Immo Off MED17.3.3
Immobilizer systems play a crucial role in modern vehicle security, preventing unauthorized engine starts. The BOSCH MED17.3.3 ECU (Engine Control Unit) integrates an immobilizer function, ensuring that only a programmed transponder key can start the engine.
In some cases, disabling the immobilizer—often termed “immo off“—is an essential step.
Immobilizer: function and reasons for disabling
An immobilizer is an anti-theft mechanism embedded in the ECU. It requires communication between the key transponder and the ECU to allow engine ignition.
However, disabling the immobilizer may be required in specific situations:
- Lost or damaged keys: When replacement keys are unavailable.
- ECU replacement: To ensure compatibility with a used ECU.
