Immo off Denso 89661-02B80
The DENSO 89661-02B80 is a factory ECU used in the Toyota Corolla models from 2002 to 2004. These ECUs include an integrated immobilizer system that requires a valid key transponder signal for the engine to start. In cases of ECU replacement or key loss, the immobilizer may prevent ignition, making an immo off solution essential.
Why perform an Immo off on Denso 89661-02B80?
Immo off is often necessary for repair professionals dealing with:
- Used ECU swaps without original keys.
- Immobilizer faults or corrupted synchronization data.
- Remote repairs where reprogramming keys is not feasible.
