehicle's security. Part numbers such as 12488519 and 12488520 are essential for replacement. When sourcing this part from a junkyard, look for 1997-2004 Chevrolet Corvettes or 1998-2004 Camaros as they share the same module. Key inspection points include checking for physical damage, corrosion on connectors, and ensuring the module is intact without water intrusion. Installation typically requires reprogramming to match the vehicle’s key fob, so it’s advisable to have a professional handle the installation. Common failures can include intermittent no-start conditions or failure to recognize the key fob, often due to module failure or connection issues.
