Important Installation Notes
Please note that after installation, a relearn procedure may be required for certain features like theft system, injector setup, and crankshaft variation. This ensures security features align perfectly and your vehicle runs efficiently. Refer to your owner’s manual or consult with a professional mechanic if you’re unsure about the process.
Additionally, as the buyer, it is your responsibility to ensure proper installation and relearn procedures are followed. Failure to do so may result in damage to your vehicle or the ECM module itself.
