Non-Immobilizer Programming (AVALON & CAMRY)

Ensure vehicle is not equipped with engine immobilizer system. Install new ECM. Turn ignition on for more than 2 seconds. Turn ignition to ACC or LOCK. Repeat ignition on/off cycle 4 times. Ensure ignition stays on more than 2 seconds on fourth time or vehicle will not start and ECM is permanently damaged. When ignition is on for more than 2 seconds the fourth time, "without engine immobilizer" code will be registered in ECM.
