Bosch ME17.9.23 Immo off in vehicles
The Bosch ME17.9.23 ECU is commonly used in small-displacement petrol engines found in Renault/Nissan vehicles, such as the Renault Kwid 0.8L 12V (2015 and newer). These vehicles use integrated immobilizer systems within the ECU to prevent unauthorized engine start. When keys are lost, the ECU is replaced, or synchronization fails, an immo off is often necessary to regain functionality without pairing complications.
