Immo off Denso 89661-02D91
The Denso 89661-02D91 ECU is equipped with an integrated immobilizer system that restricts engine start to authorized keys only. While this security measure is effective for theft prevention, it can become an obstacle in situations such as ECU replacement, loss of original keys, or communication faults within the immobilizer system.
Our immo off file service, powered by CK Decode, provides a reliable way to disable the immobilizer function in this ECU, restoring engine start capability without requiring original immobilizer components. This solution is especially valuable for workshop environments handling used or mismatched ECUs.
