Immo off IAW4LV.Z
The immobilizer is an anti-theft system integrated into the vehicle’s ECU, preventing engine start without the correct key signal.
While essential for security, it can cause issues when the key or transponder fails. In these cases, disabling the immobilizer—known as immo off—becomes a practical solution, especially for diagnostic or replacement purposes.
