Immo off solution for Bosch M7.9.52: Compatible with Toyota, Peugeot and Citroën
The Bosch M7.9.52 ECU is used primarily in small 1.0L petrol engines such as the 1KR-FE, found in compact city cars from Toyota, Peugeot, and Citroën. This engine control unit features a built-in immobilizer system that prevents unauthorized starting by requiring a valid key transponder signal. While this is essential for theft prevention, it can pose a challenge when replacing the ECU or adapting a used unit, particularly in cases where keys are lost or mismatched.
An immo off procedure disables the immobilizer function within the M7.9.52 ECU, allowing the engine to start without requiring a matched key. This is particularly valuable for mechanics and tuners handling vehicles where key programming tools are unavailable or when quick ECU replacement is needed.
