In a 2000 Mercedes ML320, the engine immobilizer is part of the vehicle's electronic control unit (ECU) and is integrated within the ignition system. It typically functions in conjunction with the key's transponder chip to prevent unauthorized engine start. If you're experiencing issues with the immobilizer, it may require a diagnostic tool to troubleshoot or reprogram the key. The immobilizer system is not a separate physical unit that can be easily located.
